Rauvolfia tetraphylla Linn. (syn. R. canescens L., family: Apocynaceae) holds an important position in the Indian traditional system of medicine, and has other immense applications. This particular plant is regarded as a rich source of a wide variety of important alkaloid constituents such as reserpine, reserpiline, raujemidine, isoreserpiline, deserpidine, aricine, ajmaline, ajmalicine, yohimbines, serpentine, sarpagine, vellosimine and tetrphylline. However, there is no report on the terpenoid constituent from this plant, and we report the isolation from the air-dried stems and branches of R. tetraphylla and structural elucidation of a new labdane diterpene, 3-hydroxy-labda-8(17),13(14)-dien-12(15)-olide (1; Fig. 1) bearing  an unusual -lactone moiety.

Effluents from electroplating industries contain large amounts of heavy metals. These must be treated before discharge into aquatic systems to prevent serious environmental damage. The yeast Saccharomyces cerevisiae, a byproduct of fermentation industries, combines high metal accumulation with low costs. However, an article in issue 4 of Chemical Speciation and Bioavailability explains how the fluoride anions present in the effluent may preclude bioremediation of chromium(III) by yeast cells.
