Manihot curcas (Linnaeus) Crantz.

 

Shrubs or treelets, 2-5 m tall, with watery latex; bark smooth; branches glaucous-gray, glabrous, sparsely lenticellate, pith larger. Stipules small; petioles 6-18 cm; leaf blade rotund to ovate, 7-18 × 6-16 cm, papery, nitid(밝은, 광택이 있는) green and glabrous adaxially, gray-green and along nerves puberulent to glabrous abaxially, base cordate, apex acute; palmate veins 5-7. Inflorescences axillary, 6-10 cm; bracts lanceolate, 4-8 mm. Male flowers: sepals 5, ca. 4 mm, connate at base; petals oblong, green-yellow, ca. 6 mm, connate to middle, hairy inside; disk glands 5, nearly terete; stamens 10; outer 5 filaments free, inner filaments connate in lower part. Female flowers: pedicels elongate; sepals free, ca. 6 mm; petals and disk glands as in male; ovary 3-locular, glabrous; styles bifid at apex. Capsules ellipsoidal or globose, 2.5-3 cm, yellow. Seeds ellipsoidal, 1.5-2 cm, black. Fl. Sep-Oct, fr. Oct-Dec.

 

Cultivated for medicine. Fujian, Guangdong, Guangxi, Hainan, Sichuan, Taiwan, Yunnan [native to tropical America; widely introduced].

 

Jatropha curcas seeds are the source of curcas oil, a very powerful purgative(하제), also used for making candles and soap, for lighting, and as a lubricant. There is interest in the oil as a biofuel crop for areas too dry for normal crops. The bark is used as medicine for lepriasis (leprosy), itchy skin, eczema, chronic ulcers, etc.

 

 

 

Wikipedia 설명

 

Jatropha curcas is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America.[2] It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas.[3] The specific epithet, "curcas", was first used by Portuguese doc Garcia de Orta more than 400 years ago.[4] Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut.[3] In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant",[3] but it is not the same as the usual castor oil plant, Ricinus communis (they are in the same family but different subfamilies).

 

J. curcas is a semi-evergreen shrub or small tree, reaching a height of 6 metres (20 feet) or more.[2] It is resistant to a high degree of aridity, allowing it to grow in deserts.[5][6] It contains phorbol esters, which are considered toxic.[7] However, edible (non-toxic) varieties native to Mexico also exist, known by the local population as piñón manso, xuta, chuta, aishte, among others.[8][9] J. curcas also contains compounds such as trypsin inhibitors, phytate, saponins and a type of lectin[10][11] known as curcin.[12]

 

The seeds contain 27–40% oil[13] (average: 34.4%[14]) that can be processed to produce a high-quality biodiesel fuel, usable in a standard diesel engine.[15] The oil has a very purgative property.[16] Edible (non-toxic) varieties, as those developed by selection by ethnic Mexican natives in Veracruz, can be used for animal feed and food.[17][8]

 

Description

Leaves: The leaves have significant variability in their morphology. In general, the leaves are green to pale green, alternate to subopposite, and three- to five-lobed with a spiral phyllotaxis.[18]

Flowers: male and female flowers are produced on the same inflorescence, averaging 20 male flowers to each female flower,[19] or 10 male flowers to each female flower.[20] The inflorescence can be formed in the leaf axil. Plants occasionally present hermaphroditic flowers.[18]

Fruits : fruits are produced in winter, or there may be several crops during the year if soil moisture is good and temperatures are sufficiently high. Most fruit production is concentrated from midsummer to late fall with variations in production peaks where some plants have two or three harvests and some produce continuously through the season.[18]

Seeds: the seeds are mature when the capsule changes from green to yellow. The seeds contain around 20% saturated fatty acids and 80% unsaturated fatty acids, and they yield 25–40% oil by weight. In addition, the seeds contain other chemical compounds, such as saccharose, raffinose, stachyose, glucose, fructose, galactose, and protein. The oil is largely made up of oleic and linoleic acids. Furthermore, the plant also contains curcasin, arachidic, myristic, palmitic, and stearic acids and curcin.[18]

Genome: the whole genome was sequenced by Kazusa DNA Research Institute, Chiba Japan in October 2010.[21]
