Introduction
For centuries, trade caravans on a long and dangerous journey from China to the west were scrutinized very carefully. Traders are fined for violating the law, and sometimes
all goods are confiscated. Immediately, however, the death penalty awaited everyone trying to carry at least a few yellows, tiny grains, transparent silk wound particles - silkworms like testicles.
Silk served as money in China, producing paper from silk, and writing books before the invention of silk. For 100 years, for example, it was written in the silk classic of the Chinese historian Sima Qian, which consists of 130 chapters (Yurovskaya, M.A., Kurkin, A.V., Lukashev, N.V., 2007; Uwaydah, J. M., Aslam, M., Brown, C.H., Fitzhenry, S. R., Me-donough, J. A., 1997; Shakhidoyatov, H. M., 1988; The search for pathogenic pesticides in a number of 2-thioxoquinazolinov-4, 1982; Kalinin, F. L., Merezhinsky, Yu. G., 1965; Sapaev, B. et al., 2021; Saitkulov, F. E. et al., 2014; Sapaev, B. et al., 2022; Saitkulov, F. et al., 2023; Saitkulov, F. et al., 2022).
With long and great profits, China was sold to the West with the oldest most expensive and luxurious fabrics-silk. They were regularly shipped in large quantities to the Mediterranean coast, and yet production remained a mystery to the Europeans for a long time. According to the ancient Chinese philosopher Confucius, the Chinese were well versed in silkworm breeding 3,000 years ago. China's neighbors, and even loved ones like Korea and Japan, have only known the secrets of this product for centuries. For centuries, China has kept the secret of silk production, which has led fans astray. In Greece and Rome, for example, silk was believed to have been made from the lower part of birds living in high mountain trees that were almost inaccessible.
Despite the fact that the Mulberry treeng Root is very well developed, this plant is a very demanding plant for nutrients, temperature, moisture, soil composition.
So, despite the fact that the root system of the mulberry tree is developed, the more abundant and qualitative leaf mass, and in order to increase the amount of Hydrocarbons contained in the fruit, the incense must be formed on fertile, soft-grained land (Saitku-lov, F. et al., 2022; Saitkulov, F. et al., 2022; Saitkulov, F. et al., 2022; Saitkulov, F. et al., 2022; Alafeefy, A. M. 2011; Navneet Singh., Agarwal, R. C., Singh, C. P., 2013; Khodjani-yazov, Kh. U., Mamadrahimov, A. A., 2017; Byr'ko, V. M., 1984; Blokh, G. A., 1972; Koval', I. V., Usp. Khim., 1996; Brauer, G., Ed. 1963).
Most of the lands of Central Asia consist of Sandy and Sandy (Karakum, Kyzyl-Kum, Karshi steppes) soils, which well conduct wa-
ter, heat and air from themselves, but can't retain moisture and nutrients in themselves. The main reason for this can be observed that the amount of humus in the soil is very small, that is, around 0,2-0,5%, the thickness of the humus layer does not exceed several centimeters. Therefore, in such soils, the mulberry tree grows very poorly (Smith, G. E. P., Alliger, G., Carr, E. L., and Young, K. C., J. Org. Chem., 1949; Schwarzenbach, G. and Flashka, H., 1970; Klimova, V. A., 1975; Ka-linnikov, V. T. and Rakitin, Yu. V., 1980; Rao, C. N. R. and Venkataraghavan, R., 1962; Jensen, K. A. and Nielssen, P. H., 1966; Daes-cu, C., Bacaloglu, R., and Ostrogovich, G., 1973; Nakamoto, K., 1991).
It should also be noted that the application of such measures as timely processing of the tree row-to-row in mulberry and the correct path of watering is of great importance in increasing the fertility of the soil, so it is necessary to ensure that between the row-to-row of mulberries and sowing, as well as planting lands are plowed in autumn, in order for this to not happen, the incense should be watered by grinding the owners.
