Study on Chemical Constituents of Polygonatum odoratum
Twelve compounds were separated and purified from the ethyl acetate extracts in the alcohol solution of Polygonatum rhizome by silica gel and Sephadex LH-20 column chromatography,respectively.Their structures were identified as ningpogenin (1) ;6-O-p-hydruxybenzoylaucubin (2) ;3,3'-Bisdemethylpinoresinol (3) ;5-Hydmxymethyl-2-furancarboxaldehyde (4) ; (22E,24R)-Ergosta-7,22-dien-3β-ol (5) ; Borreriagenin (6) ; Cerevisterul (7) ; 5 α,8 α-epidiory(22 E,24R)-ergosta-6,22-dien-3β-ol (8) ;β-sitosterol (9) ; 3β,5 α,9α-trihydroxyergosta-7-22-dien-6-one (10) ; ergosta-7,22-dien-3-one (11) ;p-hydroxybenzylethanol (12).All the compounds were isolated from the plant for the first time,except the compound (9).
