Importance: Castor is a perennial evergreen shrub. The Sanskrit name erandah describes the property of the drug to dispel diseases. It is considered as a reputed remedy for all kinds of rheumatic affections. They are useful in gastropathy such as gulma, amadosa, constipation, inflammations, fever, ascitis, strangury, bronchitis, cough, leprosy, skin diseases, vitiated conditions of vata, colic, coxalgia and lumbago. The leaves are useful in burns, nyctalopia, strangury and for bathing and fermentation and vitiated conditions of vata, especially in rheumatoid arthritis, urodynia and arthralgia. Flowers are useful in urodynia and arthralgia and glandular tumours. Seeds are useful in dyspepsia and for preparing a poultice to treat arthralgia. The oil from seeds is a very effective purgative for all ailments caused by vata and kapha. It is also recommended for scrotocele, ascites, intermittent fever, gulma, colonitis, lumbago, coxalgia and coxitis (Warrier et al, 1996). Oil is also used for soap making. Fresh leaves are used by nursing mothers in the Canary Island as an external application to increase the flow of milk. Castor oil is an excellent solvent of pure alkaloids and as such solutions of atropine, cocaine, etc. is used in ophthalmic surgery. It is also dropped into the eye to remove the after-irritation caused by the removal of foreign bodies.

Distribution: It is a native of N. E. tropical Africa. It is found throughout India, cultivated and found wild upto 2400m.

Botany: Ricinus communis Linn. belongs to the family Euphorbiaceae. It is a monoecious evergreen shrub growing upto 4m. Leaves are alternate, palmatifid, 6-10 lobed, each 1- nerved with many lateral nerves and peltate. Lobes are lanceolate, thinly pubescent below, margin serrate and apex acuminate. Paniculate racemes are terminal with male flowers below, female ones above. Perianth is cupular, splitting into 3-5 lobes, laceolate, valvate, margin inrolled and acuminate. Filaments of stamen are connate and repeatedly branched with divergent anther cells. Sepals are 5, sub-equal, lanceolate, valvate and acute. Ovary is globose, echinate, 3-locular with 3 ovules and pendulous. Styles are 3, stout, papillose, stigmatiferous. Capsules are 3-lobed and prickly with oblong seeds having smooth testa and marbled, shiny and carunculate. R. bronze King and R. africanus are two good garden varieties which are known as Italian and East Indian Castors, respectively (Mathew, 1983, Grieve and Leyel, 1992).

Agrotechnology: Castor is cultivated both in the plains and the hills. As it has deep root system it is hardy and capable of resisting drought. It does not withstand waterlogging and frost. It requires hard dry climate for proper development of fruits and seeds. It requires a well- drained soil, preferably sandy loam or loamy sand. High soil fertility is of less importance as compared to the good physical condition of the soil. It cannot tolerate alkalinity. It is generally grown in red loamy soils, black soils and alluvial soils. The plant is seed propagated. The seed rate required is 5-12 kg/ha (pure crop) and 3 kg/ha (mixed crop). Seeds are to be sown on a hot bed early in March. When the plants come up individual plant is to be planted in a separate pot filled with light soil and plunged into a fresh hot bed. The young plants are to be kept in glass houses till early June where they are hardened and kept out. The suitable season of growing is kharif season. The crop is usually sown in April and planting is done in early July. The land is to be ploughed 2-3 times with the onset of rains and is repeated after rain. The spacing recommended is 60X90cm in case of pure crop but it is seldom cultivated pure. It is usually grown mixed with crops such as jowar, arhar, chilly, groundnut, cowpea, cotton, etc. 10-15t FYM/ha and 50kg N, 50kg P2O5 and 20kg K2O/ha will be sufficient. Addition of neem cake is beneficial as it increases oil content. There should be sufficient moisture in the field at the time of sowing. A month after planting, weeding and earthing up is to be done. The plant is attacked by hairy caterpillar, castor semi - looper, castor seed caterpillar, etc. which can be managed by integrated pest management measures. The leaf blight disease occurring in castor can be controlled by spraying with Bordeaux mixture 2-3 times at 15 days interval. Harvesting of ripe fruits can be done from the end of November till the end of February. The fruit branches are picked when they are still green to avoid splitting and scattering of the seeds. The pods are to be heaped up in the sun to dry. Then the seeds are to be beaten with stick and winnowed. Roots, leaves, flowers, seeds and oil constitute the economic parts. The average yield is 500-600kg/ha (Thakur, 1990).

