• Phytochemicals: Study of roots and stems of Tabernaemontana divaricata isolated six compounds: bis
(2, 3-dihydroxypropyl) octacosanedioate, tetratriacontanol, palmitic acid, glycerol monopalmitate, ß-sitosterol and ß-daucosterol.
• Acethylcholinesterase Inhibitory Effect / Alzheimer Disease: Study demonstrated the T. divaricata extract could be beneficial in slowing the process of memory loss with additional benefits on learning and memory process. Results suggest TDE could be used to develop a new acetylcholinesterase inhibitor for the treatment of Alzheimer’s disease.
• Reversible Acethylcholinesterase Inhibitory Effect: Study showed T. divaricata extract is a reversible AChE-inhibitor and could be beneficial as a novel therapeutic agent for AD.
• Decreased Acethylcholinesterase Activity / Alzheimers: Study suggests subchronic administration of TDE might prevent beta 25-35 peptides-induced memory deficits by decreasing the AChE activity level. It presents a potential nootropic supplement for elderly people with Alzheimer’s dementia.
• Cholinergic Alkaloids: At least 66 alkaloids have been isolated from T. divaricata. Possible cholinergic candidate alkaloids are: coronaridine, voacangine, isovoacristine, (19,20) dihydrotabemamine, and (19,20) dihydroervahanine A.
• Anti-Fertility: Study of ethanolic extracts of TD leaves on immature female rats exhibited oestrogenic activity. Enhanced uterine weight and increase in luminal epithelium height and histological changes suggest the TDE may be useful in anti-fertility therapy.
• Antioxidant / Anti-Inflammatory / Flowers: Study of the ethanol extract of T. coronaria flowersshowed anti-inflammatory activity attributed to its free radical scavenging properties.
• Gastroprotective: Study investigated the anti-ulcer property of T. divaricata flower methanolic extract. Results showed remarkable gastroprotective effect with significant decrease in volume of gastric juice, free and total acidities and ulcer index.
• Antidiabetic / Cytotoxic: Study investigated the antidiabetic activity of a methanol extract of flowers on alloxan-induced diabetic mouse model. Results showed antihyperglycemic effect and low cytotoxicity may provide new molecules for the treatment of diabetes.
• Antimicrobial / Antioxidant: Study investigated the biologic activities of stem extracts. Results showed antimicrobial, anti-inflammatory and antioxidant effects. A crude ethanol extract exhibited inhibition of gram positive and gram negative bacteria, especially Staphylococcus aureus. An ethyl acetate fraction showed the highest antioxidant activities.
• Antinociceptive: Crude ethanol extract of leaves of T. divaricata produced significant writhing inhibition i acetic acid-induced mice model.
• Antioxidant / Flowers and Leaves: Study evaluated the antioxidant activity of flower and leaves of Td. Results showed significant antioxidant activity.
• Anticonvulsant: An alcoholic extract of flowers of Td tested in animal models showed anticonvulsant property with decreased duration of tonic extensor phase. Results lend pharmacologic credence to the plant’s folkloric and ethnomedical use in the treatment of epilepsy.
• Cytotoxic / Antioxidant: A methanolic extract of leaves showed potent dose-dependent antioxidant property in all antioxidant assays. The extract also showed significant cytotoxic effect suggesting the presence of potent bioactive principles with a potential for antiproliferative, antitumor, and pesticidal applications.
• Anxiolytic: Study evaluated the anxiolytic activity of alcoholic extract of Tabernaemontana divaricata on mice models using EPM (Elevated Plus Maze), OFT (Open-Field Test) and LDT (Light-Dark Transition) tests. Results showed significant anxiolytic activity attributed to the presence of alkaloids, flavonoids and other constituents.
• Antidiabetic / Cytotoxic: Study evaluated the antidiabetic activity of a methanol extract of leaves of T. divaricata leaves on alloxan induced diabetic mouse model. The extract was also subjected to Brine shrimp lethality assay. Results showed T. divaricata has potential antidiabetic activity and low toxicity.
• Antibacterial / Bovine Mastitis: Study of dried leaves yielded steroids, tannins, saponins, gums, and reducing sugar. It was evaluated for antibacterial activity against causative organisms of Bovine Mastitis. Ethanol, methanol and aqueous extracts showed maximum potency against infectious pathogens S. aureus, Coagulase negative Staph aureus Streptococcus agalactae, Strep uberis and E. coli.
• Analgesic / Anti-Inflammatory / Flowers: Study of an ethanolic extract of T. divaricata flowers showed analgesic and anti-inflammatory effects on a Wistar rat model.
• Antiulcerogenic / Prostaglandin Analogous and Antioxidant / Flowers: Study evaluated the antiulcerogenic effect of a methanolic extract of T. divaricata flowers in aspirin and ethanol induced gastric ulcers. All three test doses exhibited gastroprotective function, with the higher doses being more effective, probably through antioxidant mechanism and enhancement of gastric mucus production.
• Antibacterial / Leaves: Study of various extracts of dried leaves showed maximum potency against infectious pathogens viz Staphylococcus saprophyticus, S. aureus, S. pyogenes, Enterococcus faecalis,Salmonella typhi, E coli, Shigella boydii, S. dysenteriae, and Pseudomonas aeruginosa.
• Anthelmintic / Leaves: Study evaluated fresh and dried flower extracts for anthelmintic activity using Indian earth worms. Results showed anthelmintic activity at various concentrations compared with standard drug Metronidazole.
• Anti-Obesity / Leaves: Study evaluated the potential effect of a methanol extract of aerial parts of T. divaricata on obesity and hyperlipidemia on atherogenic diet induced obese rats. Results showed Td exerted significant anti-obesity and anti-hyperlipidemic effects in rats fed an atherogenic diet.
