✦ Synopsis

Two novel flavonolds, llnderstln (1) and llnderatone (23, were isolated from the leaves of Lindera unbellata var. meabranacea and L. umbellata, and the structures were detemlned on the basis of chemical and spectroscopic evldencs. The deciduous small tree Lindera umbellata (Japanese name Kuromojl) is known to be rich in terpenolds and widely dlatrlbuted in Japan. This species is classified into five varieties, L. umbellata, L. umbellata var. lances, 4L. umbellata var. aembranacea, L. umbellata var. eerlcea and L. umbellata var.
