sapogenins and lyoniside

To study the chemical constituents of leaves of Paulownia fortunei (Seem.) Hemsl.. The constituents were isolated by column chromatography and their structures were elucidated through spectroscopic analysis.. The compounds were identified as mimulone (I), apigenin (II), luteolin (III), 2alpha, 3beta, 19beta-trihydroxyurs-28-O-beta-D-galactonopyranos ylester (anserinoside, IV), 3alpha-hydroxyl-ursolicacid (V), ursolicacid (VI), daucosterol (VII), beta-sitosterol (VIII).. The compounds I - V are obtained from leaves of Paulownia fortunei (Seem.) Hemsl for the first time.

To study the chemical constituents of Oxytropis chiliophylla.. The air-dried whole plants of O. chiliophylla were extracted with EtOH (90%) three times at room temperature. The compounds were isolated by silica-gel, polyamide, C-18 and Sphadex LH -20 columns. The structures were identified based on spectral analysis.. 8 compounds were isolated from O. chiliophylla and identified as azukisapogenol (1), (22E, 24R) -24-methyl-5alpha-cholesta-7, 22-diene-3beta, 5alpha, 6beta-triol (2), apigein (3), 3', 4'-dimethoxy-quercetin-3-O-beta-D-galactopyranoside (4), 7, 3', 4'-trimethoxy-quercetin-3-O-alpha-L-rhamopyranosyl-(1-->2)-beta-D-glucopyranoside (5), (2S, 3S, 4R)-N-[(R)-2'-hydroxytetracosanoyl]-1, 3, 4-trihydroxy-2-amino-octadeca-6-ene (6), beta-sitosterol (7), daucosterol (8).. All the compounds were isolated from O. chiliophylla for the first time.
