“…Various types of terpenes are involved in protection against photooxidative stress, attraction of pollinators, moderating thermotolerance, and direct protection against insects and microbes. Moreover, terpene metabolites are vital for plant growth and development and also interacting between plants and their environments (23)(24)(25). Therefore, the high amount of oxygenated monoterpenes in summer oil might have been due to these reasons.…”

Background: In general, seasonal growing of plants influences chemical composition and biological activities of essential oils. Objectives: Therefore, the aerial parts of Scrophularia frigida (S. frigida) were used in the current study to find seasonal variations in the content and composition of essential oil. Materials and Methods:The oil was extracted by hydro-distillation from two samples collected in different seasons, and analyzed by GC-FID and GC-MS. Results: In total, 18 and 20 components were identified and quantified in the oil of summer and autumn samples representing 97.42% and 94.77% of the oil components, respectively. The essential oil of autumn sample was mainly composed of fatty acid derivatives (42.69%). The major components of the autumn oil were palmitic acid (30.49%), phytol (12.99%), L-linalool (11.41%), and hexahydrofarnesyl acetone (6.65%). The essential oil of summer sample was dominated by oxygenated monoterpenes (68.91%), L-linalool (38.69%), geraniol (11.20%), α-terpineol (9.99%), and palmitic acid (7.32%). Conclusions: Based on these observations, wide variation is detected in the chemical composition of the oil obtained from the same plant in different seasons.

Background:The growth in the production of biodiesel, which is principally fatty acid methyl esters (FAME), has been phenomenal in the last ten years because of the general desire to cut down on the release of greenhouse gases into the atmosphere, and also as a result of the increasing cost of fossil fuels.Objective:Establish whether there is any relationship between two different species (watermelon and muskmelon) within the same family (Cucurbitaceae) on fatty acid compositions and enumerate the different fatty acids in the two species.Materials and Methods:Extraction of fatty acids from the two species and preparation the extract to gas chromatography/mass spectroscopy analysis to determine the fatty acids compositions qualitatively and quantitatively.Results:The analyzed plants (watermelon and muskmelon) contain five saturated fatty acids; tetrdecanoic acid, pentadecanoic acid, hexadecanoic acid, heptadecanoic acid and octadecanoic acid with different concentrations, while muskmelon contains an extra saturated fatty acid named eicosanoic acid. The watermelon plant contains five unsaturated fatty acids while muskmelon contains three only, the two plants share in two unsaturated fatty acids named 9-hexadecenoic acid and 9-octadecenoic acid, the muskmelon plant contains higher amounts of these two acids (2.04% and 10.12%, respectively) over watermelon plant (0.88% and 0.25%, respectively).Conclusion:The chemical analysis of watermelon and muskmelon revealed that they are similar in saturated fatty acids but differ in unsaturated fatty acids which may be a criterion of differentiation between the two plants.

“…Other substances identified in C. officinalis extracts are proteins and amino acids [16], saturated hydrocarbons [17], vitamin C [18] and mineral substances [19]. Given their strong aromas [20], etheric oils could attract insects, thereby promoting pollination indirectly [21-23]. …”

BackgroundThis study aimed to quantify the active biological compounds in C. officinalis flowers. Based on the active principles and biological properties of marigolds flowers reported in the literature, we sought to obtain and characterize the molecular composition of extracts prepared using different solvents. The antioxidant capacities of extracts were assessed by using spectrophotometry to measure both absorbance of the colorimetric free radical scavenger 2,2-diphenyl-1-picrylhydrazyl (DPPH) as well as the total antioxidant potential, using the ferric reducing power (FRAP) assay.ResultsSpectrophotometric assays in the ultraviolet-visible (UV-VIS) region enabled identification and characterization of the full range of phenolic and flavonoids acids, and high-performance liquid chromatography (HPLC) was used to identify and quantify phenolic compounds (depending on the method of extraction). Methanol ensured more efficient extraction of flavonoids than the other solvents tested.Antioxidant activity in methanolic extracts was correlated with the polyphenol content.ConclusionsThe UV-VIS spectra of assimilator pigments (e.g. chlorophylls), polyphenols and flavonoids extracted from the C. officinalis flowers consisted in quantitative evaluation of compounds which absorb to wavelengths broader than 360 nm.
