Bauhinia purpurea is a species of flowering plant in the family Fabaceae, native to South China (which includes Hong Kong) and Southeast Asia. Common names include orchid tree, Hong Kong orchid tree, purple bauhinia, camel's foot, butterfly tree, and Hawaiian orchid tree.
Bauhinia purpurea is a small to medium-size deciduous tree growing to 17 feet (5.2 m) tall. The leaves are 10–20 centimetres (3.9–7.9 in) long and broad, rounded, and bilobed at the base and apex. The flowers are conspicuous, pink, and fragrant, with five petals. The fruit is a pod 30 centimetres (12 in) long, containing 12 to 16 seeds. Leaves are alternate.
Bauhinia purpurea may possess antibacterial, antidiabetic, analgesic, anti-inflammatory, anti-diarrheal, anticancerous, nephroprotective, and thyroid hormone-regulating activity. Water extracts of the leaves of Bauhinia purpurea have been shown to have anti-ulcer activity in animals in the 'ethanol-induced gastric ulcer model'. Water extracts did not show any signs of toxicity when given to rats orally at doses up to 5000 mg/kg.
A wide range of chemical compounds have been isolated from Bauhinia purpurea including 5,6-dihydroxy-7-methoxyflavone 6-O-β-D-xylopyranoside, bis [3',4'-dihydroxy-6-methoxy-7,8-furano-5',6'-mono-methylalloxy]-5-C-5-biflavonyl and (4'-hydroxy-7-methyl 3-C-α-L-rhamnopyranosyl)-5-C-5-(4'-hydroxy-7-methyl-3-C-α-D-glucopyranosyl) bioflavonoid, bibenzyls, dibenzoxepins, mixture of phytol fatty esters, lutein, β-sitosterol, isoquercitin and astragalin.
