Chemical investigation of the twigs (separated from the needles) of the Himalayan yew, Taxus baccata, has culminated in the isolation of a new lignan, 4'-O-demethylsuchilactone, along with eight phenolic compounds, (-)-rhododendrol, (-)-rhododendrin, sciadopytisin, ginkgetin, kayaflavone, (-)-secoisolariciresinol, suchilactone and a lignan diol, not previously encountered in nature.Three taxoids, brevifoliol, 13-decinnamoyltaxchinin B and 10-deacetylbaccatin III were also isolated.This is the first report on the phytoconstituents isolated only fom the twigs of the Himalayan yew. - Key words: Taxus baccata; Taxaceae; twigs; phenolics; biflavones; lignans; taxoids; 4'-O-demethylsuchilactone.
Studies on the constituents of Jatropha gossypifolia Linn: Synthesis of prasanthaline, a new lignan, and isolation of dihydroprasanthaline

Prasanthaline (1), a new lignan isolated by Chatterjee et al. , has been synthesised by two routes.In the first appraoch naturally occurring suchilactone (2) on LAH reduction followed by acetylation affords 1, identical wit
GADAIN, A LIGNAN FROM JATROPHA GOSSYPIFOLIA
Banerji, J.,Das, B.,Chatterjee, A.,Shoolery, J. N.
, p. 2323 - 2328 (2007/10/02)
The isolation of a new lignan, gadain, from Jatropha gossypifolia is reported.The structure and stereochemistry of this compound have been determined from spectral analysis, partial synthesis from jatrophan (a lignan of known absolute configuration) and from its transformation reactions. - Key Word Index: Jatropha gossypifolia; Euphorbiaceae; lignan; gadain.
