| Summary: | 碩士 === 南台科技大學 === 生物科技系 === 101 === Fifty-eight compounds were isolated from the fresh whole plants of Adenostemma lavenia (L.) O.Kuntze. Among these isolates, forty-one compounds were characterized by comprensive analyses of their 1D and 2D NMR and mass spectral data. They are α-cadinol, ent-11α,15α-dihydroxykaur-16-en-19-oic acid, ent-11α-hydroxy-15α-acetoxykaur-16-en-19-oic acid, ent-11α-hydroxy-15-oxo-
kaur-16-en-19-oic acid, adenostemmoic acid B, adenostemmoic acid C, adenostemmoic acid G, phytene-1,2-diol, 3,7,11,15-tetramethylhexadecane-1,2-diol, phytol, phytal, 3-methylidene-2-oxo-7,11,15-trimethylhexadecanol,
ent-9-hydroxy-15-oxo-kaur-16-en-19-oic acid, ent-11α,16α-epoxy-15α-hydroxy-16S-
kauran-19-oic acid, adenostemmolide A, hyalic acid, adenostemmolide B, adenostem
molide C, adenostemmolide D, adenostemmolide E, adenostemmolide F, p-hydroxy
benzaldehyde, p-hydroxybenzoic acid, 4-(4-hydroxyphenoxy)benzaldehyde, vanillic acid, stigmasteryl-3-O-β-D-glucopyranoside, squalene, aristophyll-C, phellophyll-a, α-tocopherol, 1, 2-bis-(5-γ-tocopheryl)-ethane, α-tocopherylchinon, 2,2,4-trimethyl-
1,3-pentanediol diisobutyrate, ethylenic triacylglycerol, triacylglycerol, 3-nonenoic acid, mixture of β-sitosterol and stigmasterol, mixture of β-sitosterol and stigmast-7-en-ol and mixture of cis ferulic acid and trans ferulic acid,. Among them, adenostemmolide A, adenostemmolide B, 4-(4-hydroxyphenoxy) benzaldehyde, adenostemmolide C, adenostemmolide D, adenostemmolide E, adenostemmolide F was reported for the first time from natural sources as new compounds.
