Piper nigrum leaves were collected from five locations from Kerala within a radius of 150 km, altitudinal variance of 1000m and annual rainfall variance of 1400mm. The extracted Piper nigrum leaf oil was profiled using a GC-MS, Beta Caryophyllene was the only constituent that was present in all the five locations, of which the highest concentration was noted in the high altitude region of Idukk...

In this study, the relationship among four species of Polygonum (including P. hyrcanicum (three samples), P. persicaria, P. avicular, and P. hydropiper) was investigated by GC profiling. Furthermore, the major compounds of the ethylic ether extract of P. hyrcanicum were identified by GC/MS as: -bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydrate (13.0%), -elemol (10.5%) and trans-longipin...

Azorean Cryptomeria japonica is widely used for local wood production, generating large amounts of aerial-part biomass residues that can be a sustainable source value-added bioproducts. This comparative study aimed (i) to determine the yield and chemical profile essential oils (EOs) extracted by hydrodistillation from C. foliage, leaves, male cones (MCs), female (FCs), (ii) investigate antimicr...

objective: this study is designed to extract and examine chemical composition, antimicrobial and antioxidant activity of the hydro-distillated essential oil of murraya koenigii leaves from the south region of tamilnadu, india. matherials and methods: gas chromatography (gc) and gas chromatography-mass spectrometry (gc-ms) analysis of the essential oil result was indicates the 33 different compo...

Furthermore, the major compounds of the ethylic ether extract of P. hyrcanicum were identified by GC/MS as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydra...

Background and Objectives: Essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. Origanum vulgare L. subsp. vulgare is one of the most distributed subspecies within the genus Origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes...
