determination of volatile oil constituents in root and shoot of moringa peregrina (forssk.) fiori in saline soil
Authors
abstract
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 3 replications. the treatments were consist of control, 2, 4, 6, 8, 10, 12 and 14 ds/m. the volatile constituents were determined by gc and gc/ms. results: the results showed that the main constituent of volatile oil in control treatment was 1,2–benzendicarboxylic acid, bis (2-methyl propyl) (29.02%) which decreased with increasing salinity. in salinity treatments, the isothiocyanates compounds such as isobutylisothiocyanate and 2-isothiocyanatepropan were increased. in control level of salinity, the main compound of root volatile oil was thiocyanic acid phenylmethyl ester (29.6%) but was not found in the salinity treatment. the content of isothiocyanates in the shoot increased with increasing salinity up to 4ds/m. conclusion: the level of salinity had significant effect on volatile oil content and component of m. peregrina.

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 isothiocy...
