Gen info
Bauhinia is a genus of more than 200 species. The genus was named after the Bauhin brothers, Swiss-French botanists. The leaves share the double-leaf configuration of a heart, or more popularly, that of a butterfly. (Also see: Alibangbang / Bauhinia malabarica)

The Hongkong orchid tree (Bauhinia blakeana is named after one of the British Governors of Hongkong, Sir Henry Blake, 1898-1903) and is now the floral emblem of Hongkong. The flower looks like an orchid, and thus has earned the name "Orchid Tree." It is usually sterile, and debated as of hybrid origin between Bauhinia variegata and Bauhinia purpurea.

Botany
Bauhinia purpurea is a small to medium-sized deciduous fast-growing tree or shrub. Crown is round, symmetrical, moderately dense. Bark is pale grey, smooth to slightly fissured and scaly. Young branches are glabrous or glabrescent. Twigs are slender, light green, slightly hairy, and angled. Heartwood is brown, hard, and durable. Leaves are simple, alternate, base rounded to shallow-cordate, up to 12 centimeters long and wide, deeply 2-lobed at the apex. Inflorescences are 6- to 10-flowered raceme in terminal panicles. Flowers are showy and fragrant, numerous, hypanthium, turbinate, purple, nearly white or purple-marked. Fruit is brown, strap-shaped, about 15 to 20 centimeters long, 1.5 to 2.5 centimeters wide, with 10 to 15 shiny brown, glabrous, dehiscent, rounded, flat seeds, twisting as it opens. Seeds are orbicular, 14 to 16 millimeters in diameter, 1 to 2 millimeters thick. (17)

Botanically, very similar to and often confused with B. variegata but the petals are narrower, oblanceolate, and do not overlap. Stamens are 3 to 4.

Studies
Anti-Inflammatory / Antipyretic / Antinociceptive:
Study of aqueous extract on animal models showed antinociceptive, antipyretic and anti-inflammatory activities. (1)
Nephroprotective: Study showed the unripe pods and ethanol extract of leaves of BP significantly protected rat kidneys from gentamicin-induced histopathological changes, with normalization of gentamicin-induced increases in serum creatinine, uric acid and BUN. (4)
Wound Healing: Study of methanol and chloroform extracts prepared in carbopol and simple ointment base and applied to wounds showed dose-dependent and significant reduction in epithelization and wound contraction time. The methanol extract exhibited more activity. Results indicated BP leaves had wound healing property. (5)
Antiproliferative / Antioxidant: Study showed Bauhinia purpurea leaf possesses potential antiproliferative and concentration-dependent antioxidant activities. (6)
Antioxidant: Study of different extracts bark and leaves of B. purpurea showed significant inhibition of superoxide radicals in a dose-dependent manner. (7)
Seed Oil: Extracted oil showed a reasonable ration of saturated and unsaturated acids. After oil extraction, the seed residue presents as a source of protein in the manufacture of poultry and animal feeds. (9)
Anti-Ulcer / Leaves: Aqueous extract of BP leaves exhibited antiulcer activity which could be due to the presence of saponins or sugar-free polyphenols. (10)
Antihyperlipidemic / Antiatherogenic: Study showed BP extracts significantly suppressed a cholesterol-high fat diet-induced hyperlipidemia in rats, suggesting antihyperlipidemic and anthiatherogenic potential.
