Opinion on Stevia Rebaudiana Bertoni plants and leaves

Antidiabetic activity and phytochemical screening of crude extract of Stevia rebaudiana in alloxan-induced diabetic rats

BACKGROUND Stevia rebaudiana regulates blood sugar, prevents hypertension and tooth decay. Other studies have shown that it has antibacterial as well as antiviral property. METHODS Preliminary phytochemical screening of aqueous, ether and methanolic extracts of S. rebaudiana was done. Acute and sub-acute toxicity were conducted on twenty four Albino rats, divided into one control (Group I) an...

Antibacterial, Preliminary Phytochemical and Pharmacognostical Screening on the Leaves of Vicoa indica (L.)DC.

The aim of the present research was focused on the antibacterial, preliminary phytochemical and pharmacognostical properties of Vicoa indica (L.)DC. via in vitro approach. The aqueous and organic solvent (hexane, chloroform and methanol) extracts from the leaves of Vicoa indica (Asteraceae) were tested against Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Vibrio parahaemolyt...

Identification of Stevioside Using Tissue Culture-Derived Stevia (Stevia rebaudiana) Leaves

Stevioside is a natural sweetener from Stevia leaf, which is 300 times sweeter than sugar. It helps to reduce blood sugar levels dramatically and thus can be of benefit to diabetic people. Tissue culture is a very potential modern technology that can be used in large-scale disease-free stevia production throughout the year. We successfully produced stevia plant through in vitro culture for iden...
