Acknowledging the importance of medicinal compounds, flavonoids, and phenolic acids in plants and human health; understanding the best time to harvest plants to get the most potentially therapeutic biological activity; and predicting and controlling the quality of medicinal plants are very useful. The rich chemical composition of medicinal lavender, as well as its antioxidant activity, has led to its wide application in the pharmaceutical, cosmetic, and food industries. In the current research, seasonal differences in phenolic content; the main constituents of essential oil, essential oil yield, and antioxidant activity; and flavonoid content were evaluated. In this investigation, for all the investigated factors, three replications were considered as completely randomized designs. The predominant natural components were α-pinene, camphene, 1,8-cineole, limonene, camphor, borneol, cryptone, isobornyl formate, cumin aldehyde, carvone, caryophyllene oxide, and epi-α-cadinol. The highest rate of 1,8-cineole was seen in summer, while camphor and borneol showed their highest percentages in the cold season. Some of the compounds such as caryophyllene oxide, isobornyl formate, and cumin aldehyde showed their highest amounts in the spring with the activation of some important plant enzymes such as peroxidase. The total content of flavonoids and some phenolic compounds (coumarin and p-coumaric acid) increased when plants received sunlight for a longer time than in the colder to warmer seasons. On the other hand, increases in chlorogenic acid and vanillin were observed in spring. Also, the highest antioxidant activity was observed in lavender, which was accompanied by an increase in the important phenolic composition of rosmarinic acid in the cold season. Generally, this investigation provides beneficial evidence about the most appropriate harvest time for lavender to produce the most favorable constituents for optimization in food, pharmaceutical, and herbal products.

“…The HS-GC-MS technique was efficient in detecting main hydrocarbons when evaluating volatile compounds in red algae (ALENCAR et al, 2017). In a study with Trigonella elliptica, the static headspace technique efficiently detected volatile compounds that were also detected by GC-MS and GC-FID analysis of essential oils (BAHMANZADEGAN et al, 2017).…”

Varronia curassavica is a medicinal species native to Brazil; its anti-inflammatory properties are attributed to α-humulene and β-caryophyllene. This study to investigated the population variability of V. curassavica. Leaves were collected from 40 individuals of a natural population and transferred to glass flasks (2 mL). The volatiles were extracted and analyzed using static headspace gas chromatography coupled with mass spectrometry (HS-GC-MS). A total of 17 compounds were detected: monoterpenes (1.6% - 68%) and sesquiterpenes (25.7% - 79.0%), including α-humulene and β-caryophyllene. Multivariate analysis was performed to estimate the dissimilarity of individuals separated the compounds into four groups. Group I was characterized by the content of α-pinene, groups II and IV by β-caryophyllene, and group III by β-pinene. The abundance of α-humulene showed small variations; while β-caryophyllene showed larger variations that contributed to the population variability. This is the first report on the chemical composition analysis of volatile compounds in V. curassavica using the HS-GC-MS technique.

The massive pomaces of Punica granatum L. exhibit a challenging losses exposure difficulty for the processing industries. The resent study was aimed to investigate the bioactive compounds of pomace extracts to introduce it to different industries such as pharmaceutical, food, medicinal, agricultural etcetera for optimum use. Four different extracts were prepared and the phenolic compounds were quantified using HPLC-DAD. Different amounts of phenolic compounds were detected in the samples including gallic acid, catechin, ellagic acid, rosmarinic acid, hesperidin, p-coumaric acid and chlorogenic acid. Gallic acid was major compound in all studied extracts of pomaces, with the maximum amount belonging to water extract (at 60°C). The average amount of gallic acid detected in water extract (at 60°C) of Punica granatum L. was 11.25 mg g -1 dry weight, while it was 3.24 3.02 and 1.09 mg g -1 dry weight for the extracts obtained by distilled water, methanol and methanol 80%, respectively.
