Catharanthus roseus cell suspension cultures were employed for the biotransformation of (–)-caryophyllene oxide (1), and four metabolites, 15-hydroxycaryophyllene oxide (2), 4β ,5αdihydroxycaryophyll-8(13)-ene (3), 2β -hydroxycaryophyllene oxide (4), and 2-hydroxy-4,5epoxycaryophyllan-13-ol (5) were obtained. Metabolites 4 and 5 were found to be new compounds, and their structures were deduced ...

Hydrodistilled essential oil of the aerial parts of Laggera crispata (Vahl) Hepper & Wood, collected from the Kumaon region of the western Himalayas was analysed by gas chromatography and gas chromatography–mass spectrometry. Eighty constituents, accounting for 83.9 % of the total oil composition, were identified. The oil was mainly dominated by sesquiterpenoids (45.3 %) and benzenoid compounds...

Studies involving the consumption,metabolism, and elimination of terpenes by small ruminants consuming terpene-laden shrubs as well as those exploring the potential for natural products as rumen modifiers could benefit from a procedure that measures terpenes in both blood and rumen fluid and that is suitable for either serum or plasma. The objective of this study was to modify an existing proce...

Melissa officinalis is a plant of Lamiaceae family with medicinal properties which is important for its aromatic, synthetic, and secondary metabolites. The aim of this research was to study the effect of selenium on secondary metabolites and antioxidant properties of Melissa officinalis. For this purpose, an experiment was done in a completely randomized design with four repli...

Essential oils can be used as an alternative to using synthetic insecticides for pest management. Therefore, the insectistatic and insecticidal activities of the essential oil of aerial parts of Salvia ballotiflora (Lamiaceae) were tested against the fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae). The results demonstrated insecticidal and insectistatical activities against this in...

As the enzyme responsible for uric acid formation, Xanthine oxidase was considered to be a therapeutic target hyperuricemic treatment. This study carried out assess potential of caryophyllene, and its derivates usually present in natural product inhibit oxidase. The molecular docking using Autodock Tool Biovia Discovery Studio conducted visualize interaction reveal structure-activity relationsh...

the chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of a. annua was analyzed by gc and gc/ms and sixty-two components were identified. the main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). the full-flowering oil contained predominantly caryophyllene (19.4%), germacrene d...

Background:Tanacetum vulgare L. (Asteraceae) is a perennial herb that has been used to treat multiple ailments. Regional variability of the chemical composition of T. vulgare essential oils is well-known. Despite these regional chemotypes, most relevant studies did not analyze the complete chemical composition of the T. vulgare essential oil and its constituents in relation to their biological ...

Lemon balm (Melissa officinalis L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Micronutrients are necessary in low dose for the growth and the development of plants. Present research was conducted to study the effects of micronutrients including manganese (Mn) and copper (Cu) on morpho-physiological traits and essential oil of lemon balm. Fie...