Properties and activity: The beancoat yielded lupeol and 30-norlupan-3 -ol-20-one. Roots, stems and leaves contain several amino acids. Flowers gave apigenin, chlorogenin, rutin, coumarin and hyperoside. Castor oil is constituted by several fatty acids (Husain et al, 1992). Seed coat contained 1. 50-1. 62% lipids and higher amounts of phosphatides and non-saponifiable matter than seed kernel. Fresh leaves protected against liver injury induced by carbon tetra chloride in rats while cold aqueous extract provided partial protection (Rastogi et al, 1991). Root and stem is antiprotozoal and anticancerous. Root, stem and seed are diuretic. The roots are sweet, acrid, astringent, thermogenic, carminative, purgative, galactagogue, sudorific, expectorant and depurative. Leaves are diuretic, anthelmintic and galactagogue. Seeds are acrid, thermogenic, digestive, cathartic and aphrodisiac. Oil is bitter, acrid, sweet, antipyretic, thermogenic and viscous (Warrier et al, 1996). Castor oil forms a clean, light- coloured soap, which dries and hardens well and is free from smell. The oil varies much in activity. The East Indian is the more active, but the Italian has the least taste. Castor oil is an excellent solvent of pure alkaloids. The oil furnishes sebacic acid and caprylic acid. It is the most valuable laxative in medicines. It acts in about 5 hours, affecting the entire length of the bowel, but not increasing the flow of bile, except in very large doses. The mode of its action is unknown. The oil will purge when rubbed into the skin (Grieve and Leyel, 1992).... castor

Trigonella foenum-graecum

Fabaceae

San: Methika, Methi, Kalanusari;

Hin: Meti, Mutti; Ben, Mar: Methi;

Mal: Uluva;

Importance: Fenugreek or Greek Hayes is cultivated as a leafy vegetable, condiment and as medicinal plant. The leaves are refrigerant and aperient and are given internally for vitiated conditions of pitta. A poultice of the leaves is applied for swellings and burns. Seeds are used for fever, vomiting, anorexia, cough, bronchitis and colonitis. In the famous Malayalam treatises like ‘Padhyam’ ‘Kairali’ and ‘Arunodhayam’, uluva is recommended for use as kalanusari in Dhanvantaram formulations of ‘Astaghradayam’. An infusion of the seeds is a good cool drink for small pox patients. Powdered seeds find application in veterinary medicine. An aqueous extract of the seeds possesses antibacterial property (Kumar et al, 1997; Warrier et al, 1995).

Distribution: Fenugreek is a native of South Eastern Europe and West Asia. In India fenugreek is grown in about 0.30 lakh ha producing annually about 30,000 tonnes of seeds. The major states growing fenugreek are Rajasthan, Madhya Pradesh, Gujarat, Uttar Pradesh, Maharashtra, Punjab and Karnataka. It is grown wild in Kashmir and Punjab.

Botany: Trigonella foenum-graecum Linn. belongs to family, Fabaceae. It is an annual herb, 30-60cm in height, leaves are light green, pinnately trifoliate, leaflets toothed, flowers are white or yellowish white, papilionaceous and axillary. Fruits are legumes, 5-7.5cm long, narrow, curved, tapering with a slender point and containing 10-20 deeply furrowed seeds per pod. There are two species of the genus Trigonella which are of economic importance viz. T. foenum graecum, the common methi and T. corniculata, the Kasuri methi. These two differ in their growth habit and yield. The latter one is a slow growing type and remains in rosette condition during most of the vegetative growth period (Kumar et al, 1997; Warrier et al, 1995).

