“…[18,[22][23][24]. In addition, previous studies have reported that the essential oil composition of various medicinal and aromatic plants, when collected at different times varied significantly and the changes were mainly quantitative rather than qualitative [17,18,25]. The results revealed that the changes of essential oil content and composition of A. koreana twigs are possibly correlated with the various environmental factors commencing from different seasons.…”

“…In general, the yield and chemical composition of the essential oil producing plants have been greatly associated with the environmental parameters such as temperature, relative humidity, sunlight, harvesting season and soil properties as well as the maturity of the plant and its physiological and biosynthetic pathway [12][13][14][15][16]. Among them, the season and duration of sunlight may influence the chemistry of the plant, since many components may be stored at a specific period to respond to environmental changes [17]. In addition, the biological activity of the essential oil is mainly correlated with its chemical composition.…”

“…In addition, the biological activity of the essential oil is mainly correlated with its chemical composition. A number of studies have been reported previously in relation to seasonal influences in the yield and chemical composition of essential oils from various plant species and showed great variations in the concentration of essential oil components [12,[17][18][19] The study of the influence of seasonal variation on the essential oil composition of A. koreana twigs is required to increase the quality and quantity of essential oil production. Further, there have been no reports on seasonal variation in the essential oil composition of A. koreana twigs.…”

Objective: In the present study, the influence of harvesting time (April, June, August and October 2015) on the essential oil composition of Abies koreana twigs from Korea was investigated. Methods:The essential oil from the twigs of A. koreana was isolated by steam distillation and its chemical composition was determined by gas chromatography-mass spectrometry (GC-MS). Results:The essential oil yield was found to vary from 0.76 to 1.20% depending on the month of harvesting. The GC-MS analysis revealed the identification of 26 different essential oil components from the twigs harvested in the months of April, June, August and October, which were mostly monoterpene hydrocarbons (57.63-72.38%) followed by oxygenated monoterpenes (18.82-25.96%). Harvesting time mainly influenced on the concentration of the major components of the essential oil from the twigs of A. koreana. Limonene (17.38-31.13%), bornyl acetate (13.22-21.17%), camphene (12.56-13.26%), α-pinene (11.05-13.02%), β-pinene (4.55-5.70%), 3-carene (5.21-6.43%) and β-eudesmol (1.49-8.24%) were detected as the major components in the essential oil. Conclusion:The main differences between the essential oil compositions of four different months can be referred to limonene and bornyl acetate. The results showed considerable variations in the composition of essential oil, particularly quantitative variation during different harvesting months.

“…However, the data demonstrated that major compounds of black pepper essential oil were highly varied quantitatively than qualitatively . In particular, the variations in the chemical composition of essential oil and its contents are influenced by numerous factors, including the geographical region of the plant, maturity of the plant material, plant age, collection time, and weather parameters …”

The present study was carried out to investigate the effect of exposure of Cambodian black pepper essential oil on the human electroencephalographic (EEG) activity. In the EEG study, 20 men and 20 women healthy volunteers participated. The EEG readings were recorded from 32 electrodes placed on the scalp according to the International 10‐20 system and 25 EEG indices were analyzed. The essential oil of black pepper mainly contains β‐caryophyllene (30.53%), 3‐carene (19.85%), limonene (14.26%), β‐pinene (9.45%), and α‐pinene (5.25%). The EEG data showed that the exposure of black pepper essential oil exhibited different brain wave activity according to the gender. In women, a significant increase of spectral edge frequency 50% of alpha at C4 region was observed due to the exposure of black pepper essential oil. In the case of men, relative gamma, the ratio of sensorimotor rhythm to theta, spectral edge frequency 50%, spectral edge frequency 90%, and spectral edge frequency 50% of alpha significantly increased during the exposure of black pepper essential oil. The result revealed that the gender variation plays a major role in the EEG activity of black pepper essential oil and the exposure of black pepper essential oil may improve the cognitive functions.

“…In general, the extracts and fractions showed MIC values between 39.06-5000 µg/mL for the susceptible bacteria and fungi. It was reported that MIC values below 100 µg/mL indicate good activity; whereas values from 100 to 500 µg/mL are considered moderate; while those from 500 to 1000 µg/mL are weak; and over 1000 µg/mL are inactive [29].…”

Brachychiton rupestris and Brachychiton luridum are deciduous trees belonging to family Malvaceae. Several members of the genus Brachychiton and its related genus, Sterculia, are used in folk medicine for the treatment of infections. Herein, we investigated the antimicrobial activity of the total extracts, n-hexane, dichloromethane as well as the ethyl acetate fractions of the leaves of both species using agar well diffusion method in an effort to better consolidate the scientific basis for their traditional uses. The study was carried out against two Gram-positive and two Gram-negative bacteria together with two fungi. The extracts and fractions showed mean inhibition zones diameter in the range of 10.97-14.98 mm with minimum inhibitory concentration values ranging between 39.06 and 625 µg/mL against the susceptible bacteria and fungi. The ethyl acetate fraction of B. luridum exhibited notable activity against Staphylococcus aureus while the total extract showed moderate activity against Salmonella typhi. Regarding B. rupestris, the total extract, n-hexane and ethyl acetate fractions showed moderate activity against Escherichia coli, Candida albicans, and Salmonella typhi, respectively. Other extracts and fractions showed weak or no activity against the tested microorganisms. Qualitative phytochemical screening of both plants was performed to preliminary unveil the classes of secondary metabolites present in the leaves. The results indicated the existence of flavonoids, tannins, sterols, triterpenes, carbohydrates and/or glycosides in both plants.
