The volatile oils of R. canina flowers were isolated by hydrodistillation (HD) and traditional dry distillation (DD) and analyzed by HRGC-FID and GC-MS. Compared to HD, DD at 50°C leads to the isolation of high quality oil which contains the highest content of oxygenated compounds (83%). The main components are the 2-phenethyl alcohol and eugenol. The percentage of the 2-phenethyl alcohol, a highly desirable component in rose oil, was significantly higher (58.4%) in DD extract when compared to that of HD one (13.6%). As temperature increased (100°C) during DD, the oil quality decreased. The most significant changes were observed in 2-phenethyl alcohol percentage (4.5%). Moreover, an increase of alkanes/alkenes and the production of furan derivatives were observed. So, DD at moderate temperature (50°C) seemed more suitable to improve the volatile oil quality and hence, to make more value of R. canina.

This study was conducted simultaneously in different locations in Çanakkale, Balıkesir and Kütahya in order to determine the effect of location on the volatile oil components, volatile oil rate and volatile oil quality of Abyssinian sage, Musk sage and Medical sage (Salvia aethiopis L., Salvia sclarea L. and Salvia officinalis L. (hybrid)) plants from the 2015 growing season. Field experiments were carried out in 3 replicates according to the randomized block design. These plants’ volatile oils were obtained by the hydrodistillation method (GC-MS/FID) and the volatile oil rates in three different locations were measured as 0.53%, 0.21%, 0.20%, respectively. The basic components of the volatile oil were determined as follows: β-caryophyllene 36.22%, 30.46%, 35.96%, α-copaene 15.06%, 16.46%, 16.58%, germacrene-D 13.23%, 20.01%, 15.20%, β-cubebene 5.62%, 7.04%, 6.93%, α–humulene 8.68%, 7.40%, 8.54%, caryophylleneoxide 7.40%, 1.82%, 3.53%. No volatile oil was acquired from Salvia sclarea L. except for the Çanakkale location which was only 0.02% and the main components in this volatile oil were measured as germacrene-D 20.78%, and phytol 17.81%. The best volatile oil contents from Abyssinian sage and Musk sage were obtained from the Çanakkale location with 0.53% and 0.02%, respectively. The rates of volatile oils from Medical sage (Salvia officinalis L. (hybrid)) were 1.00%, 1.40% and 0.96%, respectively, in the three locations. The main components in this volatile oil were measured as α-thujone 46,00%, 44.53%, 35.78%, β-thujone 5.05%, 6.31%, 8.61%, camphor 10.73%, 19.15%, 18.68%, 1.8-cineole 8.99%, 7.23%, 5.06%, viridiflorol 1.85%, 2.28%, 4.23%. The highest volatile oil rate in Medical sage was reached at the Balıkesir location at a rate of 1.40%. As a result of this study it was found that volatile oil components are comparatively richer in terpenes and the amount of volatile oil differs according to ecological factors.

The experiment was conducted in Sabahia Horticultural Research Station, Alexandria, Egypt during the period from February 2005 until July 2007. Spear and pepper mint fields were planted late February and harvested in June 2005. The oil from the herbs was extracted by steam distillation method in a private factory in 6-October city. Then, the storage experiment was started in the middle of July 2005 and extended for two years.Dark and clear glasses, 25 ml, were filled with the oils to study the effects of the presence vs. absence of oxygen in the bottle atmosphere (half full vs. full filled bottles), dry oil vs. moisted oil (1% moisture), darkness vs. light (dark vs. clear glasses) and the effect of room temperature vs. low temperature (4oC) on the oils quality during storage. Each treatment was represented by 3 bottles, used once only in each sampling every three months for 9 times lasted for 24 months, June 2007, including the starting point samples. Storing either spear mint volatile oil or pepper mint volatile oil dry, away of air, in dark and placed in a refrigerator is recommended to keep the oils quality in good status. The active compounds will be remained in the acceptable levels and retard it far from spoilage for longer time, it might reach 24 months.

The chemical profile and allelopathic effect of the volatile organic compounds (VOCs) produced by a dominant shrub Serphidium kaschgaricum (Krasch.) Poljak. growing in northwestern China was investigated for the first time. Serphidium kaschgaricu was found to release volatile compounds into the surroundings to affect other plants’ growth, with its VOCs suppressing root elongation of Amaranthus retroflexus L. and Poa annua L. by 65.47% and 60.37% at 10 g/1.5 L treatment, respectively. Meanwhile, volatile oils produced by stems, leaves, flowers and flowering shoots exhibited phytotoxic activity against A. retroflexus and P. annua. At 0.5 mg/mL, stem, leaf and flower oils significantly reduced seedling growth of the receiver plants, and 1.5 mg/mL oils nearly completely prohibited seed germination of both species. GC/MS analysis revealed that among the total 37 identified compounds in the oils, 19 of them were common, with eucalyptol (43.00%, 36.66%, 19.52%, and 38.68% in stem, leaf, flower and flowering shoot oils, respectively) and camphor (21.55%, 24.91%, 21.64%, and 23.35%, respectively) consistently being the dominant constituents in all oils. Eucalyptol, camphor and their mixture exhibited much weaker phytotoxicity compared with the volatile oils, implying that less abundant compounds in the volatile oil might contribute significantly to the oils’ activity. Our results suggested that S. kaschgaricum was capable of synthesizing and releasing allelopathic volatile compounds into the surroundings to affect neighboring plants’ growth, which might improve its competitiveness thus facilitate the establishment of dominance.

