“…These values are similar to extraction yield obtained for a nonirradiated sample (yield = 0.313%). The profile of volatile components did not change significantly with radiation [3]. The total content of hydrocarbons and monoterpenes in an irradiated sample (average values considering all irradiated materials = 57.2 and 41.8%, respectively) decreased in relation to a nonirradiated sample (60.00 and 44.14%, respectively).…”

“…The content of oxygenated monoterpenes verbenol, verbenone, α-eudesmol, β-eudesmol, (E)-p-2-menthen-1-ol, and pinocarveol in irradiated samples (average values considering all irradiated materials = 2.8, 1.8, 2.5, 7.6, 1.5, and 1.4%, respectively) are higher in relation to corresponding nonirradiated samples (2.15, 1.44, 1.90, 5.01, 1.17, and 1.22%, respectively). Irradiated samples showed higher content of the sesquiterpene α-muurolene (average values considering all irradiated materials = 1.9%) than the corresponding nonirradiated samples (1.52%) [3].…”

“…Moreover, the content of α-pinene significantly decreased in the EO from A. gigas Nakai [3]. However, the content of this volatile compound increased after exposition to γ-radiation in the aerial part EO from Z. multiflora [16].…”

“…Chromatographic analyses of EOs isolated from plant indicated that γ-radiation changes their extraction total yields and chemical compositions. Both the parameters (that is, yields and chemical composition) are mainly influenced by vegetal species, radiation dose, and chemical constituents of the plant material [3]. The present review describes the effects of γ-radiation on the chemical composition of EOs isolated from different plant parts: roots, rhizome and cortex, leaves, fruits, seeds, flowers, and whole plant.…”

Abstractγ-Radiation provides an effective alternative method to reduce or eliminate microbial contamination of medicinal herbs and other plant materials. However, a search in the literature is important to describe the effects of γ-radiation on the content and integrity of secondary metabolites from plants. The present work provides a review of the effects of γ-radiation on extraction yields and chemical composition of essential oils isolated from roots, rhizome and cortex, leaves, fruits, seeds, flowers, and whole plant. In addition, this review describes the effects of γ-radiation on terpenes. The informations in the present work may assist in research about essential oils and dose of γ-radiation that is able to biologically decontaminate without causing chemical changes in secondary metabolites. These reports in the literature can describe the behavior of many of these metabolites when subjected to various doses of radiation.

“…For plant volatiles, some studies have reported increase activity due to the action of radiation; others note that there was no systematic change in volatile profile when plants were irradiated by different doses of gamma radiation, although some investigators report a negative effect of radiation on plant volatiles (Piggott and Othman 1993;Alcarde et al 2004;Seo et al 2007). …”

Biological control of sapstain fungi in Egyptian wood stores and infected trees

Using microorganisms or their secondary products, especially volatile organic compounds (VOCs), to control wood infection by fungi has been exploited in recent years. A total of 17 local microbial isolates were screened for growth inhibition of wood-pathogenic fungi on solid artificial medium. Lactobacillus plantarum was selected as the most active VOC producer since it reduced the growth of sapstain fungi by 60-90% and that of wooddegrading fungi by 20-60%. During the interaction between the majority of the tested wood-pathogenic fungi and VOCs emitted by L. plantarum on wood blocks, both hyphal growth and conidial formation were inhibited. It was also observed that loss of wood dry weight and wood strength due to the action of pathogenic fungi was decreased to negligible values by exposing wood blocks to VOCs emitted by L. plantarum. The VOCs produced were trapped using a simple method and quantified by GC/ MS. The main constituents of the VOC profile were 1,2-benzenedicarboxylic acid, dibutyl ester, isopropyl myristate, n-nonadecane, octadecane and n-eicosane. This study also evaluated using gamma radiation to enhance microbial production of VOCs.

The effects of high dose γ-irradiation on six herbal medicines were investigated using gas chromatography-mass spectrometry (GC/MS) and high-performance liquid chromatography (HPLC). Herbal medicines were irradiated at 0-50 kGy with (60)Co irradiator. HPLC was used to quantify changes of major components including glycyrrhizin, cinnamic acid, poncirin, hesperidin, berberine, and amygdalin in licorice, cinnamon bark, poncirin immature fruit, citrus unshiu peel, coptis rhizome, and apricot kernel. No significant differences were found between gamma-irradiated and non-irradiated samples with regard to the amounts of glycyrrhizin, berberine, and amygdalin. However, the contents of cinnamic acid, poncirin, and hesperidin were increased after irradiation. Volatile compounds were analyzed by GC/MS. The relative proportion of ketone in licorice was diminished after irradiation. The relative amount of hydrocarbons in irradiated cinnamon bark and apricot kernel was higher than that in non-irradiated samples. Therefore, ketone in licorice and hydrocarbons in cinnamon bark and apricot kernel can be considered radiolytic markers. Three unsaturated hydrocarbons, i.e., 1,7,10-hexadecatriene, 6,9-heptadecadiene, and 8-heptadecene, were detected only in apricot kernels irradiated at 25 and 50 kGy. These three hydrocarbons could be used as radiolytic markers to distinguish between irradiated (>25 kGy) and non-irradiated apricot kernels.
