Abstract 4β-Hydroxygermacra-1(10),5-diene, thujopsan-2α,-ol and hedycaryol were found in the leaf oil of Cryptomeria japonica obtained by hexane extraction. Both the first and last were present in all races of C. japonica native in Kyushu main island, but thujopsan-2α-ol was found in about one-third and not found in C. fortunei so far examined. Moreover, some C. fortunei lacked 4β-hydroxygermacra-1(10)
摘要 4β-Hydroxygermacra-1(10),5-diene, thujopsan-2α,-ol 和hedycaryol 在正己烷提取的银杏叶油中发现。第一个和最后一个都存在于九州本岛原产的 C. japonica 的所有种族中,但 thujopsan-2α-ol 在大约三分之一中被发现,而目前在 C. Fortunei 中没有发现。此外,一些 C. Fortunei 缺乏 4β-hydroxygermacra-1(10),5-diene。另一方面,一些仅包含这种作为倍半萜醇。当叶子被蒸汽蒸馏时,4β-羟基germacra-1(10),5-二烯异构化为α-cadinol,hedycaryol异构化为elemol和eudesmols。Thujopsan-2α-ol 由 Mayurone 合成。
