Studies On Chemical Constituents From Przewalskia Tangutica Maxim

Przewalskia tangutica Maxim is a plant of the genus Przewalskia tangutica of the Solanaceae family and it's Tibetan name is TangChongGaBao. Przewalskia tangutica Maxim is Rare and endangered species endemic to China. It's produced in Tibet Sichuan and qinghai province.g It is borned in the mountains above sea level 3200-5000 meters of gravel land and arid steppe as well as distributing in the area of Tibet Sichuan and qinghai province. TangChongGaBao which is widely used for anti-inflammatory analgesic,governance boils, tonsillitis cancer tumors, diphtheria.bellyache and so on.The systematicexamination of Przewalskia tangutica Maxim's Chemical constituents is the first time.Fifteen compounds have been isolated from the whole plant of Przewalskia tangutica Maxim. Fourteen of them were identified as (RS)-Hyoscyamine (1),Anisodine(2), scopolamine(3), Anisodamine(4), scopoletin(5), tetracosylferulate(6),protocatechuic acid(7).scopolin(8), fabiatrin(9), caffeic acid(10), acetamide(11), margaric acid(12), nonacosane(13), Glycerol trioleate(14). their structures were elucidated on the basis of spectral data. Compounds 5-14 were isolated from Przewalskia tangutica Maxim plant for the first time. The structure types were involving with alkaloids, coumarins, amides, phenols. The examined samples will be provided for further pharmacological screening. The study of Przewalskia tangutica Maxim's constituents in order to further understand the Przewalskia tangutica Maxim chemical composition and Belladonna alkaloids resources provide the basis for further development.
