Salvia tomentosa is a common medicinal plant, and it is consumed as an herbal tea in some Mediterranean countries. It has been extensively collected from its natural habitat, and careless collection has caused the recent extinction of some plants. The present study was undertaken to cultivate S. tomentosa and compare the phenolic composition and antioxidant properties of wild and cultivated plants. Total phenolics, total flavonoids, and antioxidant activity of S. tomentosa ranged between 49.27 and 66.15 mg GAE g^{-1} dry weight (dw), 36.27 and 40.83 mg catechin g^{-1} dw, and 1.77 and 2.29 mg dw mg^{-1} DPPH, respectively. Total phenolic …

Table grapes (Vitis vinifera) of the cultivar Shahroudi were coated with 0.5% or 1% chitosan and then stored at 0 °C for 60 days. Shelf-life qualitative traits including rachis and berry appearance and berry cracking, shattering, decay, browning, acceptability, and flavor were evaluated. Treated berries showed less weight loss, decay, browning, shattering, and cracking. Flavor-related factors such as total soluble solids (TSS), titratable acidity (TA), and TSS/TA ratio levels were higher in treated fruits; however, there was no significant difference between the fruits treated with 0.5% and 1% chitosan. Changes of the total phenolics, catechin, and antioxidant capacity of the …

Hypericum triquetrifolium is a promising medicinal plant from eastern Europe and the Mediterranean area. The present study was conducted to determine ontogenetic and morphogenetic variation of chlorogenic acid, rutin, hyperoside, isoquercetin, quercitrin, and quercetin content in this species. The wild-growing and greenhouse-grown plants were harvested at vegetative, floral budding, full flowering, fresh fruiting, and mature fruiting stages and were dissected into stem, leaf, and reproductive tissues, which were dried separately and subsequently assayed for bioactive compounds by high performance liquid chromatography. Chemical contents in whole plants increased during plant phenology and, generally, higher accumulation levels were observed in wild plants. …
