– Fixed oil, 33%; with triolein 87.7 %, triplamitin, 8.41 %, tristearin 3.89%, an alkaloid, a bitter principle and a glycoside, samaderin.
– The wood contains a bitter principle similar to quassin.
– Bark is toxic with a bitter principle, as do the seeds.
– Bitterness attributed to flavanoids like quassinoids.
– Bark and wood considered febrifuge, tonic, stomachic and emmenagogue.
– Roots and fruits considered stomachic.
– Studies suggest antitumor, antifeedant, antiviral, anthelmintic, antioxidant, antimicrobial properties.
– Leaves reported termiticidal.
Parts used and preparation
Seeds, bark, and wood.
– Mixture of the powdered bark or wood scrapings in warm water or coconut oil used for fever.
– For rheumatism, seed is roasted, pounded, and applied over affected area.
– Leaves are bruised and applied over skin eruptions.
– Juice from pounded bark also used for skin diseases.
– Oil extracted from fruit kernels used for rheumatism.
– Seeds worn around the neck for asthma prevention.
– Seeds used as emetic and purgative.
– Infusion of wood taken as a tonic, as a substitute for Quassia.
– Infusion of leaves used as insecticide, especially against white ants.
– In the Congo and Madagascar, used for malaria.
– In Ayurveda, Samadera indica pacifies vitiated vata, kapha, arthritis, edema, itching skin diseases, constipation, and general debility.
• Antiinflammatory / Antimalarial / Cytotoxicity: Study on stems yielded four new quassinoids named samaderines X, Y, and Z, and indaquassin X, and a new C19 quassinoid glycoside, 2-O-glucosylsamaderine C, together with five known quassinoids, samaderines B, C, and E, indaquassin C, and simarinolide. Some of the compounds exhibited significant growth-inhibitory activity against cultured Plasmodium falcifarum. Compounds 1-8 exhibited in vitro toxicity against KB cells.
• Quassinoids: Quassinoids possess a wide spectrum of biological activities. Reports have been made of its antimalarial, antiinflammatory and antiviral properties and two studies have been published on quassinoids antitumor activity, but thus far the compounds have been found to be too toxic for clinical use.
• Quassinoids / Antifeedant: Study of the seeds and bark of Samadera indica yielded four quassinoids: indaquassin C, samaderins C, B and A. Indaquassin C was the most effective antifeedant. Samaderin C increased pupal duration and induced pupal mortality.
• Mosquitocidal: Varied fractions and extracts, including Samadera indica leaf extracts significantly decreased the fecundity of mosquitoes and the hatchability of their eggs of C quinquefasciatus, A stephensi and Aedes aegypti.
• Antibacterial: Study results indicated antibacterial activity, especially towards a single pathogen, Pseudomonas aeruginosa. Phytochemical screening yielded flavonoids, phenols and steroid.
• Toxicopathology: Study evaluated evaluated the toxicopathology effect of gatep pahit stem extract fractionation of various extracts on mice liver and kidney at 100 mg kbw. Q. indica chloroform extract has the lowest level of damage to hepatocytes while hexane fraction caused the least damage in kidney tubular epithelium. The ethyl acetate showed the most epithelial damage.
• Antimicrobial Topical Herbal Formulations: Study evaluated the toxicity of a methanolic extract of Samadera indica Gaertn. and its suitability for use in herbal formulations. The in-vitro antimicrobial study of the formulated ointment showed significantly strong activity against S. aureus, P. aeurginosa and C. albicans. Results suggest the formulated ointment and gell are safe and efficient formulations for topical delivery.
• Antimicrobial / Antioxidant: Study evaluated the antioxidant and antimicrobial activity of methanolic extracts. Results showed significant activity against gram positive, gram negative bacteria, and Candida albicans. Antioxidant testing showed increased scavenging activity in a dose-dependent manner.
• Polyherbal Antiseptic Ointment: An ointment, formulated using methanolic extracts of Azaridachta indica, Chromolaena odorata, Mimosa pudica, and Samadera indica, was evaluated for antibacterial and antioxidant activity. Results showed concentration-dependent increase in scavenging activity, the effect attributed to flavanoids and tannins. Antibacterial testing showed wound healing activity. Overall study showed an effective polyherbal antiseptic ointment.
• Anthelmintic: Study of alcoholic and aqueous extracts from leaves were evaluated for anthelmintic activity against Rallietina spiralis and Ascaridia galli. The extracts showed significant dose dependent anthelmintic activity.
• Antioxidant: Study evaluated various extract for antioxidant activity using DPPH, ABTS radical scavenging assay, FRAP, and DCF/AAPH assay. All methods showed prominent antioxidant activity although comparatively lower than standard Quercetin.
• Anti-inflammatory Activity: Study evaluated the anti-inflammatory activity of various Samadera indica by HRBC membrane stabilization. An ethanolic extract of S. indica showed significant anti-inflammatory activity. Diclofenac was used as standard.
