摘要


中文摘要 樟科土楠(Cryptocarya concinna Hance syn.: Cryptocarya konishii Hayata ex Kawakami)為分布於華南和台灣的中型常綠喬木。在對台灣產植物進行一系列細胞毒篩選實驗中,其中土楠根部顯示具有細胞毒活性。因此,進行細胞毒活性成分研究,以生物活性為導向,從根部氯仿可溶部分離出十七個化合物:cryptocaryone (1)、infectocaryone (2)、infectocaric acid (135)、2’,4’-dihydroxy-6’-methoxychalcone (143)、kurzichalcolactone (18)、混合物cryptocaryanone A (3)及cryptocaryanone B (4)、7,8-dihydro-7-hydroxycryptocaryanone (136)、7,8-dihydro-7-methoxycryptocaryanone (137)、cryptoconcinic acid (138)、pinocembrin (133)、chalcocaryanone C (11)、kurziflavolactone A (14)、cinnamic acid (139)、pinosylvin (140)、lauric acid (141)及??-sitosterol (142),這些化合物係根據各種光譜資料證明,確定其結構。 在分離到的化合物中,infectocaric acid (135)、7,8-dihydro-7- hydroxycryptocaryanone (136)、7,8-dihydro-7-methoxycryptocaryanone (137) 與cryptoconcinic acid (138)為新的化合物。cryptocaryone (1)、混合物cryptocaryanone A (3)與cryptocaryanone B (4)對MCF-7、NCI-H460及SF-268三個癌細胞株顯示具有良好的毒殺效果。

Abstract Cryptocarya concinna Hance (syn.: Cryptocarya konishii Hayata ex Kawakami; Lauraceae) are medium-sized evergreen trees, which distributed in South China and Taiwan. In a series of cytotoxic screening-program study on Formosan plants, C. concinna was one of the active species. The bioassay-directed fractionation of the active chloroform-soluble part from its roots led to the isolation of seventeen compounds, including five chalcones: cryptocaryone (1), infectocaryone (2), infectocaric acid (135), 2`,4`-dihydroxy-6`-methoxychalcone (143), kuzichalcolactone (18), eight flavanones: the mixture of cryptocaryanone A (3) and cryptocaryanone B (4), 7,8-dihydro-7-hydroxycryptocaryanone (136), 7,8-dihydro-7-methoxycryptocaryanone (137), cryptoconcinic acid (138), kurzichalcolactone A (14), chalcocaryanone C (11), pinocembrin (133); one phenylpropanoid: cinnamic acid (139), one trans-stilbene: pinosylvin (140), one aliphatic acid: lauric acid (141); one steroid: ??-sitosterol (142), respectively. The structures of these compounds were elucidated by spectroscopic interpretations. Among these isolates, infectocaric acid (135), 7,8-dihydro-7- hydroxycryptocaryanone (136), 7,8-dihydro-7-methoxycryptocaryanone (137) and cryptoconcinic acid (138) are new compounds. Furthermore, cryptocaryone (1), the mixture of cryptocaryanone A (3) and cryptocaryanone B (4) showed significant cytotoxicity against MCF-7, NCI-H460 and SF-268 cancer cell lines, respectively.
