background & aim:oxidative stresses caused by free radicals are known to promote many diseases such as inflammation and cancer; therefore, any plant product that can inhibit free radical production can play an important role in preventing diseases. we aimed to compare the fracture rate and the scavenging activity of free radicals, and the antioxidant composition of rolb-transformed hairy root o...

Catharanthus roseus cell suspension cultures were employed for the biotransformation of (–)-caryophyllene oxide (1), and four metabolites, 15-hydroxycaryophyllene oxide (2), 4β ,5αdihydroxycaryophyll-8(13)-ene (3), 2β -hydroxycaryophyllene oxide (4), and 2-hydroxy-4,5epoxycaryophyllan-13-ol (5) were obtained. Metabolites 4 and 5 were found to be new compounds, and their structures were deduced ...

Background & Aim: Investigation of suspension cell culture and callus production in Catharanthus roseus. Catharanthus roseus is an herbaceous perennial plant belongs to the family Apocynaceae. C. roseus is important as commercial medicinal plant because of its alkaloidal content. Whole plant contains about 130 alkaloids those are classified as vinca alkaloids...

Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...

abstract in this study, interaction between amf (g. mosseae and glomus spp., respectively indigenous and non-indigenous of hm-contaminated areas) with cd-resistant pgprs (bacillus mycoides and micrococcus roseus, indigenous of contaminated areas) on the growth, cd and nutrient uptake of maize plant (zea mays l.) in cd polluted soil were investigated. with increasing levels of cd, shoot and root...

in the present study, plumbago zeylanica linn. (plumbaginaceae) , one of the folk medicinal plants commonly used as antifertility agent was evaluated for its antifertility effect. five successive solvent extracts, petroleum ether, chloroform, acetone, ethanol and water extracts, of the stems of p. zeylanica were studied on estrous cycle at two dose levels, 200 and 400 mg/kg respectively.   of t...

The natural occurrence of 22-hydroxylated steroids in cultured Catharanthus roseus cells and in Arabidopsis seedlings was investigated. Using full-scan gas chromatography-mass spectrometry analysis, (22S)-22-hydroxycampesterol (22-OHCR), (22S,24R)-22-hydroxyergost-4-en-3-one (22-OH-4-en-3-one), (22S,24R)-22-hydroxy-5alpha-ergostan-3-one (22-OH-3-one), 6-deoxocathasterone (6-deoxoCT), 3-epi-6-de...

BACKGROUND Salicylic acid (SA) acts as a potential non-enzymatic antioxidant and a plant growth regulator, which plays a major role in regulating various plant physiological mechanisms. The effects of salicylic acid (SA; 0.05 mM) on physiological parameters, antioxidative capacity and phenolic metabolism, lignin, alkaloid accumulation in salt stressed Catharanthus roseus were investigated. MA...
