About 130 species of genus Anthemis occur throughout the world. Thirty-nine of them could be found in flora of Iran. According to literature, this species was not the subject of research up to now and therefore its chemical composition is not well known. However, flavonoids, polyphenolic acids, terpene and sesquiterpene compounds were reported to be the major constituents of some other species ...

The Lamiaceae family consists of a broad spectrum of medicinal plants involving Marrubium L. genus. Regarding the diverse pharmaceutical uses of the plants belonging to this genus, they can be considered as proper alternatives for chemical drugs having harmful effects. The present work aims to identify and characterize chemical compositions of the essential oils and volatiles from the aerial pa...

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...

The study evaluated the antioxidant capacity of hexane extract Canarium odontophyllum Miq. leaf; its fatty acids and terpenoids content; cytotoxic effects on UVB-induced human keratinocytes (HaCaT). FRAP assay was used to determine capacity. GC-MS analysis identify terpenoids’ in leaf. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) carried out measure keratinocytes. Serial d...

A study of the chemical composition essential oil obtained from aerial parts Salvia glutinosa L., growing in Georgia, was carried out. The percentage dominant components determined by integration, component are caryophyllene oxide (11.43 %), spathulenol (5.93 humulene (4.5 %). From terpene compounds oxygenated sesquiterpenes dominants. content phenolic  using Folin-Ciocalteu reagent aqueou...
