| Chemical Research in Chinese Universities,2003,24(3):436-41. | | Chemical Constituents from the Roots of Biondia Hemsleyana[Reference: WebLink] | Nineteen I compounds were isolated from the,ethanol extract of the roots of Biondia hemsleyana (Warb.) Tsiang through. the repeated column chromatography on normal and reversed phase silica gel.
METHODS AND RESULTS:
By the spectroscopic and chemical evidence, their structures were elucidated as alpha-amyrin-3beta-acetate (1), Lupeol 3-hydroxyoctadecanoate (2), lupeol 3, 5-dihydroxyeicosanoate (3), cycloeucalenol (4), 4-methoxy salicylic aldehyde(5), 4-methoxy salicylic acid(6), isovanillin(7), scopoletin(8), isovanillic acid(9), cleomiscosin A (10), 2-hydroxmethyl-5-methoxylphenyl-O-beta-D-glucopyranoside (11), pregn-4-ene-3, 20-dione (12), neridienone (13), daucosterol(14), pregn-5-ene-3beta, 17alpha, 20alpha-triol-20-O-beta-D-canaropyranoside (15), periplogenin-3-O-beta-D-gluco pyranosyl-(1-->4)-beta-D-cymaropyranoside (16), pregn-5-ene-3beta, 20 (S)-diol-3-O-[2-O-acetyl-beta-D-digitalopyranosyl (1-->4)-beta-D-cymaropyranosyl]-20-O-beta-D-glucopyranosyl-(1-->6)-beta- D-glucopyranosyl-(1-->4)-beta-D-digitalo pyranoside(17), pregn-5-ene-3beta, 20(S)-diol-20-O-alpha-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside(18 , biondianoside C) and pregn-5-ene-3beta, 20(S)-diol-3-O-[beta-D-glucopyranosyl]-20-O-beta-D-glucopyranosyl-(1-->6 )-beta-D-glucopyranoside (19, biondianoside D) respectively.
CONCLUSIONS:
All compounds were isolated from this genus for the first time and 3, 11, 18 and 19 were new compounds among them. |
