Shokeen P, Anand P, Murali YK, Tandon V: Antidiabetic activity of 50% ethanolic extract of Ricinus communis and its purified fractions. Food Chem Toxicol. 2008 Nov;46(11):3458-66. Epub 2008 Aug 28.
We investigated the antidiabetic activity of 50% ethanolic extract of roots of Ricinus communis (RCRE) along with its bioassay-guided purification. Five-hundred milligram per kilogram body weight appeared to be the effective dose as it caused the maximum lowering of the fasting blood glucose, both in normal as well as type 1 diabetic animals. The maximum hypoglycemic effect was always observed at the 8th h up to which the study has been conducted. Administration of the effective dose of RCRE to the diabetic rats for 20 days showed favorable effects not only on fasting blood glucose, but also on total lipid profile and liver and kidney functions on 10th and 20th day. RCRE was purified using silica gel column chromatography. Out of several different fractions tested, only one fraction (R-18) showed significant antihyperglycemic activity. RCRE seemed to have a high margin of safety as no mortality and no statistically significant difference in alkaline phosphatase, serum bilirubin, creatinine, serum glutamate oxaloacetate transaminase, serum glutamate pyruvate transaminase and total protein was observed even after the administration of the extract at a dose of 10 g/kg b.wt. Thus R. communis seems to have a promising value for the development of a potent phytomedicine for diabetes. |
