Antimalarial: Study isolated 44 casssane- and norcassane-type diterpenes. Most of the tested diterpenes showed antimalarial activity; norcaesalpinin E showed the most potent activity, more than the drug chloroquine. (1)
Antimalarial: In a study of six plants used in traditional medicine for malaria, C. bonducella and Cassia abbreviata leaf ethanol extracts were the most promising for further studies. (12)
Antioxidant: Study showed the methanolic extract of C crista has potent antioxidant activity and ROS scavenging activity as well as iron chelating property.
Radical Scavenging Activity: Ethyl acetate extract showed a maximum of 49% free radical scavenging activity at the end of 1 hr. Although it may help in diabetes-linked oxidative stress, it does not necessarily contribute to its hypoglycemic activity.

Antidiabetic / Hypoglycemic: Study showed the seed kernel of Caesalpinia bonducella has significant antidiabetic and hypoglycemic effects. Activity may be partly due to a positive effect on glycogen synthesis in the liver, skeletal muscle and heart muscle due to an insulin-like action of its constituents and partly due to stimulatory action on insulin release. (3)
Antidiabetic / Seed Extracts: Study of ethanolic and aqueous extracts showed significant blood sugar lowering effect of C. bonducella in the type 2 diabetic model. (7)
Oral Antidiabetic Activity / Seed Extracts: Study of aqueous extract of C. bonducella seed shell showed very significant blood sugar lowering in glucose loaded, STZ and alloxan diabetic models. (4)
Antidiabetic: Study in STZ-induced diabetic rats showed blood sugar lowering attributed to increase of insulin release from the pancreatic cells.
Antifilarial: Study showed the C. bonducella seed kernel extract and fractions showed microfilaricidal, macrofilaricidal and female-sterilizing efficacy against L. sigmodontin and microfilaricidal and female-sterilizing efficacy against B. malayi in animal models, suggesting a potential for its use in new antifilarial drug development. (5)
Anxiolytic Activity: Study of seed extract of C. bonducella showed a significant and dose-dependent anxiolytic activity. (6)
Antitumor / Antioxidant Activity: Study of methanol extract of C. bonducella showed significant antitumor and antioxidant activity in Ehrlich ascites carcinoma (EAC)-bearing mice. (8)
Analgesic Activity: Study of flower extract of C. bonducella showed significant antinociceptive effect in the inflammatory phase of formalin-induced pain and acetic-induced parietal pain. (10)
Analgesic / Antipyretic / Anti-Inflammatory: Study showed the seed oil of C. bonducella could be a potential source of an anti-inflammatory, antipyretic and analgesic agent. (11)
Immunomodulatory: Study of the aqueous extract of C. bonducella seeds on cell mediated and humoral components of the immune system in rats produced an increase in hemagglutinating antibody titer and a change in delayed-type hypersensitivity suggesting that the extract could be a promising immunostimulatory agent. (13)
Anti-Amyloidogenic / Alzheimer’s Disease: Abeta (amyloid beta) is a major etiological factor in Alzheimer’s disease. Study showed C. crista aqueous extract could inhibit the Abeta(42) aggregation from monomers and oligomers and able to disintegrate the preformed fibrils.
Nootropic / Memory Enhancer: Study evaluated the potential of dried seed kernels of C. crista extract as a learning and memory enhancer. Results suggest CC can be beneficial in improving cognition in disorders like demential and other neurodegenerative disorders.
Antipyretic / Analgesic / Seed Kernel: Ethanolic extract of seed kernel of C. bonducella was tested for antipyretic and antinociceptive activities in adult albino rats or mice. Results showed significant central analgesic activity and marked peripheral analgesic effect. (17)
Genotoxicity Amelioration:Alcoholic extracts significantly reduced chromosomal aberration due to methyl methane sulfonate. There was also reduction of chromatid exchanges, enhancement of replication index. The extracts also reduced the number of aberrant cells and frequency of aberrations per cell in vivo. The ameliorating potential was dose and duration dependent. (18)
Anthelmintic: Various extracts of leaves of C. bonducella were investigated for anthelmintic activity against Perionyx excavates and Amplostoma caninum. All four hexane extractives showed significant death time and paralysis time. (19)
Female Reproductive System Effects / Antifertility Efficacy: Study evaluated an ethanolic seed extract on the reproductive system in Wistar female albino rats. There was significant dose-dependent decrease in the principal hormones viz. LH, FSH, estradiol, and progesterone. Results showed estrogen antagonistic effects mediated through a direct effect on the reproductive organs possibly by suppression of follicular growth in the ovary and/or disruption of hormonal balance in the hypothalamo-hypophysial ovarian and uterine axis. (20)
Anti-Convulsive: A petroleum ether extract showed anticonvulsant activity attributed to the presence of phytoconstituents such as saponins, proteins, homoisoflavone (bonducillin), carbohydrates and sterols. (21)
Sperm Effect: Study of graded doses of alcoholic seed extract of C. bonducella showed morphological changes in the sperm of albino rats. The effect can be due to general disturbances in proteins and alteration in the cauda epididymal milieu, probably due to androgen deficiency secondary to C. bonducella treatment. (22)
Hypoglycemic / Antidiabetic / Seeds: Study evaluated seed extracts for antidiabetic effect in Wistar albino male rats. Results showed reduction of blood glucose, improvement in body weight, and rejuvenation of damaged pancreas, comparing favorably with reference drug, glibenclamide. (24)
Antioxidant: Study of ethanol and methanol leaf extracts of C. bonduc showed antioxidant activity using DPPH, FRAP, superoxide radical scavenging, NO, and hydrogen peroxide scavenging assays. Its antioxidant activity may also contribute to the cytotoxic nature of the plant. (25)
Diuretic / Seeds: Study evaluated the aqueous and methanol extracts of dried seeds for diuretic effect. Results showed significant increase in urine volume, with increased excretion of sodium and potassium.(26)
Antiplasmodial / Twigs and Leaves: Ethyl acetate and petroleum ether extracts of C. bonduc showed moderate antiplasmodial activity with IC50 values of 16 and 18 µg/mL
. (27)
Hepatoprotective / Nephroprotective / Gentamicin Induced Toxicity: Study evaluated the protective effect of methanolic extract of leaves on gentamicin-induced hepatotoxicity and nephrotoxicity in rats. Results showed pretreatment significantly attenuated the physiological and histopathological alterations induced by gentamicin. (28)
Hepatoprotective / Paracetamol Induced Toxicity: Study evaluated the hepatoprotective effect of aqueous ethanolic leaf extract of C. bonduc against paracetamol induced hepatic damage in albino rats. Results showed a hepatoprotective effect which may be due to normalization of impaired membrane function activity. C. bonduc may act as a free radical scavenger of radicals involved in paracetamol metabolism by microsomal enzymes. (29)
Immunostimulating / Gluco-Arabinan / Seeds: A water-soluble gluco-arabinan (PS-II) was isolated from alkaline extract of seeds of Caesalpinia bonduc. Comparison studies of immunostimulating properties between gluco-arabinan (PS-II) and arabinan (PS-I) were carried out. (30)
Acute and Subacute Toxicity Studies / Leaves: Acute and subacute toxicity studies on ethyl acetate extract of leaves showed no toxicity at 250 mg/kbw to Swiss albino mice on behavioral, hematological, histopathological and biochemical studies. However, there was a slight change in cellular architecture in liver histology. (31)
