Neolignans and Caffeoyl Derivatives from Selaginella moellendorffii

Ten new phenolic compounds including the six neolignans 1-3 and 6-8 and four caffeoyl derivatives, i.e., myo-inositol 1-caffeate (9), myo-inositol 6-caffeate (10), myo-inositol 5-caffeate (11), and paucine 3'-beta-D-glucopyranoside (12) were isolated from the whole plants of Selaginella moellendorffii (caffeic acid = 3-(3,4-dihydroxyphenyl)prop-2-enoic acid). Their structures were established by spectroscopic and chemical methods.
