Abstract Two new guaiane-type sesquiterpene dilactones, porelladiolide and 3α,4α-epoxyporelladiolide and a new germacranolide, 3β-hydroxycostunolide, together with the previously known germacranolides, guaianolides, pinguisane-type sesquiterpenes, and a sacculatane-type diterpene dialdehyde have been isolated from the liverwort, Porella japonica and their structures have been established by the spectral
摘要 两种新的愈创木酚型倍半萜烯双内酯、porelladiolide 和 3α,4α-epoxyporelladiolide 和一种新的germacranolide、3β-hydroxycostunolide,连同之前已知的germacranolides、guaianoides、pinguisane 型倍半萜,以及从双萜醛中分离出的sacculatene通过光谱证据和一些化学转化已经确定了地衣、Porella japonica 及其结构。Porelladiolide、3α,4α-epoxyporelladiolide和带有α-亚甲基γ-内酯基团的倍半萜对稻壳中水稻根的萌发和生长有抑制作用。