The activity may be due to polyphenolic compounds flavonoids, tannins, and proanthocyanidines. (11)
Bauhiniastatins / Cancer Cell Growth Inhibitors: Study isolated four cancer cell growth inhibitors designated Bauhiniastatins 1-4 and pacharin. Bauhiniastatin 1 exhibited significant growth inhibition of P388 cancer cell line. (12)
Antilipidemic / Anti-Obesity: Study of methanolic extract showed significant decreases in serum triglycerides, total cholesterol and LDL, with significant increases in HDL in obese rats. The body weight of the HFD induced obese rats was reduced by 30% when administered with sibutramine. The antilipidemic effect of MEBP was found to be more effective than Sibutramine. (13)
Hepatoprotective / Paracetamol Induced Toxicity: Study investigated the hepatoprotective potential of a methanol extract of Bauhinia purpurea leaves in paracetamol-induced liver toxicity in rats. Results showed potential hepatoprotective activity attributed to its antioxidant activity and high phenolic content. (14)
Comparative Antioxidant Activity of Different Parts of B. purpurea: Study investigated the antioxidant activity of various extracts of leaves and bark of B. purpurea using DPPH and NO scavenging capacity. All extracts showed potent antioxidant capacity. The ethyl acetate bark extract showed highest activity in DPPH assay. An EA extract of leaves showed highest activity in in NO scavenging activity. (15)
Antioxidant / Flowers: Study investigated the antioxidant activity of Bauhinia purpurea flowers. Results showed free radical scavenging activity, in decreasing order of activities: nitric oxide scavenging —reducing power activity—total antioxidant activity—metal chelating activity. (16)
Antidiabetic / Stem Bark: Study i
nvestigated various extracts of stem bark of Bauhinia purpurea for antidiabetic activity in alloxan-induced diabetic mice. At higher doses, the extracts showed significant antidiabetic activity, with significant P values. The methanol extract showed the most potent antidiabetic activity. (18 )
Antimicrobial / Stem Bark: Study screened an n-hexane extract of stem bark for phytochemicals and antimicrobial activity. Phytochemical screening yielded fatty acids, triterpenoids, steroids, alkaloids and phytol esters. Extract showed antimicrobial activity against all 6 bacterial strains (B. subtilis, E. coli, P. aeruginosa, S. typhimurium, Klebsiella spp) and 2 fungal strains (A. niger and Claviceps purpurea). (19 )
Anthelmintic / Stem Bark / Whole Plant: Study evaluated petroleum ether and aqueous extracts of stem bark of BP against Indian earthworm Pheretima posthuma. The petroleum ether extract significantly demonstrated paralysis, and also death in shorter time compared to reference drug piperazine citrate. (20) Study evaluated aqueous and ethanolic extracts of whole plant of Bauhinia purpurea for anthelmintic activity against Pheretima posthuma. Both extracts exhibited significant anthelmintic activity at highest concentration of 100 mg/ml. Piperazine citrate was the standard reference drug. (31)
Cytotoxic Activity / Leaves and Bark: Study evaluated different plant parts for cytotoxic activity using brine shrimp lethality bioassay. Results showed all extracts of both leaves and bark showed promising cytotoxic activity, the highest in the methanol bark extract and n-hexane fractions of leaves. Results suggest a promising source for novel anticancer agents. (21)
Antidiabetic Activity: Study evaluated ethanol extracts of various plant parts (stem, root, leaf, and flowers) for anti-diabetic activity in diabetic Wistar rats induced by intraperitoneal STZ injection. All the extracts exhibited significant antidiabetic activity—the methanol extract was most active. (23)
Anti-Obesity Effect: Study evaluated the effects of an ethanolic extract of BP on parameters of body weight, lean mass, fat free mass fat percent, tissue and plasma lipid profile, plasma glucose, insulin, and insulin resistance, and activity on amylase, lipase, leptin and adiponectin levels in high calorie diet induced obese rats. Results suggest EEB suppresses high-calorie-diet-induced obesity, with a potential for treatment of obesity and associated complications. (24)
• Antimicrobial / Leaves: Study evaluated the antibacterial and antifungal activities of B. purpurea leaves against B. subtilis, S. aureus, S. typhi, E. coli, P. aeruginosa, and C. albicans. Antimicrobial activity occurred in a concentration dependent manner. The efficacy was less than standard antibiotic, tetracycline. The antibiotic activity might be attributable to synergism between flavonoids, hydroxy acids and sesquiterpenes. (see constituents above) (26)
