Bioactive Analysis of Auricularia Delicata: Extraction, Purification, and Characterization of Polysaccharides from Auricularia Delicata-Morocco Forest
(Academia, 2020)Auricularia mushrooms are bioactive compounds which are mostly polysaccharides. Many studies have shown the use of Auricularia from wild mushroom for medicinal purposes such as antioxidant, antidiabetic, antitumor, ... -
Bioactive carbazole alkaloids from Alysicarpus ovalifolius (Schumach)
(The Korean Society for Applied Biological Chemistry, 2015-12-01)Phytochemical and biological evaluation of the stem bark of Alysicarpus ovalifolius led to the isolation of three carbazole alkaloids identified as mohanimbine (1), koenimbine (2) and koenidine (3) along with quercetin ... -
Bioactivity of Endophytes from Calliandra calothyrsus, Leucaena diversifolia and Sesbania sesban Against Cercospora zeae-maydis
(International Journal of Research and Scientific Innovation, 2020)Endophytes are microorganisms that accomplish parts of their life cycle within living host tissues without causing apparent damage to the plants. Endophytes confer survival advantage to the plant as they play a role in ... -
Bioavailability assessment of hexachlorobenzene in soil as affected by wheat straw biochar
(Elsevier, 2012-05-30)Biochar incorporation with soil could increase sorption of organic contaminants, thereby reducing their bioavailability. In this study, the effects of wheat straw biochar on the sorption, dissipation and bioavailability ... -
