Key words:total jiegumu glycosides tablet; morroniside; TLC
Sambucus williamsii Hance(jiegumu) derived from Sambucus species of Caprifoliaceae [1].The main efficacies of jiugumu include fractures, bruises, swelling and bleeding trauma [2] Accoarding to the preliminary studies of task Force [3,4],The root of jiegumu have significantly promote fracture healing, and to clarify the material basis for total jiegumu glycosides. Task Force will total jiegumu glycosides prepared into tablets for clinical patients taking. In order to control the quality of total jiegumu glycosides tablets to ensure safe and effective of clinical use drugs,the paper established the quality standards of total jiegumu glycosides tablets.
Materials
Waters-2695 HPLC;SB-5200D ultrasonic cleaner (Experimental Instrument Factory Co., Ltd. Ningbo); electronic analytical balance (Switzerland METTLER TOLEDO company). Morroniside reference substance, (the purity of morroniside was determined to be more than 98%); total jiegumu glycosides tablets, Heilongjiang University of Chinese Medicine Department of Chemistry homemade (batch number: 20100001,20100002,20100003,0.36g/piece);methanol was of analytical grade (U.S. DIKMA company); other solvents were of analytical grade.
Methods and Results

1.1The preparation of reference substanceN the test and negative control solution.reference substance:Accurately weighed morroniside reference substance 25mg, add methanol made 5mg/ml solution. The test solution : Weigh total jiegumu glycosides tablet 0.1g, add methanol 10ml, ultrasonic treatment 30min, filtration, as the test solution. Preparation of the negative control solution : Accoarding to the prescription weigh other excipients into tablets except total jiegumu glycosides (total jiegumu glycosides 32gN lactose 288gN MCC 32gN PVPP 7gN magnesium stearate 3.5g, In accordance with the test operation is made under the negative control solution
1.2TLCIn accordance with the 2010 edition of "Chinese Pharmacopoeia" thin-layer chromatography test, draw the three solutions 5^1, Point in the same silica gel GF254 TLC plate, With chloroform - methanol (3:1) as developing solvent, Under the UV lamp view (254nm) .Test products for chromatography, chromatography with reference substance corresponding position was the same purple spots. While the negative is no reference standard chromatographic blank spots.
1.3 The content determination of morroniside.Selecting morroniside as the index components of total jiegumu glycosides tablet was measured by HPLC,and make the appropriate methodological study.Chromatographic conditions:Co1umn:Diamonsi1 C18 co1umn(250mm*4.6mm ID,5^,,Dima company),mobile phase:methanol-water(30:70v/v) detection wavelength:240nm,flow rate:1.0m1/min,co1umn emperature:room temperature,injection vo1ume:10piDetermination:the reference solution, the test solution and the negative control solution was prepared with1.1. The precise amount of the above-mentioned three kinds of solution into the liquid chromatograph, record the chromatogram peak area of morroniside.
2 The study of methodology
2.1The interference investigation of negative sample The reference solution and the negative contro1 so1ution 10pl,into the 1iquid chromatograph, the resu1ts show that negative contro1 so1ution without interference.

Ya-wen HE, Liu YANG, Hai JIANG, Qiu-hong WANG, Bing-you YANG, Hai-xue KUANG* Heilongjiang University of Chinese Medicine, Harbin, China
Abstract: Objective To reach the effect of Sambucus glycosides tablet on bone fracture healing following bone injury and its mechanism. Methods Fractures were made in the left tibiae of male New Zealand White rabbits. The fractures were made using the technique of incomplete fracture. Sambucus glycosides tablet were administered (each group at 220, 110 and 60 mg/kg doses) orally to adult Rabbits. After 12, 24, 36 days of treatment, animals were administration of marginal ear vein blood. Determination of the serum BGP, ALP, Ca2+ and P changes with determination kit. By X-ray extent of fracture healing observed in each group. After the last dose, euthanized and femur bones collected, With DEXA bone mineral density tests were performed in order to determine bone mineral density (BMD), bone mineral content (BMC) and callus area. Detect TGF-pi, BMP-2, Col- I a1 and Col-Ha1 mRNA expression in fracture healing each period using reverse transcription - polymerase chain reaction and real-time fluorescence quantitative method. Results Sambucus glycosides tablet on fracture rabbit serum ALP, serum BGP, serum P levels were significantly increased, serum Ca2+ concentration decreased; fracture zone of rabbit bone density, bone mineral content, bone callus area has significantly increased role. X-rays showed elderberry total glycosides tablet may promote healing of the fracture zone. Elderberry total glycosides tablet in fracture healing process of the BMP-2, TGF-P1 had no significant effect, can promote the expression of Col- I a1, inhibit the expression of Col-Ha1. ConclusionSambucus glycosides tablet can promote rabbit fracture late maturation and calcification of bone matrix; promote collagen synthesis and deposition of calcium salts; improve quality of callus; accelerate fracture healing.
Keywords: Sambucus glycosides tablet; fracture healing; mechanism
With bone fracture emerged as one of the most important health issues, more and more investigations are focusing on bone fracture healing. Fracture healing is a complex cascade of cellular events and the regulation of its healing remains poorly understood. Large number of clinical observations suggest that Sambucus treatment of fractures has a characteristics of short duration, rapid recovery and high efficacy.However, there are few studies on the mechanism of fracture healing.
Materials and methods
Fractures were made in the left tibiae of male New Zealand White rabbits weighing approximately 2.5 kg.The operations were performed under sterile conditions. The rabbits were anesthetized with Sodium pentobarbital. The fractures were made using the technique of Incomplete fracture.Sambucus glycosides tablet were administered (each group at 220, 110 and 60 mg/kg
