ABSTRACT
To study the non-flavonoids chemical constituents in water extract of Spatholobi Caulis. Some purification and analysis techniques like silica gel, D101-macroporous adsorptive resins, and Sephadex LH-20 column chromatographies as well as reversed phase high-performance liquid chromatography were used to isolate and analyze the phenolic acid esters and other type compounds from Spatholobi Caulis integrally. The structures of these compounds were identified by spectroscopic techniques such as nuclear magnetic resonance and high resolution mass spectrometries. Twenty-seven compounds, including phenolic acid, coumarin, lignan, terpene, alkaloid, and steroid compounds, were isolated from ethyl acetate and n-butanol fractions in water extract of Spatholobi Caulis, and they were identified as β-sitosterol(1), feruli acid methyl ester(2), syringaresinol(3),(+)-medioresinol(4),(+)-epipinoresinol(5), p-acetylphenol(6), bolusanthin Ⅳ(7), evofolin B(8), salicylic acid(9), trans-p-hydroxy-cinnamic acid(10), abscisic acid(11), m-hydroxyphenol(12), C-veratroylglycol(13), p-hydroquinone(14), 8,9-dihydroxymegastigma-4,6-dien-3-one(15), p-hydroxybenzoic acid(16), 6,9-dihydroxymegastigma-4,7-dien-3-one(17), protocatechuic acid(18), protocatechuic acid methyl ester(19), 5,7-dihydroxycoumarin(20), isolariciresinol(21), nicotinic acid(22), daucosterol(23),(+)-pinoresinol(24), stigmasterol(25), allantoin(26) and koaburaside(27), respectively. Furthermore, compounds 2-15, 19-22, 24 and 26 were isolated from genus Spatholobus for the first time.
