裸花紫珠叶的化学成分

Chemical constituents from the leaves of Callicarpa nudiflora

摘要

摘要: 采用硅胶、Sephadex LH-20、C₁₈等柱色谱方法对裸花紫珠Callicarpa nudiflora Hook.ex Arn.叶的正丁醇萃取部位进行分离纯化，分离得到13个化合物。通过¹H NMR,¹³C NMR等波谱技术和化学反应鉴定化合物的结构。13个化合物分别为木犀草素( 1 )，木犀草苷( 2 )，芹菜素( 3 )，5，7，4′-三羟基-3′-甲氧基黄酮( 4 )，木犀草素-3′-O-β-D-葡萄糖苷( 5 )，芹菜素-7-O-β-D-葡萄糖苷( 6 )，Luteol-in-7-O-(6″-trans-caffeoyl)-β-D-glucopyranoside( 7 )，Luteolin-7-O-(6″-trans-cinnamo-yl)-β-D-glucopyranoside( 8 )，arjunglucosideⅠ( 9 )，Luteolin-7-O-(6″-p-coumaryl)-β-D-glucopyranoside ( 10 )，forsythoside B ( 11 )，isomartynoside ( 12 )，deacylisomartynoside ( 13 )。其中，化合物 11 为首次从该植物中分离得到，化合物 4，7~ 10，12~ 13 为首次从该植物属中分离得到。

Abstract: From the n-butanol extract of the leaves of Callicarpa nudiflora， thirteen compounds were isolated by repeated column chromatography with silica gel，C₁₈and Sephadex LH-20.Their structures were identified by spectroscopic (¹H，¹³C NMR and so on) and chemical methods as luteolin ( 1 )，luteolin-7-O-β-D-glucopyran-coside ( 2 )，apigenin ( 3 )，5，7，4′-trihydroxy-3′-methoxyflavone ( 4 )，luteolin-3′-O-β-D-glucopyranoside ( 5 )，apigenin-7-O-β-D-glucopyranoside ( 6 )，luteolin-7-O-(6″-trans-caffeoyl)-β-D-glucopyranoside ( 7 )，luteolin-7-O-(6″-trans-feruloyl)-β-D-glucopyranoside ( 8 )，arjunglucoside I( 9 )，luteolin-7-O-(6″-p-coumaryl)-β-D-glucopyranoside ( 10 )，forsythoside B ( 11 )，isomartynoside ( 12 )，deacylisomartynoside B ( 13 ).Among them，compound 11 was isolated from this plant for the first time and compounds 4，7-10，12-13 were isolated from this genus for the first time.
