Thymus longicaulis C. Presl (Lamiaceae) is a small aromatic perennial herb and a typical representative of the Illyric-Mediterranean flora. It is a traditional remedy for cold, flu, cough, nephritis and abdominal pain

[1]. This study was aimed to evaluate phytochemical composition of the aerial parts of T. longicaulis wild-growing in Croatia. In order to find the possibility of its use in modern phytotherapy, the results were compared with those obtained for T. vulgaris, as the officially recognised medicinal plant within the genus Thymus

[2]. The presence of phenolic acids and flavonoids in the methanolic extracts and terpenes from the essential oil was detected by TLC. Chromatographic profiles were established for the studied plant extracts by LC-ESI-MS/MS and RP-HPLC-DAD analysis. All detected phenolic acids belonged to derivatives of rosmarinic acid, while all identified flavonoids were flavons. Rosmarinic acid was found to be the most abundant polyphenolic constituent (48 mg/g) while among flavonoids luteolin-7-O-glucuronide was present with

the highest concentration (14 mg/g). The extraction yield (V/m) of essential oil isolated by hydrodistillation was 1.7%. According to GC-MS analysis forty three compounds were identified, representing 99.7% of the total oil. The essential oil was characterised by a high percentage of the monoterpene fraction (95%) with a prevalence of oxygenated monoterpenes (61%). Thymol (43%), p-cymene (18%) and y-terpinene (11%) were identified as the most abundant compounds. Owing to its phytochemical composition comparable to those of T. vulgaris, this medicinal plant could be considered as a new source of the pharmacopoeial herbal drugs Thymi herba and Thymi aetheroleum.

In light of the emergence and spread of antibiotic resistance and lack of new drugs, herbal drug and antibiotic combination may represent an interesting therapy option for treat multidrug resistant bacteria. The

Tanreqing injection is Chinese herbal preparation made from Scutellariae radix (Huang Qin), Ursi fel (Xiong Dan), Naemorhedi cornu (Shan Yang Jiao), Lonicerae flos (Jin Yin Hua) and Forsythiae fructus (Lian Qiao).