If we compare the reproduction of shrubs with seeds and vegetative ways in order to increase the yield of Mulberry, then in the first years of use, it is possible to make sure that in the first case, the increase in productivity is different in different environments. While it is possible to observe that the Leaf yield growth in the Bush mulberry, which is grown from Sprouts, is very sluggish, while in the Bush mulberry, which has its own roots, it was observed that the use of the Leaf sharply increases the yield in the second year, in other words, the yield of the second year leaf from the In the Bush mulberries with an acre root, the range of plants in the range of 3 meters in a row was 0,5 meters, while the number of Bush mulberries in each hectare was 3700 units, in the second year after planting from cuttings in the first year of using mulberry leaves, the yield of leaves per hectare was 2,8-3,0 tons, It can be seen that in the third year of use of mulberries, the Leaf yield obtained from Mulberry was observed in the fourth year in a permanent place in the seed - recovered mulberries, the mass of the Leaf was 2-3 tons more than in the first year, which indicates that the yield was 2,0-2,5 times higher than the (Geary' W. J.
1971; Grand' A. F. and Tamres', M. 1969; Lever, A. B. P. 1987).
The data on the development of the root system, photosynthesis in the leaves, methods of increasing the hydrocarbons content in the fruit, with the participation of various concentrated solutions of biochemical action processes of the coordination compound synthesized in the "morus alba" variety of the Moraceae plant of Mulberry, continue their scientific work in this area.
Experimental part Synthesis of quinazolin-4-one.
Method A. From the literature there are many works on the synthesis of quinazolines and its derivatives (Weisberger, A., Proskau-er, E., Riddik, J., and Tups, E. (1985; Smith, G. E .P., Alliger, G., Carr, E. L., and Young, K. C., J. Org. Chem. 1949).
We also carried out the synthesis of quinazolin-4-one in two different ways.
Method: A. Experiments were carried out in a reaction chamber flask with a volume of 100 ml equipped with reflux refrigerator. To obtain the substance quinazolin-4-one, add 13.7 g (0.1 mol) anthranilic acid
16 ml of formamide was added (p = 1.42 g/ cm3). The reaction mixture was heated to the levels indicated in Table 2 temperatures and kept for a specified time. Then the reaction mixture poured into a glass containing crushed ice and left for 6-8 hours at room temperature. Dropped Crystals filtered and dried. The output was 13.8 g quinazolin-4-one. Product further purified by recrystal-lization in water in the presence of activated carbon. Exit the purified substance was 12.87 g (88.17%). T. = 217-218 °C. (Sait-kulov, F. et al., 2022; Alafeefy, A. M., 2011; Navneet Singh, Agarwal, R. C., Singh, C. P., 2013; Khodjaniyazov, Kh. U., Mamadrahi-mov, A. A., 2017; Byr'ko, V. M., 1984; Blokh, G. A., 1972; Koval', I. V., Usp. Khim., 1996).
Method: B. Boil a solution of 4 ml (0.1 mol) formic acid and 5 ml (0.1 mol) ammonia (25%) in a water bath for 1 hour. Then 13.7 g (0.1 mol) was added to the reaction mixture anthranilic acid was continued to boil in for 5 hours. The gray sediment was washed acetone and dried. Recrystallized from water with activated carbon. Got white the color precipitate was dried. Yield: 7.8 g (53%), m.p. = 216-218 °C.

By reacting solutions of ligands with the corresponding metal nitrates in the molar ratio M: L 1:2, 1:1:1, complexes with a common value for all synthesized ones were obtained. Compounds of the formula ML2X2, where: M - Co; L-quinazolin-4-one, 6-ben-zylaminopurine; X-NO3-.
Analysis of the IR spectrum of the complex showed that quinazolin-4-one, 6-ben-zylaminopurine is coordinated. This conclusion was made based on the finding in the IR spectrum of the complex of new absorption bands at 1386 cm-1, absent in the spectrum of the free ligand.
In addition, a new band at 827 cm-1 that appeared in the IR spectrum of the complex is attributed to out-of-plane bending vibrations of the coordinated nitrate group. As mentioned above, according to coordination, the stretching vibrations of this group should split into two bands. The bands at 1473 and 1278 cm-1 found in the IR spectrum of the complex also indicate that the nitrate ligand is outer spheral.
