For first time, essential oils (EOS) obtained by hydrodistillation from dried flowers, were analyzed GC/MS SPME-GC/MS describe their volatile chemical profile. Differences qualitative quantitative composition between two violets have been found. A total of 43 compounds identified amo...

natural substances extracted from plants have recently been considered as potential sunscreen resources because of their ultraviolet ray absorption in the uva region and their antioxidant activity. in the present study, the uv protective effects of ethyl acetate extracts of some common medicinal plants, which have flavonoids and other phenolics as the most important components, were evaluated u...

Cyclotides are a large family of plant peptides that are structurally defined by their cyclic backbone and a trifecta of disulfide bonds, collectively known as the cyclic cystine knot (CCK) motif. Structurally similar cyclotides have been isolated from plants within the Rubiaceae, Violaceae, and Fabaceae families and share the CCK motif with trypsin-inhibitory knottins from a plant in the Cucur...
