Chemical constituents of Aganosma marginata[Reference: WebLink]

To investigate the chemical constituents from Aganosma marginata and to provide the material basis for the quality control.
METHODS AND RESULTS:
The chemical constituents were separated and purified by silica gel Sephadex LH-20,MCI.Their structures were determined by physicochemical properties and spectral data analyses. Twenty three compounds were isolated from A.marginata and identified as:periseoside C(1),3-O-β-D-glucopyranosyl-3β,15α-dihydroxypregn-5-en-20-one(2),3β,20α-dihydroxy-5-en-pregane(3),28-methylstigmast-5-en-3-ol(4),29-Norcycloart-23-ene-3,25-diol(5),29-norcycloartan-3-ol(6),geniposidic acid(7),syringaresinol(8),syringaresinol-4,4'-O-bis-β-D-glucopyranoside(9),syringic acid 4-O-β-D-glucopyranoside(10),salicylic acid(11),scopoletin(12),azelaic acid(13),3-O-[β-D-xylopyranosyl]-(l→4)-β-D-allopyranoside-14-hydroxycard-20(22)-enolide(14),bis(2-ethylhexyl) phthalate(15),kaempferol-3-O-α-L-rharnnopyranosyl-(1→4)-α-L-glucopyranoside(16),kaempferol-3-O-α-Lglucopyranoside-(1→2)-β-D-glucopyranoside(17),kaempferol-3-O-α-L-rhamnopyranosyl-(1→4)-[α-L-rhamnopyranosyl(1→4)]-β-D-glucopyranoside(18),kaempferol-3-O-α-L-rhamnopyranosyl-(1→4)-[β-D-glucopyranosyl-(1→4)]-β-D-glucopyranoside(19),hexacosanoicacid 1-carbonate(20),5,8,12-trihydroxy-9-octadecenoic acid(21),(2S,3S,4R)-phytosphingosine(22),and nebularine(23).
CONCLUSIONS:
All the compounds are obtained from plants of Aganosma G.Don for the first time.
