Patter chur/Coleus (Coleus barbatus Benth.)
1253542264image_Patterchur-Coleus out.jpg Coleus Barbatus Benth. Family - Lamiaceae Pattchur An erect profusely branched aromatic, annual up to 1.5 m high flowers are in racemes. Root well developed. REGIONAL NAMES Coleus, Makkari beru, Gundeer, Pakhan Bed and Juntiyana DISTRIBUTION Rajasthan, Maharashtra, Karnataka, Tamil Nadu and Madhya Pradesh PART USED : Root. MEDICINAL USES It is used in lowering of the blood pressure CULTIVATION AND PROPAGATION : SOIL AND CLIMATE It grows well in red sandy loam soil. A soft soil having pH 5.5-7 with low moisture contents is reported to be ideal for rich growth of plants. Plants grow well in hot, humid climate and tropical and sub tropical situation under irrigation NURSERY RAISING AND PLANTING Coleus can be grown in both ways i.e. by seeds and cuttings. The plants are best raised from stem cuttings. 10 to 12 cm long stem selected and planted in well manured nursery bed during May & June. The cuttings initiate sprouting and grow well within a month. These rooted plants are suitable for planting in the field during rainy seasons (July-August) at the distance of 20 x 20 cm. Approximately 33,600 stem cuttings are required for one acre of land. WEEDING AND HOEING Weeding and hoeing is to be done at regular interval MANURE/FERTILIZER Compost/farmyard manure (FYM) four tons/acre is required IRRIGATION Watering is necessary every third day at initial stage of transplantation. After establishment, plants are to be irrigated as and when required weekly or fortnightly. HARVESTING/POST HARVESTING OPERATION The crop matures in about 150 days after cultivation. The crop could thus be harvested during November/December. During digging of plants, roots should be lifted from the soil. After digging, the roots are cleaned and cut into small pieces so that it is convenient to dry & store. The dried roots are stored in polythene lined gunny bags. CHEMICAL CONSTITUENTS MAJOR CONSTITUENTS Forskolin OTHER CONSTITUENTS A new diterpenoid barbatusin isolated from the leaves. Cyclobutatusin isolated from the leaves. Three new labdane diterpenoids isolated from the roots. Detection of forskollin at 0.0001 % level by GLC and TLC assay. Isolation of napthopyrone is from roots. A new diterpene - barbatusol isolated. 6-b-hydroxycarnosol isolated from the plant. A new diterpenoid plectrin isolated from the plant. ACTIVE CONSTITUENTS Napthopyrone decreased the blood pressure in cats. An un-identified diterpene from the roots exhibited hyupotensive and spasmolytic activities. Coleonol lowered the blood pressure in cats and rats and also exhibited non specific spasmolytic activity on smooth muscles of GIT. Different activities exerted by forskollin were studied. Barbatusol induced lowering of the blood pressure. ANALYTICAL PROFILE The GAS-Liquid Chromtograph was equipped with a flame -ionisation detector and a 180 x 5mm glass, coil shaped column packed with 3% OV-12 on 100-120 mesh Gas Chrom Q3 .Nitrogen was the carrier gas at tow rate of 20ml/ min. and the air and hydrogen flow rates were set to maximize the detector response. A potentiometric continuous-line recorder with a speed of 300mrn/hr. was used. The temp, were; injector, 250C, column oven, 220C, and manifold, 270"C. A microsyringe was used in analysis. YIELD Approximately 600 to 1000 kg dry roots/ acre
