Millettia pachycarpa (synonym M. taiwaniana Hayata ) is a perennial climbing shrub belonging to the genus Millettia. It is one of the most well known among ~150 species of Millettia, as it is widely used in traditional practices, such as for poisoning fish, agricultural pesticide, blood tonic, and treatments of cancer and infertility. The bark fiber is used for making strong ropes.

It is endemic to south-east Asian region including Bangladesh, Bhutan, China, India, Myanmar, Nepal, Taiwan, Thailand and Vietnam. In India it is found only in the eastern region such as Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland, Sikkim, Tripura and West Bengal.

Description

M. pachycarpa is a climbing shrub. It has dark brown inflated legumes that are densely covered with rough pale yellow warts. The leguminous pods contain 1-5 dark brown reniform seeds. The leaves have 13-17 papery leaflets and the flowers are lilac-colored. Leaves 13-17-foliolate; rachis 30–50 cm, including petiole 7–9 cm; leaflet blades elliptic-oblong to lanceolate-oblong, base cuneate to rounded, apex acute. Legume dark brown, oblong or when 1-seeded ovoid, inflated, densely covered with pale yellow warts. Pseudora cemes with 2-6 branches beneath new stems, 15–30 cm, brown tomentose; rachis nodes with 2-5 flowers clustered on a 1–3 mm spur.

Chemical constituents

A number of bio-active chemicals in has been reported from M. pachycarpa including several prenylated flavonoids, dihydroflanonol and chalconoids from the seed,[1] rotenoids such as rotenone, cis-12a-hydroxyretenone, rot-2′-enonic acid and cis-12a-hydroxyrot-2′-enonic acid from the root,[2][3] and barbigerone.[4] Several chemical analyses have yielded a number of novel prenylated isoflavones including erysenegalensein E, euchrenone b10, isoerysenegalensein E, 6,8-diprenylorobol, furowanin A and B, millewanins-F, -G and -H, warangalone, and auriculasin from the leaves.[5][6] The major flavonoid component of the stem was found to be auriculasin (6).[7] In addition terpenoids such as epifriedinol and friedelin, and steroids (phytosterols) such as campesterol, β-sitosterol and stigmasterol are also identified from the stem and leaf.[8]

Traditional uses

Fish poison

Among the tribal natives of north-east India and Tsou people of Taiwan, the juice extract of the crushed root and seed are widely used as fish poison in traditional fishing; and hence the common name 'fish poison climber'.[9][10][11][12] The natives smash the plant parts against rocks, and let the juice extract run into the water. Fishes are easily stupefied and subsequently paralyzed. Then they are collected by hands or nets or baskets.

Medicine

It is well known in Chinese traditional medicine as a blood tonic and to induce the growth of red blood cells,[13] as cancer therapy in a preparation called 'Jixueteng',[14][15] There are scientific evidences behind the beneficial properties on blood. For instance food products containing phytosterols are already widely used as a therapeutic dietary option to reduce plasma cholesterol and atherosclerotic risk. Phytosterols including β-sitosterol are found to be highly effective in lowering the blood cholesterol level under randomized controlled intervention trials.[16] Phytosterol supplementation of 2 g/d is recommended by the National Cholesterol Education Program to reduce LDL cholesterol, and was validated to be highly significant in increasing the total cholesterol metabolism.[17] Stigmasterol alone was shown to inhibit several pro-inflammatory and matrix degradation mediators typically involved in osteoarthritis-induced cartilage degradation.[18]

A large body of chemical analysis also strongly supports the anticancer property. Prenylated isoflavones including erysenegalensein E, isoerysenegalensein E, 6,8-diprenylorobol, furowanin A and B, millewanins-F, -G and -H, and auriculasin were all demonstrated to have significant antiestrogenic activity.[5][6] The major flavonoid of the stem, auriculasin (6), was demonstrated to exhibit significant inhibitory effect on mouse skin tumor promotion.[7] Furowanin-A, warangalone, isoerysenegalensein-E and euchrenone b10 showed significant cytotoxicity against cancer cells, specifically by inducing time-dependent apoptosis upon human leukemia HL-60 cells.[19]

Insecticide

The finely ground seeds are prepared in suspension which is widely used in Chinese traditional medicine as insecticide against insect pests.[20] A 5% water suspension of the seeds is as effective as o.1 % benzene hexachloride spray when used against the ten-spotted grape leaf-beetle, Oides decempunclata; and also more potent than phenothiazine against the fifth-instar small white butterfly, Pieris rapae.[21] The dried powder of the root are also effective against bean aphids, silkworm and Mexican bean beetle.[22] Isolation of rotenone and other rotenoids from the root leaves no doubt for its insecticidal property as these compounds are well established insecticides.[2][3]

Anthelmintic

The crushed concoction of M. pachycarpa leaves are used by some native tribals of north-east India, and the root bark is also directly eaten for treating intestinal infection. Experimental evidence revealed that the plant extract is highly effective against the tapeworm Raillietina echinobothrida.[12][23]
