Chemical constituents of the roots of wild Stemona sessilifolia.[Reference: WebLink]
To study the chemical constituents of the roots of wild Stemona sessilifolia (Miq.) Miq. collected in Baohua Mountain, Jurong City, Jiangsu Province.
METHODS AND RESULTS:
The roots of wild S. sessilifolia were extracted with 75 % EtOH and partitioned by CHCl3 and n-BuOH. The compounds were separated and purified by column chromatography with silica gel and macroporous resin, and their structures were identified by spectroscopic analyses. Ten compounds were isolated from the root of S. sessilifolia in this study, i. e., one new dihydrophenanthrene named 7-methoxy-3-methyl-2,5-dihydroxy- 9, 10-dihydrophenanthrene (1), and 9 of known compounds: stilbostemin D (2), protostemonine (3), Protostemotinine (4), stemospironine (5), (-)-syringaresinol-4-O-β-D-glucopyranoside (6), benzoic acid (7), vanillic acid (8), daucosterol (9), and stigmasterol (10).
CONCLUSIONS:
Compound 1 is a new compound, compound 6 is isolated from the genus for the first time, and compounds 7 - 10 are isolated from the species for the first time.
