A bioassay-guided fractionation and chemical examination of antihyperglycemic root extract of Derris indica resulted in isolation and characterization of two new furanoflavanoids (1, 2) along with thirteen known compounds (3-15). Their structures were determined on the basis of extensive spectroscopic

Propenylbenzenes are often used as starting materials in the chemical synthesis of aroma compounds and fine chemicals. In the present study, we demonstrate the ability of an Arthrobacter sp. to transform various structures of propenylbenzenes derived from essential oils to

The allelopathic effect of caffeic acid was tested on root growth, phenylalanine ammonia-lyase (PAL) and peroxidase (POD) activities, hydrogen peroxide (H(2)O(2)) accumulation, lignin content and monomeric composition of soybean (Glycine max) roots. We found that exogenously applied caffeic acid inhibited

Biosynthesis of hydroxybenzoates even at enzymatic level is poorly understood. In this report, effect of feeding of putative biosynthetic precursors and pathway-specific enzyme inhibitors of early phenylpropanoid pathway on p-hydroxybenzoic acid accumulation in chitosan-elicited hairy roots of Daucus carota was
Salicylic acid (SA) is a key endogenous component of local and systemic disease resistance in plants. In this study, we investigated the role of benzoic acid (BA) as precursor of SA biosynthesis in tobacco (Nicotiana tabacum cv Samsun NN) plants
