BLACK GRAM (Vigna mungo) - A hypolipidemic pulse

M. Indira and P. A. Kurup

 

Black gram is a pulse commonly used in Indian cuisine. Systematic studies on the effect of lipid lowering action by common pulses revealed that black gram possesses significant hypolipidemic action. Detailed experimental studies in animals have shown that a polysaccharide and a protein fraction contribute to the hypolipidemic action. Glycosaminoglycan metabolism is altered by inclusion of these fractions in the diet. Neutral detergent fiber isolated from black gram possesses significant hypolipidemic, hypoglycemic and anticolon-cancer activity.

 

 

 
Grow sugarcane, cotton and pigeonpea in nursery

 A. D. Karve

 

A delay in the date of planting crops generally results in reduced yield. But if the growth of the plants is started at the appropriate time in plastic bags, and the seedlings are transplanted into the field when the field is ready to receive them, yield loss due to delayed planting is avoided. This is a typical low-cost and eco-friendly input, which gives high yield without using additional agrochemicals.

 

 

Insecticidal potential of wild bean seed protein, arcelin

S. Janarthanan and P. Suresh

 

During the co-evolutionary process, plants have yielded many organic compounds. These compounds have been found to overcome the predatory potential of herbivores. The use of such compounds in Integrated Pest Management (IPM) is on the rise. Wild pulses such as Vigna spp., Cajanus spp. and Lablab spp. found in Palney Hills, Western Ghats, Tamil Nadu were evaluated and reported to possess several such insect-antimetabolic compounds, of which arcelins play a major role in plant defense mechanism against their insect pests, mainly to bruchids (Osborn et al, 1988; Dillen et al, 1997; Goossens et al, 1999; Janarthanan et al, 2002). Arcelin has been identified and isolated for the first time from seeds of the wild specimens of Lablab purpureus (Linn.) Sweet in India and its antibiosis against the stored product insect pest, Callosobruchus maculatus (F.) is reported here.

 

 

 

BOTTLE GOURD (Lagenaria siceraria)
A vegetable for good health

A.S. Habibur Rahman

 

The gourd is used as curative plant for mental health disorders. Among cucurbits, the bottle gourd, Lagenaria siceraria (Mol) Standl. is the only plant which contains highest choline level along with required metabolites/metabolic precursors for brain function. The purpose of this paper is to explore scientific creditability of narration of gourd in the scriptures of the world and traditional usage. The biological activities of important members of family Cucurbitaceae on human body have also been presented. It is emphasized that these plants are having high therapeutic values and must be consumed as daily nutrition. From the point of pharmacological function the seeds are advised for consumption, as they have more nutrition and omega fatty acids.

 

 

Flavour

 

Lemon scented plants

 

K. P. Svoboda and R. I. Greenaway at UK have reported that a large number of plant species has wonderful citrus scent, or just a pleasant hint lemon fragrance. Leaves, flowers, needles, cones or wood can be the source of original material. Review published by them gives a summary of both established and new species on the world market, with detailed description of five more unusual representatives of this group, including the chemicals responsible for the lemon scent. Out of about 54 species listed in the paper following species are found in India also: Pereskia aculeata Mill., Cucumis melo Linn., Morina longifolia Wall., Pelargonium capitatum Ait., Cymbopogon citratus Staff., Cymbopogon nardus (Linn.) Rendle, Melissa officinalis Linn., Mentha piperata var. citrata, Nepeta cataria Linn., Callistemon citrinus, Eucalyptus citriodora Hook, Oenothera odorata Jacq., Passiflora foetida Linn., Aloysia triphylla (L Herit.)Britton [Svoboda & Greenaway, Intern J Aromatherapy, 2003, 13(1), 23-32].

Oil/Fats

 

 

 

Palm oil alleviates tumour promotion

 

The studies suggest that palm oil may be an effective anti-tumor promoter, and delay cutaneous tumor induction and development. The results also suggest that palm oil is an effective suppresser of malignant tumor growth in murine skin and that it acts by inhibiting cutaneous oxidative stress (Kausar et al, Cancer Letters, 2003, 192, 151160).

 

 

 

Projects/Schemes

 

Aloe vera cream for burn applications

 

The Natural Products Development Group of the Agro & Food Technology Division of the Industrial Technology Institute, Sri Lanka has, after an years research programme, successfully developed the technology for an Aloe vera Linn. cream for burn applications. Clinical trials carried out at the National Hospital, Colombo with this cream, have indicated that it has better healing properties than the silver sulphadiazine cream which is used at present on patients with burns. This technology is available for sale to potential entrepreneurs. Before purchase of technology, the ITI will provide sample batches for test market trials, advice on equipment and information on suppliers. Other products have also been developed at the ITI, using Aloe vera. These include, moisturisers, cold cream, shampoo, hand cream and body gel. A sunscreen cream having a sun protection factor equivalent to imported samples using Aloe vera, carrot and Centella extracts has been yet another product. Trials on the cultivation of this plant are now being carried out on a large scale.
