Effect of mixed-cropping and water-stress on macro-nutrients and biochemical constituents of rhizomatous medicinal plants in Central Himalaya, India

Plants in the alpine zone mainly depend on the reserved food materials stored in their rhizomes for the next growing season.We investigated the effect of mixed cropping(Phaseolus vulgaris L.var.Pinto) with four rhizomatous medicinal plants,i.e.,Angelica glauca,Arnebia benthamii,Rheum emodi and Pleurospermum angelicoides as well as three levels of water stress treatment under two conditions(shade net and open field) on macronutrients(NPK) and biochemicals(carbohydrates and protein).The experiment was conducted by completely randomized design(CDR).The data were analyzed with ANOVA as well as CDR.The experimental results show that in all the species shade conditions with sever water stress(SSWS) increased the level of macronutrients(NPK).However,(N) concentration was highest under shade with mixed cropping(SMIX).Under SMIX,carbohydrate content was highest than open field control conditions(CONT).This investigation results demonstrate that mixed cropping of medicinal plants with Phaseolus vulgaris could be a good livelihood option in the mountainous regions of Indian Central Himalaya.And the water-stress conditions along with mixed cropping could improve the biochemical constituents in the rhizome of these species.     

The effect of ultraviolet radiation on the accumulation of medicinal compounds in plants

A review is given of how the production by plants of compounds useful as medicines or raw materials for manufacture of medicines is influenced by ultraviolet radiation, particularly by UV-B radiation (280–315 nm wavelength). The compounds considered in this review are flavonoids and other phenolics, alkaloids (especially indole terpenoid and purine alkaloids), essential oils and other terpenoids, cannabinoids, glucosinolates and isothiocyanates, and compounds having human hormone activity. A short account is also given of ultraviolet signalling in plants. The review concludes with a discussion of the possible evolutionary mechanisms that have led to the evolution of UV-B regulation of secondary metabolite accumulation.

A study was conducted to examine the distribution pattern of four rhizomatous medicinal and aromatic plant species (MAPs) viz., Angelica glauca, Pleurospermum angelicoides, Rheum emodi and Arne- bia benthamii in different forest stands in Central Himalaya. Results show that A. glauca and P. angelicoides had a higher (50%) frequency at Chipkoan, Garpak and Phagati forest, R. emodi had a higher (60%) frequency at Rishikund, Suki and Himtoli, and A. benthamii had a higher (70%) frequency at Suki and Khambdhar The densities of A. glauca (0.6 plants·m -2 ) and P. angelicoides (0.5 plants·m -2 ) were higher at Chipkoan and Garpak sites than at other micro-sites, while densities of R. emodi (0.8 plants·m -2 ) and A. benthamii (1.0 plants·m -2 ) were higher at Suki and Khambdhar sites. A. glauca had highest total basal covers (TBC) (1.2 cm 2 ·m -2 ) at Chipkoan, P. angelicoides had highest TBC (0.92 cm 2 ·m -2) at Lati kharak site, A. benthamii had the highest TBC (6.48 cm 2 ·m -2 ) atKhambdhar, and R. emodi had highest TBC (4.53 cm 2 ·m -2 ) at Rishikund. For the four studied species, A. glauca showed a contagious distribution, P. angelicoides and R. emodi showed the random and A. benthamii showed the regular type of distribution.

An ethnobotanical survey of medicinal plants used by ethnic people in West and South district of Tripura,India

An ethno-medicinal investigation was conducted to highlights the traditional knowledge of medicinal plants being used by the tribe in West and South district of Tripura. This paper provides information about the different uses of plants used in their primary health care system. Tripura is a small north-eastern state of India and also a part of both Himalayan and Indo-Burma biodiversity region. It is a goldmine of medicinal plants and use of different plants in tribal traditional heath care systems has long history. Nineteen different tribes in Tripura, depend on natural resources at a great extent. This paper documented 113 medicinal plant species from 56 families along with their botanical name, local name, family name, habit, medicinal parts used, and traditional usage of application. The dominant families are Euphorbiaceae (7 species), Apocynaceae (6 species), Fabaceae and Rubiaceae (5 species each), Caesalpiniaceae, Asteraceae, Liliaceae and Verbenaceae (4 species each), Combretaceae, Labiatae, Malvaceae, Rutaceae and Zingiberaceae (3 species each). Tribes of Tripura have rich traditional knowledge on plant based medicine. Different parts of the plants in crude form/plant extracts/decoctions/infusion or pastes are employed in diverse veterinary and human diseases by the tribe’s of Tripura in daily life.

Plant folk medicines for gastrointestinal disorders among the main tribes of Sonora, Mexico

This paper describes the herbal remedies used by ethnic groups from Sonora, Mexico, for treatment of gastrointestinal diseases. Twelve types of these illnesses are cured using 85 different species which belong to 38 families. Thirty nine spp. are used to treat diarrhea, 28 for stomach-ache, 12 for constipation, 9 for intestinal parasites, 6 for indigestion, 3 for stomach or intestinal cancer, 3 for stomach inflammation and only 1 to treat gastrointestinal sicknesses, ulcers, gastritis, colitis and colic. Regarding the use of species of plant per ethnic group the following was observed: Mayo 47; Seri, 27; Yaqui, 13; Guarijio, 12, Pima, 5 and Papago, 3. The plants are used by two or more tribes, for the same or different illness but always related to the gastrointestinal system.

Transitioning from wild collection to forest cultivation of indigenous medicinal forest plants in eastern North America is constrained by lack of profitability

The forest flora of eastern North America includes many herbaceous plant species traded in domestic and international medicinal markets. Conservation concerns surrounding wild-collection exist and transitioning to cultivation in agroforestry systems has potential economic and ecological benefits. Costs and revenues associated with adopting forest cultivation were modeled for eight North American medicinal forest plants. Sensitivity analysis examined profit potential in relation to (1) discount rates; (2) propagation methods; (3) prices; (4) growing period; (5) production costs; and (6) yields. Results indicate that intensive husbandry of six of eight species would be unprofitable at recent (1990–2005) price levels. Exceptions are American ginseng (Panax quinquefolius L.), and under certain circumstances (e.g., maximum historic prices, low production costs) goldenseal (Hydrastis canadensis L.). Direct marketing to consumers and retailers might improve grower profits, but is undermined by the availability of cheaper, wild-collected product. We suggest that the North American medicinal plant industry could play a key role in facilitating any transition from wild to cultivated product, perhaps through development of a certification and labeling program that brands “forest cultivated” products. This could generate price premiums, to be passed along to growers, but must be accompanied by aggressive consumer education. A “forest cultivated” certification and labeling program has potential to benefit industry and consumers if assurances regarding product identity and quality are a central feature. Plant species that are not viable candidates for commercial cultivation due to limited consumer demand (i.e., species with “shallow,” erratic markets) are best addressed through proactive government and industry initiatives involving targeted harvester education programs.
