植物化学调查的苔，Lethocolea glossophylla，产生了五个新的异戊二烯化联苄基衍生物。它们的结构经波谱分析鉴定为2-羧基-3-甲氧基-4，6-二（3-甲基-2-丁烯基）-5，4 '-二羟基-联苄基，2，4-二-（3-甲基-2-丁烯基）-3，5，4 '-三羟基-联苄基，2，2-二甲基-5-羟基-6-（3-甲基-2-丁烯基）-7-[2-（4 ′-羟基苯基）-乙基]-色烯，2，2-二甲基-5-羟基-7-[2-（4 ′-羟基苯基）-乙基]-8-（3-甲基-2-丁烯基）-色烯和具有色烯和色满部分的双异戊二烯化的联苄（舌叶素）。从扁壳中分离并鉴定了2-（3-甲基-2-丁烯基）-3，5-二羟基联苄和2-香叶基-3，5-二羟基联苄。(C)1997年爱思唯尔科学有限公司
Phytochemical investigation of the liverwort, Lethocolea glossophylla, yielded five new prenylated bibenzyl derivatives. Their structures were elucidated by spectral analysis as 2-carboxy-3-methoxy-4,6-di-(3-methyl-2-butenyl)-5,4'-dihydroxy-bibenzyl, 2,4-di-(3-methyl-2-butenyl)-3,5,4'-trihydroxy-bibenzyl, 2,2-dimethyl-5-hydroxy-6-(3-methyl-2-butenyl)-7-[2-(4'-hydroxyphenyl)-ethyl]-chromene, 2,2-dimethyl-5-hydroxy-7-[2-(4'-hydroxyphenyl)-ethyl]-8-(3-methyl-2-butenyl)-chromene and as a bisprenylated bisbibenzyl (glossophyllin) with a chromene and a chromane moiety. From Radula voluta, the previously known bibenzyls, 2-(3-methyl-2-butenyl)-3,5-dihydroxy-bibenzyl and 2-geranyl-3,5-dihydroxy-bibenzyl, were isolated and identified. (C) 1997 Elsevier Science Ltd.
