Phenolic contents and bioactivities of pericarp and seeds of Pleiogynium solandri (Benth.) Engl. (Anacardiaceae)
Objective(s): This study aimed to develop drugs from natural sources to overcome the side effects of many of synthetic drugs. Methanol extracts of both pericarp and seeds of Pleiogynium solandri were used to investigate antioxidant, hepatoprotective, and renal function protective, analgesic, and anti-inflammatory effects and to determine the chemical composition of the extract responsible for b...
متن کاملPhotosynthetic units of sun and shade plants.
A computer analysis of fluorescence induction curves of leaves treated with 3-(3,4-dichlorophenyl)-1,1 dimethylurea was done for several species. These measurements gave the ratios of the total chlorophyll to photosystem II reaction centers. This communication is a preliminary survey of sun and shade plants and demonstrates a significant variation in this ratio. In the sun plants, the photosynt...
متن کاملPhotosynthetic Rates of Sun versus Shade Leaves of Hyptis emoryi Torr.
Leaves on a bush of Hyptis emoryi Torr. varied in length from less than 1 cm when development occurred in full sunlight (e.g. 40 Mjoules m(-2)) to over 7 cm when the total daily solar irradiance was less than 3 Mjoules m(-2). The 1-cm sun leaves were 3-fold higher than the 7-cm shade leaves in chlorophyll per unit area, mesophyll thickness, and the internal to external leaf area ratio (A(mes)/A...
متن کاملChemical Analysis and Evaluation of Antioxidant, Antimicrobial, and Photoprotective Activities of Schinopsis brasiliensis Engl. (Anacardiaceae)
Schinopsis brasiliensis Engl. is a native plant of Caatinga which has high concentrations of compounds capable of absorbing ultraviolet light, suggesting its potential application for the development of sunscreen preparations. After its identification and collection, this vegetable drug was submitted to a physicochemical analysis through the preparation of ethanolic extract. The phytochemical s...
