In the extremely skin irritant and caustic latex of Excoecaria agallocha the major part of the polyfunctional diterpene esters (DTE) (group I) are aliphatic polyunsaturated 9,13,14-orthoesters of the daphnane-type parent alcohol 5 beta-hydroxyresinif

From roots of Daphne papyracea Wall. two new diterpene esters, Daphne factors P 1 and P 2 , were isolated. Both are esters of the polyfunctional daphnane type: P 1 is the 9,13,14-orthobenzoate-12-(2E,4E,6E-decatrienoate) of 6α,7α-epoxy-5β,12β-dih

From a methanol extract of the roots of Wikstroemia canescens (Wall) Meisen the hitherto unknown Wikstroemia factors C 1 and C 2 were isolated by means of a Craig distribution followed by TLC. They were identified as the tigliane type phorbol-12-benz

The efficacy of varied diterpene ester type tumor promoters in suppressing the acquisition as well as the manifestation of cytolytic activity by macrophages was investigated. These mechanisms, believed to be basic to natural antitumor resistance, wer

The kinetics of the irritant response on the mouse ear [erythema measured quantitatively by the irritant dose 50 (ID50)] and its relation to the initiation-promoting activity on the back skin of NMRI mice of some polyfunctional diterpene esters were
