the volatile constituents of the aerial parts of varthemia. persica dc. var. persica, growing wild in iran, were investigated by gc-ms. sixty seven constituents were identified. ?-cadinene (9.7%), selin-11-en-4-?-ol (5.30%), germacrene d (4.9%), bicyclogermacrene (4.7%), ??muurolene (4.7%), ?-eudesmol (4.52%), ?-himachalen oxide (3.6%), ?-eudesmol (3.54%), ?-bourbonene (3.21%) were found to be ...

peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. the aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in mentha x piperita , using semiquantitative rt-pcr analysis and evaluating menthol producti...

Menthofuran rich eight half-sib seed progeny of Mentha piperita (MPS-36) were studied for various genetic parameters, namely, coefficient of variation, heritability, genetic advance, correlation, and path of various plant and oil attributes, namely, plant height, L:S ratio, herb yield, β -myrcene, limonene, 1,8-cineole, menthone, menthofuran, neomenthone, pulegone, and menthol. Maximum genotypi...

The objective of the study is to observe the anti-motion sickness effect of volatile oil extract of Pinelia ternata in rats, compare the strength of anti-motion sickness action between the Pinelia ternata volatile oil extract and the dimenhydrinate, and analyze the constituents in volatile oil of Pinelia ternata. Rats with frequency is 0.05Hz, the peak speed of 240°/s rotated to stimulate, evok...

The pulp of pitanga (Eugenia uniflora L.) is used to prepare pitanga juice. However, there are no reports on the identification and quantification of the main constituents in pitanga pulp. The aim of this study was to identify and quantify the major volatile and non-volatile low-molecular-weight constituents of the pulp. Isolation of volatile compounds was performed by solvent-assisted flavor e...

volatile constituents of the seed kernel and leaf of cultivated moringa peregrina (forssk.) fiori, agricolt collected after hydrolysis were analyzed by gc and gc/ms. five glucosinolate degradation products which constituted almost the whole isolated oil of the seed kernel were identified to be: isobutyl isothiocyanate (94.0%), isopropyl isothiocyanate (4.9%), sec-butyl isothiocyanate (0.5%), n-...

The antifungal properties of some commercial plant waters obtained as side products in producing distilled oils were investigated. Paper disc samples were impregnated with various plant waters and exposed to wood decay fungi for 3 months in Petri dishes. Ten types of plant water (Laurus nobilis, Calluna vulgaris, Lavandula stoechas, Thymus vulgaris, Myrtus communis, Eucalyptus globulus, Mentha ...

background: moringa peregrina (forssk.) fiori. is a small tree, which grows in south east of iran. the shoot and root of m. peregrina contain volatile oil which has several isothiocyanates. objective: to study the effect of salinity on volatile constituents of root and shoot of m. peregrina. methods: the experiment was conducted on randomized complete blocks design (rcbd) with 8 treatments and ...