To complement the results obtained by IR spectroscopy, an NMR spectroscopic study of the structure of the synthesized diamagnetic cobalt complexes was carried out. PMR spectra of nitrate complexes are slightly different from the PMR spectrum free ligand. In the NMR spectrum of the complexes, all signals of hydrogen-containing functional groups are slightly shifted to the weak field region compared to their location in the NMR spec-
trum of the ligand, which indicates an ongoing reaction complexation. In the NMR spectrum of the Co(N03)2L2-H20 complex, the doublet-doublet signals of the protons of the benzene ring are shifted to the weak field region and have centers at 5 7.32 and 7.84 ppm. In the 1H NMR spectrum of the Co(NO3)2 complex in the high field region at 5 1.90-1.94 ppm. a singlet signal is observed. Shift of all signals responsible for hydrogen-containing functional groups in the ligand molecule to the weak region fields, as well as the appearance of a new signal from protons quinazolin-4-one, 6-benzylamino-purine indicates coordination to the com-plexing ion. Results of PMR spectroscopic study the structures of the synthesized complexes confirmed the previously obtained conclusions using IR spectroscopy about the location of acid ligands in the internal sphere of the complex соединения.
Results analysis
Kobalt (Il)-nitrate and quinazolin-4-on, 6-benziaminopurin in the study of biochemical action processes on the "Morus alba" varieties of the Moraceae plant of the coordination compound formed by fatty acid, the following processes were carried out. In previous scientific works, one-year herbs, "Kahraba" variety of Phaseolus aureus plant belonging to the family of legumes, as well as the processes affecting the root-throwing system of the goose "Bukhara-102", "Naman-
gan-77", "Sultan", "Onkurgan-1", "C-6524" varieties are also studied.
In order to carry out the processes of biochemical action on the "Morus alba" varieties of the Moraceae plant, cobalt (II)-nitrate and quinazolin-4-on 6-benziaminopurin a coordination compound formed by fatty acid dissolved in the Absolut ethyl alcohol so that it does not decompose into ions, we prepared the necessary solution, then 200 milliliters 5% and 200 milliliters 10% increments were prepared.
The results obtained from the conducted experiments are as follows.
1. As a result of the experiment, 5% and 10% solutions of the II product were prepared in distilled water.
2. The root of the one-year plant variety "Morus alba" of 4 Moraceae plants was dipped in a 5% solution for 5 hours.
3. The root of the one-year plant variety "Morus alba" of 4 Moraceae plants was
dipped in 10% li solution for 5 hours, and the root of the one-year plant variety "Morus alba" of another Moraceae plant was dipped in ordinary water for 5 hours.
The effect of cobalt (Il)-nitrate and quinazolin-4-on, 6-benziaminopurin coordination compound formed by fatty acid on root growth was studied.
One-year plant varieties of the Morus alba plant of the Moraceae plant were transferred to the canvases (total 9 pots), watered every morning at 8-00 hours.
Moraceae plant "Morus alba", immersed in the root in a solution of 5% for 10 hours, is faster to form a leaf than the annual plant variety 5 hours, and the length of the rod in the plants was carried out in the same sequence.
It can be concluded that if the roots are dipped for 5 hours in a 10% solution compared to a 5% solution with an increase in the rate of growth of the root, it is desirable to count.

Conclusion
So this complex organic compound plays an important role in the processes of hemo-poiesis. Cobalt in plants is a microelement
necessary for the assimilation of molecular nitrogen, promotes the formation of nodular bacteria in the root system of leguminous crops.
Cobalamin, also known as vitamin B12, is well soluble in water, vitamin-related metabolism is of great importance in biochemical processes in every cell of the body of man, animal, ossicles.
Vitamins of the Group "B" are the largest and most complex vitamins in terms of composition. Cyanocobalamin and Hydroxoco-balamin are used to prevent or treat vitamin deficiency. After assimilation into the body,
they are converted into adenosylcobalamin and methylcobalamin, these compounds are important metabolites processes. All forms of vitamins of the Group " B " are a complex macrocyclic compound, biochemically occupying microelements in its composition, among these vitamins is the central atomic cobalt (II)-valence cation in the composition of vitamin B12, as well as regulating metabolic processes.
