Naturforsch. 40c, 321 — 324 (1985); received November 26, 1984/February 13, 1985 Pluchea odorata, Asteraceae, Leaf Resin, Flavonoid Aglycones, Terpenoids The chemical composition of the leaf resin of Pluchea odorata has been studied from material collected in Tamaulipas, Mexico. It mostly consists of triterpenes and phytosterols and an eudesmane type sesquiterpene. Very small amounts of ten different flavonol aglycones occur, dissolved in this resin; most of them are 6-methoxy compounds. A comparison with previous results on material from El Salvador shows that the latter contains a lesser number of triterpenes and especially of flavonoids, but more sesquiterpenes, while the n-alkane composition varies only quantitatively between both populations.

Many traditional healing plants successfully passed several hundred years of empirical testing against specific diseases and thereby demonstrating that they are well tolerated in humans. Although quite a few ethno-pharmacological plants are applied against a variety of conditions there are still numerous plants that have not been cross-tested in diseases apart from the traditional applications....
متن کاملNew Phenolics from Baccharis Leaf Exudate
A previous study on the leaf resin composition of some Baccharis species revealed that the resinous material consists mostly of terpenoids, in which more or less lipophilic flavonoid aglycones are dissolved [1]. In B. salicifolia, a major terpenoid was found to be the rare triterpene maniladiol [2]. The major flavonoids were penduletin (6 -hydroxykaempferol3,6 ,7-trimethyl ether) and pinocembri...
