Phytochemical Screening, GCxGC TOF-MS Analysis and Antibacterial Properties of Crude Rhoicissus Ttomentosa Rhizome Extract

“…Some of its bioactivity include haemolytic activity and cholesterol binding property [57,58], antimicrobial, anti-protozoan, immunostimulant, anti-carcinogenic and antioxidant activities [59,60,61]. Reducing sugars act as anti-diabetics by reducing blood glucose levels [62].…”

Phytochemical Analysis of Some Selected Plants and Families in the University Botanic Garden Of Maseno, Kenya.

“…Saponins exhibit a unique property of formation of foams in aqueous solutions, cholesterol building properties, bitterness and haemolytic activity (Sodipo, Akiniyi and Ogunbamosu,2000 [30]; Okwu, 2004[31]). Plants produce saponins to fight infection by parasites (Okello, 2007) [32]and probably this could explain why this phytochemical is common among these plants.…”

Antimicrobial Activities of Crude Leaf Extract of Solanum Nigrum on Fusarium Oxysporum and Pseudomonas Syringae Cultures in Maseno (Kenya)

“…It has the property of precipitating and coagulating red blood cells. Some of the characteristics of saponins include formation of forms in aqueous solution, haemolytic activity, cholesterol binding properties and bitterness [12]; [10]. These properties bestow high medicinal activities on extract from S. nigrum.…”

“…They precipitate proteins. Tannins prevent the development and growth of microorganisms they precipitate protein and make nutritional protein unavailable to the microbes [12]. The growth of many fungi, yeasts, bacteria and viruses was inhibited by tannins [13].…”