Agrotechnology: Fenugreek has a wide adaptability and is successfully cultivated both in the tropics as well as temperate regions. It is tolerant to frost and freezing weather. It does well in places receiving moderate or low rainfall areas but not in heavy rainfall area. It can be grown on a wide variety of soils but clayey loam is relatively better. The optimum soil pH should be 6-7 for its better growth and development. Some of the improved cultivars available for cultivation are CO1 (TNAU), Rajendra Kanti (RAU), RMt-1(RAU) and Lam Selection-1 (APAU). Land is prepared by ploughing thrice and beds of uniform size are prepared. Broadcasting the seed on the bed and raking the surface to cover the seeds is normally followed. But to facilitate intercultural operations, line sowing is also advocated in rows at 20-25cm apart. Sowing in the plains is generally in September-November while in the hills it is from March. The seed rate is 20-25kg/ha and the seeds germinate within 6-8 days. Besides 15t of FYM, a fertiliser dose of 25:25:50kg NPK/ha is recommended. Entire P,K and half N are to be applied basally and the remaining half N 30 days after sowing. First irrigation is to be given immediately after sowing and subsequent irrigations at 7-10 days interval. Hoeing and weeding are to be done during the early stages of plant growth and thinning at 25-30 days to have a spacing of 10-15cm between plants and to retain 1-2 plants per hill. Root rot (caused by Rhizoctonia solani) is a serious disease and can be controlled by drenching carbendazim 0.05% first at the onset of the disease and another after one monthof first application. In about 25-30 days, young shoots are nipped off 5cm above ground level and subsequent cuttings of leaves may be taken after 15 days. It is advisable to take 1-2 cuttings before the crop is allowed for flowering and fruiting when pods are dried, the plants are pulled out, dried in the sun and seeds are threshed by beating with stick or by rubbing with hands. Seeds are winnowed, cleaned and dried in the sun. They may be stored in gunny bags lined with paper. An yield of 1200-1500kg of seeds and about 800-1000kg of leaves may be obtained per hectare in crops grown for both the purposes (Kumar et al, 1997).

Properties and activity: Seeds contain sapogenins-diosgenin, its 25-epimer(yamogenin), tigogenin, gitogenin, yuccagenin, 25-2-spirosta-3-5-diene and its -epimer. Seeds also contain a C27-steroidal sapogenin-peptide ester-fenugreekine. Seeds, in addition, contain 4-hydroxyleucine and saponins-fenugrins A-E:two furostanol glycoxides-trigonelloxide C and (255)-22-O-methyl-52-firostan-3 ,22,26,triol-3-O- -rhamnopyrans syl(1-2) C- -D-glucopyranosyl (1-3)- -D- glucopyranoxide-26-O- -D-glucopyranoxide.

Other chemical constituents are sterols- -sitosterol and cholesterol, flavone C- glycosides-vitexin, iso-vitexin, vitexin-2”-O-P-coumarate and vicenin-2. Flavonoids- quercetin and luteolin, flavonoid glycoside-vicenin-I. Invitro seedling callus culture gave flavonoids-luteolin and vitexin-1-glycoside. An essential oil is also reported from seeds. Leaves gave saponins-gracecunins A-G, flavonoids- kaempferol and quercetin; sterols- - sitosterol, sapogenins-diosgenin, gitogenin coumarin-scopoletin is also reported from the plant.

Seeds are bitter, mucilaginous, aromatic, carminative, tonic, diuretic, thermogenic, galactagogue, astringent, emollient, amophrodisiac, antirheumatic, CNS depressant and antiimplantation. Fenugreekine is hypoglycaemic, diuretic, hypotensive, cardiotonic, antiphlogistic. It showed 80% inhibition of vaccina virus.... fenugreek
