A New Guaiane-type Sesquiterpene with 15 Known Compounds from Wikstroemia scytophylla Diels

A new guaiane‐type sesquiterpene, wiksphyllamin A (1) with C‐10 and C‐11 connected, along with fifteen known compounds were isolated from the stems of Wikstroemia scytophylla Diels. All these compounds were isolated for the first time from Wikstroemia scytophylla. The structures of 1–16 were identified using spectroscopic methods.
