Composition of the coagulant polysaccharide fraction from Strychnos potatorum seeds

Potato Starch as a Coagulant for Dye Removal from Textile Wastewater

“…In addition, the use of natural coagulants for textile wastewater treatment has also been emphasized and encouraged as a viable alternative owing to its ecofriendly nature. The polysaccharide extracted from Strychnos potatorum (Nirmali) seeds has been reported to reduce the 80 % turbidity of kaolin solution (Adinolfi et al 1994). The seed of Moringa oleifera, known as the drumstick tree, is also used as coagulant and/or flocculants in the water and wastewater treatment.…”

Antidiabetic and Antihyperlipidemic Activities of Methanolic Leaf Extract of <i>Stephania japonica</i> in Alloxan Induced Diabetic Rats

“…The plant Stephania japonica have been claimed to possess various medicinal properties. A juice of the whole plant is employed in treatment of convulsions, skin diseases, cough, asthma like symptoms and kidney disorders [11] [12] [13] [14] [15]. S. japonica (Thunb.…”

Emerging usage of plant-based coagulants for water and wastewater treatment

“…Previous studies [16] and [21] have established that the seed extracts also contain lipids, carbohydrates and alkaloids containing the -COOH and free -OH surface groups which enhance the extracts' coagulation capability. Adinolfi et al [22] report that a mixture of polysaccharide fraction extracted from S. potatorum seeds contained galactomannan and galactan capable of reducing up to 80% turbidity of kaolin solution. In all cases, the galactomannans are made up of a main chain of 1,4-linked β-d-mannopyranosyl residues bearing terminal α-d-galactopyranosyl units linked at the 0-6 position of some mannose residues [23].…”
