Studies On Chemical Constituents And Quality Appraisement Of Cultivated Cistanche Salsa

Herba Cistanches, the dried fleshy stems of Cistanche genus plant (Family Orobanchaceae), is one of the well-known traditional Chinese medicine herb as a tonic. It has the functions of strengthening the Kidney, moisturizing dryness by nourishing blood and moistening the intestines and laxation. Due to the overdose exploitation, its natural resources are facing with exhaustion. Though two species of Cistanche genus plant are documented as the sources of Cistanche in China Pharmacopeia (2005 edition), i.e. C. deserticola, C. tubulosa, the results have shown that Herb Cistanches is the dried fleshy stem of C. deserticola and C. salsa in the investigation of th original plants recorded in the herbalogical works of the past dynasties. C. salsa is a perennial and parasitic herb distributing in the northwest of China. Up till now. the chemical investigations of C. salsa is very few, and artificial cultivated C. salsa have not been undertaken. In order to effective utilize and further expoilation, systematic study was conducted on the dried fleshy stem of artificial cultivated C. salsa in this dissertation. The results as followed:Twenty-three compounds were isolated from the 70% ethanol extracts by various chromatographic techniques and twenty compounds were identified on the base of spectroscopic methods. These compounds included: seven phenylethanoid glycosides, three terpenoids, three alkaloids, three sterols, and four others. Among them, one was the new compound, five compounds were reported in Cistanche genus plant for the...
