- 3 Downloads
Lancea tibetica is a well-known traditional Chinese herb used for the prevention and treatment of leukemia, intestinal angina, heart disease, and cough . Modern studies have demonstrated that L. tibetica possesses antithrombotic, antitumor, antioxidant, and antiviral activities [2, 3]. Our phytochemical research on L. tibetica led to the isolation and identification of 12 compounds, including nine phenylpropanoid glycosides (1–4, 8–12) and three flavonolignans (5–7). Compounds (1–9), parvifloroside A (1), acteoside (2), isoacteoside A (3), leucoseptoside A (4), sinaiticin (5), anthelminthicol A (6), hydnocarpin-D (7), styraxjaponoside C (8), and 1-O-feruloyl-β-D-glucopyranose (9), have not been recorded in Lancea genus previously. Compounds (10–12), phillyrin (10), lantibeside (11), and lantibeside B (12), have been isolated from L. tibetica previously . The structures of all isolated compounds were elucidated via comparison of their spectroscopic data (ESI-MS, 1H NMR and 13C...
