Novel phenolics HM-1(3), HM-2(5), HM-3(6), and HM-4(7) were obtained from phytopathogenic fungus Helicobasidium mompa which causes violet root rot against mulberry and several kinds of fruit trees. Compounds 3 and 7 could be precursors of helicobasidin and deoxyhelicobasidin, which have already been isolated from the same oriqin, while 5 and 6 were unusual types of C15-compound.
新型
酚类化合物 HM-1(3)、HM-2(5)、HM-3(6)和 H
M-4(7)是从导致桑树和多种果树紫根腐病的植物病原真菌 Helicobasidium mompa 中获得的。化合物 3 和 7 可能是已从同一种口琴中分离出的 helicobasidin 和 deoxyhelicobasidin 的前体,而化合物 5 和 6 则是不常见的 C15-化合物类型。