The natural drying of Rosmarinus officinalis Linn. herbs severely affects its volatile oil quality and yields, which is reported here for the first time. The oils obtained through hydrodistillation from fresh, one, two, and three-weeks dried herbs were analyzed by gas chromatography–mass spectroscopy (GC–MS) and gas chromatography–flame ionization detector (GC-FID), and the yields were 198 ± 3.45, 168.7 ± 5.11, and 97.8 ± 1.27 mg, respectively, as compared to the internal referral standard of 327 ± 5.91 mg yield of the one-week dried herbs’ oil. Camphor, the major constituent, significantly depleted from 20.96% to 13.84%, while bornyl acetate yields increased from 1.42% to 12.46% (p values < 0.0001) in three-weeks drying, reflecting the redox processes undergoing within the oil during drying. Several constituents (25) were found in one-week dried herbs’ oil as compared to the fresh, two-, and three-weeks oils, which consisted of 23, 19, and 14 constituents, respectively, leading to the recommendation of the one-week drying of the herb for maximum oil yield. The DPPH (2, 2-diphenyl-1-picryl-hydrazyl) reactivity was highest for the two- and three-weeks dried herb-based oils, followed by the one-week dried- and fresh-herb-based oils (p < 0.0001), again indicating major chemical changes during herbs’ dryings, affecting the free-radical scavenging capacity of these batches of oils obtained after different drying times.

The aims of the research were: to know species diversity of fern (Pteridophyte) from Pangajaran, Wonosalam, Jombang, to know fern species containing volatile oil, to know concentration and percentage similarity of substances and characteristics of the substances containing in the oil, and to know the structure of cell producing volatile oil in trees and leaf of the fern. Fern diversity was studied by field survey, volatile oil concentration measured by hydro-distillation followed with gas chromatography to further know the components in the oil, while structure of the cell producing volatile oil was detected cross section of the trees and leaf for microscopic analysis. Based on the data and analysis result can be concluded that there were 13 fern species in Pangajaran. Two of the 13 species were confirmed as producing volatile oil, Pteris beaurita Linn. and Cyathea contaminans, that were produced volatile on their leaf only. Concentration of volatile oil of leaf P. beaurita was 0,005%, while in C. contaminans 0,01%. Percentage similarity of the volatile oil between two species based on its Retention Time (RT) was 2,5%, at the RT point of 21.247 in P. beaurita and at RT point of 21.294 in C. contaminans. Percentage similarity of both species based on morphological characters was 36.36%. Location of volatile oil producing cells in both species of fern was spreadly dispersed in schlerenchyma tissue and in mesophyll tissue of the leaf.

Volatile oils were obtained by hydrodistillation from Gliomastix murorum and Pichia guilliermondii, two endophytic fungi isolated from the traditional Chinese medicinal herb Paris polyphylla var. yunnanensis. The oils were analyzed for their chemical composition by gas chromatography-mass spectrometry (GC-MS). Palmitic acid (15.5%), (E)-9-octadecenoic acid (11.6%), 6-pentyl-5,6-dihydropyran-2-one (9.7%), and (7Z,10Z)-7,10- hexadecadienoic acid (8.3%) were the major compounds of the 40 identified components in G. murorum volatile oil. 1,1,3a,7-Tetramethyl-1a,2,3,3a,4,5,6,7b-octahydro-1H-cyclopropa[a]- naphthalene (25.9%), palmitic acid (15.5%), 1-methyl-2,4-di- (prop-1-en-2-yl)-1- vinylcyclohexane (7.9%), (E)-9-octadecenoic acid (7.3%), and (9E,12E)-ethyl-9,12-octadecadienoate (5.2%) were the major compounds of the 27 identified components in P. guilliermondii volatile oil. The in vitro antimicrobial activity of the volatile oils was also investigated to evaluate their efficacy against six bacteria and one phytopathogenic fungus. The minimum inhibitory concentration (MIC) values of the volatile oils against the test bacteria ranged from 0.20 mg/mL to 1.50 mg/mL. One of the most sensitive bacteria was Xanthomonas vesicatoria with an MIC of 0.20 mg/mL and 0.40 mg/mL for G. murorum and P. guilliermondii, respectively. The mean inhibitory concentration (IC50) of the volatile oils against spore germination of Magnaporthe oryzae was 0.84 mg/mL for G. murorum and 1.56 mg/mL for P. guilliermondii. These results indicated that the volatile oils from the endophytic fungi have strong antimicrobial activity and could be a potential source of antimicrobial ingredients.
