[Study on Chemical Constituents of Kalimeris indica].

OBJECTIVE: To study the chemical constituents from the active fractions of Kalimeris indica. METHODS: The chemical constituents were extracted of different concentrations and isolated by silica gel, Sephadex LH-20 column and preparative HPLC. The chemical structures were further elucidated by the physicochemical characters, MS and NMR spectral data. RESULTS: Fourteen compounds were isolated and identified as α-spinasterol(1), dibutylphthalate (2), (22E,24R)-5α,8α-epidioxy-ergosta-6,22-dien-3ß-ol(3), oleanolic acid(4), coniferyl alcohol(5), umbelliferone(6), syringaresinol(7), 15-oxo-14,16H-strictic acid(8), lariciresinol(9), (Z)-3,7,11-trimethyl-1,6-dodecadien-3,10,11-triol(10), neoechinulin A(11), pinoresinol(12), 4-allyl-3,5-dimethoxyphenol(13), and 3,4,5-tri-methoxyacetophenone (14). CONCLUSION: Except compound 1, the other compounds are isolated from this genus for the first time.

[Study on triterpenoids from Wisteria sinensis].

OBJECTIVE: To study the triterpenoids constituents from Wisteria sinensis Sweet Caulis. METHODS: The compounds were beta-solated and purified with silica gel and Sephadex LH-20 column chromatography from the petroleum ether extract. Their structures were determined on the basis of physicochemical properties and spectroscopic analysis. RESULTS: They were identified as beta-sitosterol palmitate (1), alpha-spinasterol (2), (22E, 24R)-5alpha, 8alpha-epidioxy-ergosta-6, 22-dien-3beta-ol (3), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol (4), (22E, 24R) -ergosta-7, 22-dien-3beta-ol (5), 11alpha, 12alpha-oxidotaraxerol (6), lupeol (7), betulinic acid (8), 22-oxo-3beta, 24-dihydroxyolean-12-ene (9), 2alpha, 3beta, 23-trihydroxyolean-12-ene (10), soyasapogenol E (11), 3alpha, 21beta-dihydroxy-olean-12-ene (12). CONCLUSION: Compounds 1 - 12 are isolated from this plant for the first time.
