the hydro-distilled volatile oils, obtained from dried e ndocarp and hulls of persian bay laurel ( laurus nobilis var. angustifolia ) from laueaceae family were analyzed by gc/ms. thirteen and twelve compounds consisting 81.6% and 89.1% of the total components were identified of the oils obtained with a yield of 3% and 1.2% (w/w) respectively. differences of some compounds between endocarp and ...

As a spice and medicinal plant, Aloysia citriodora Palau (Family, Verbenaceae) is applied in nutritional and pharmacological purposes. According to the findings, many parameters relating to growth location and cultivation conditions, may affect on the secondary metabolites of the herb and result in different percentage of concerned constituents. Accordingly, present study was performed to compa...

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 ...
