Study Findings
• Adaptogenic / Anti-Amnesic: Evolvulus alsinoides is used in the traditional Indian system of medicine, Ayurveda, for its memory enhancement, antiepileptic and immunomodulatory properties. Study of ethanolic extract suggested adaptogenic and anti-amnesic properties with improvement in the peripheral stress markers and scopolamine induced dementia.
• Antiulcer / Anticatatonic Activity: Study of alcoholic extract showed marked antiulcer and anticatatonic activity.
• Learning Behavior / Memory Enhancement: Study of significant reversal of amnesia induced by scopolamine. Results also showed potent memory enhancing effects.
• Anxiolytic / Antioxidant: Study showed significant reduction of neuromuscular coordination indicating muscle relaxant activity at higher doses. Results showed anxiolytic and antioxidant activities of E. alsinoides extracts and substantiates claims for use in stress-induced disorders.
• Antioxidant / Insulin Effect: Study evaluated the therapeutic effect of Evolvulus alsinoides on antioxidant activity in pancrease of experimental diabetes. Results showed effective reduction of oxidative stress induced by streptozotocin and potentially increased the insulin level. Results suggest a potential use in the management of diabetes.
• Anti-Inflammatory / Antipyretic / Antidiarrheal: Study of an ethanolic extract of whole plant in female albino rats showed anti-inflammatory effect with inhibition of carrageenan-induced paw edema, antipyretic effect with reduction of hyperpyrexia induced by Brewer’s yeast in rats, and marked anti-diarrheal activity against castor oil-induced diarrhea.
• Protective Effect on Glycoprotein Alterations in Diabetic Rats: An ethanolic extract showed a beneficial effect on glycoprotein components. Results suggest a potential use for prevention of glycoprotein mediated complications in diabetes mellitus.
• Anthelmintic / Antimicrobial: Study evaluated an ethanolic extract of e. alsinoides for anthelmintic and antimicrobial activities. Results showed the extract to be more portent than reference drug piperazine citrate with dose dependent paralysis/death of adult Indian earthworm Pheretima posthuma. Antimicrobial activity showed activity against P. aeruginosa and E coli. comparable to reference control ampicillin trihydrate.
• Lipid Effects / Antimicrobial: Study showed an ethanolic extract significantly reduced levels of triglycerides, phospholipids, cholesterol, and free fatty acids, and increased HDL. Results suggest it may be a useful supplementation for hyperlipidemia prevention in diabetes mellitus.
• Hypoglycemic Effects / Antimicrobial: Study showed a whole plant ethanolic extract has significant effect on glucose and protein metabolism, suggesting a potential use in the clinical management of diabetes mellitus.
• Cardioprotective Effects: Study evaluated possible attenuation of acute myocardial infarction in isoproterenol (ISP)-treated rat model. Results showed myocardial adaptation by augmenting endogenous antioxidants and protected rat hearts from oxidative stress associated with ISP induced myocardial injury.
• Antidyskinesial Activity: Study evaluated a methanol extract of E. alsinoides for antidyskinesial activity using acute reserpine induced dyskinesial rats. Results showed decreased transfer latency on the elevated plus maze task paradigm and reversal of reserpine induced changes in locomotor activity.
• Free Radical Scavenging Activity / Glutamate Induced Neurodegeneration: Study evaluated a whole plant extract for antioxidant activity in glutamate induced neurodegeration. Results showed E. alsinoides may be effective in treatment for various neurodegenerative diseases, possibly due to an effective free radical scavenging property.
• Gastroprotective Activity / Vishnukranti Kalka Paste: Study evaluated the gastroprotective activity of vishnukrati kalka (paste) prepared from mixing the dry powder of whole plant of Evolvulus alsinoides with cow ghee, bee honey and common sugar. Results showed strong and dose-dependent gastroprotective activity, increasing the pH of gastric juice, mucus, and carbohydrate contents. It was well tolerated without renal toxicity.
• Anti-Stress Constituents: Study isolated 2 new and 6 known compounds. Compound 1 ( 2,3,4-trihydroxy-3-methylbutyl 3-[3-hydroxy-4-(2,3,4-trihydroxy-2-methylbutoxy)-phenyl]-2-propenoate) exhibited the most promising antistress effect by normalizing hyperglycemia, plasma corticosterone, CK, and adrenal hypertrophy.
• Bactericidal Activity Against H. pylori: Study showed Evolvulus alsinoides has promising bactericidal activity against Helicobacter pylori.
• Anti-Inflammatory Activity: Study of chloroform and ethyl acetate extracts showed significant anti-inflammatory activity with carrageenan and formalin induced paw edema models in rats.
• Anticonvulsant Activity: Study of a methanolic extract suggested the presence of bioactive principles that may be beneficial in the treatment of epilepsy. Results showed dose-dependent decrease in duration of seizure.
