guaiene/adenocarcinoma

Two new guaiane-type sesquiterpenoids, named 4α,5α-epoxy-8β-hydroxy-1α-hydro-α-guaiene (1) and 4α,5α-epoxy-1-hydroxy-α-guaiene (2), were isolated from the whole plants of Valeriana hardwickii. Their structures were elucidated on the basis of spectroscopic analysis. Compounds 1 and 2 showed weak

Premna microphylla Turczaninow, an erect shrub, was widely used in Chinese traditional medicine to treat dysentery, appendicitis, and infections. In this study, the essential oil from P. microphylla Turcz. was obtained by hydrodistillation and analyzed by GC (Gas Chromatography) and GC-MS (Gas

This study was undertaken to assess the antioxidant and antiproliferative potential of the essential oil of Hypericum hircinum L. subsp. majus (Aiton) N. Robson. Analysis of the oil composition revealed that sesquiterpene hydrocarbons (69.3%) dominate, cis-β-guaiene, δ-selinene and (E)-caryophyllene
