conclusions further investigations are needed about favorable composition of unsaturated fatty acids and flavonoid content of leaves of s. paradoxa. in addition, due to high phenolic content of the leaves, s. paradoxa is a promising source of natural antioxidants and may play good antidiabetic activity. results the amount of total phenolic compounds was higher in leaves than roots. besides, roo...

A collection of tannins extracted from various plant species was subjected to thermally assisted hydrolysis and methylation (THM) using tetramethylammonium hydroxide. The products obtained included 1,3,5-trimethoxybenzenes, derived from A rings of condensed tannins (CTs), and 1,2-dimethoxybenzene, 1,2,3-trimethoxybenzene, and derivatives as major products from the B ring. 1,2,4-Tri- and two tet...
