β¦ Synopsis
We had previously reported' the isolation of a new sesquiterpene lactone, plenolin, from Raileya pleniradiata Harv. and Gray in 0.0003% yield. Too little plenolin was obtained to permit detailed chemical investigation although the structure I was tentatively assigned on

The antitumor sesquiterpene lactones microhelenins-A, B, and C, microlenin acetate, and plenolin were isolated from Helenium microcephalum. The structures and stereochemistry of these lactones were determined by physical methods as well as by chemical transformations and correlations. Microlenin ace
Three new protoilludane sesquiterpenes, plorantinone A, B and C (1, 2a and 3), were isolated from injured fruit bodies of the Basidiomycete Russula delica, presumably formed from stearoylplorantinone B (2b) which was isolated from intact fruit bodies. The isolation and structure elucidation includin