• Anti-Ulcer / Acute Toxicity Testing / Leaves: Study evaluated the anti-ulcer activity of methanol extract of B. purpurea leaf. Oral administration showed anti-ulcer activity (p<0.05) in all models tested. A dose-dependent protection was noted in the indomethacin-induced gastric ulcer model. In pyloric ligation assay, the extract significant increased gastric wall mucus secretion. In oral acute toxicity testing, 5000/mg/kg did not cause signs of toxicity in rats. (27)
• Amelioration of Hyperthyroidsim in LT4 Induced Albino female rats: Study evaluates the possible ameliorative effect in the regulation of hyperthyroidism in an albino wistar rat model. Results showed simultaneous administration of BP extract to LT-induced hyperthyroid animals reversed all effects indicating potential in the regulation of hyperthyroidism. Efficacy appears to be comparable to that of propylthiouracil (PTU) a standard antithyroidic drug. (28)
• Bioactive Compounds / Antimalarial, Antimycobacterial, Antifungal, Anti-Inflammatory, Cytotoxic / Roots: Study of root extract isolated eleven new secondary metabolites. Study reported antimycobacterial, antimalarial, antifungal, cytotoxic, and anti-inflammatory activities of the isolated compounds and discussed their biosynthetic pathways. (see constituents above) (32)
• Antidiabetic / Leaves: Study evaluated a methanolic leaf extract of B. purpurea in STZ-induced diabetic rat model. Results showed dose-dependent antidiabetic activity with significant (p<0.01) reduction in blood glucose levels. The activity was postulated to be due to an increase in pancreatic beta cell function or inhibition of intestinal glucose absorption. (33)
• Anti-Inflammatory / Antioxidant / Bark: Study evaluated the anti-inflammatory and antioxidant efficacy of ethanolic extract of B. purpurea bark in Sprague-Dawley rats. Results showed significant and dose-dependent inhibition of paw edema and ear edema and reversal of hematologic alterations to near normal. DPPH assay and MDA measurements showed potent antioxidant activity of the bark extract. Acute toxicity study showed the extract's non toxic nature even at higher doses. (34)
• Corrosion Inhibition: Study evaluated the inhibitory effect of B. purpurea extract in the corrosion of carbon steel in sulfuric acid solution. Results showed reasonable inhibitory effect. Study suggests the flavonoids in the leaf extract are potential corrosion inhibitors. The compound, rutin, exhibited a protective effect in HCl medium. (35)
• Antiepileptic / Stem Bark: Study evaluated an ethanol extract of B. purpurea stem bark for antiepileptic activity in Swiss albino mice by MES and PTZ methods. Results showed antiepiletic activity as evidenced by reduction in duration of all phases of epilepsy viz., flexion, extensor, convulsion, and stupor phases. (36)
• Unique Chimeric Lectin: Lectins are carbohydrate-binding proteins used in biochemical, immunochemical, and histochemical studies. Bauhinia purpurea lectin (BPA) is a leguminous lectin with affinity for galactose and lactose. Study showed a novel type of lectin with unique carbohydrate-binding specificity can be constructed from BPA. (37)
• Cytoprotective Against Ethanol Induced Gastric Mucosal Ulcers / Leaves: Study evaluated the protective effect of ethanolic extracts of B. purpurea leaves against absolute ethanol-induced gastric mucosal damage in experimental rats. Results showed significant gastric mucosal protection as evidenced by gross reduction in ulcer area, increase gastric mucus production and decreased acidity of gastric content, together with histological evidence of decreased mucosal damage, reduction of edema and leucocyte infiltration. (39)
• Attenuation of Depression / Leaves: Study evaluated the antidepressant activity of ethanolic extract of leaves in Swiss albino mice using Forced swim test, Tail suspension test, and duration of mobility and immobility. Results showed statistically significant decrease in immobility time in both models. (40)
• Amelioration of Cisplatin-Induced Nephrotoxicity / Pods and Bark: Study of ethanolic extract of B. purpurea unripe pods and bark showed nephroprotective activity against cisplatin-induced nephrotoxicity in adult albino rats. (41)
