    Traditional medicinal knowledge has gained much attention recently due to rejuvenation of faith in traditional system of medicines. The Indian Himalaya is a source of plant based indigenous medicinal knowledge based on local plant diversity. Surveys were conducted in Rudraprayag district of Uttarakhand, India to collect indigenous information on primary health care. 29 formulations using 159 plant species were recorded treating 119 ailments in 13 broad therapeutic classes. Results have been compared with traditional knowledge from other parts of India

    Antioxidant Properties of Alpine Plant

    Get PDF
    Alpines are the exceptional regions of the world’s biomes. They have unique climatic and topographic conditions; they are the habitat of some of the highly specialized flora and fauna. The harsh environmental conditions and extreme fluctuations in them on a seasonal and diurnal basis created extremely stressful situations for the alpine plants. Such stress causes damage to biochemical structures and compounds of the plant cells leads to the production of free radicals, i.e. reactive oxygen species (ROS), which can further damage the plant cells or tissues. Alpine plants protect themselves from those ROS efficiently by their highly competent enzymatic and non-enzymatic antioxidant system. In general, this protection increases in alpine plants with altitudes; however, some exceptions are also reported. Antioxidant compounds viz. ascorbic acid, tocopherol, glutathione, carotenoids found in alpine flora in higher concentrations as compared to low land plants. Phenolic compounds protected the alpine plants from UV induced ROS by screening the UV radiations and blocking their entries in the cell’s mesophyll. This higher antioxidant potential of the alpine plants is highly beneficial for the human being as most alpine plants are the sources of some life-saving drugs

    Ecological features and traditional knowledge of Roscoea alpina Royle a medicinal plant in Himalaya

    Roscoea alpina Royle (Zingiberaceae) commonly known as Kakoli is a perennial medicinal herb endemic to the Himalayas. It is used in vitality strengthening Ayurveda groups i.e., Astavarga and Jeevaniyagana and in preparation of Ayurvedic formulations e.g., Chyavanprasha and Divya Pidantak Tail. Considering its medicinal uses, high demand and overexploitation, natural habitats were surveyed in subalpine and alpine regions of Garhwal Himalayas for population estimation and to identify elite germplasm. R. alpina frequency was recorded more than 60 % in Tungnath, Dayara, Valley of Flowers and Kedarnath populations. However, plant density and area occupied were low compared to other species of subalpine and alpine region. For threat category assessment, IUCN Red List Categories and criteria were used and conservation status was assigned, based on site to site and for entire Garhwal region of the Western Himalaya. R. alpina, based on extent of occurrence was categorized as Vulnerable and based on number of mature individuals as Endangered for the Garhwal Himalaya. Further, habitat destruction and degradation were the major threats for population reduction in the wild. Morphological variation revealed plants from Tungnath and Kedarnath may be used for future propagation and domestication efforts

    A look at S&T Awareness - Enhancements in India

    No full text
    Basing mainly on author's direct involvement in some science communication efforts in India, and other reports, this contribution depicts and analyses the present science communication/ popularization scenario in India. It tries to dispel a myth that rural people don't require or don’t crave for S&T information. It discusses need for science and technology communication, sustaining curiosity and creating role models. Citing cases of some natural, 'unnatural' and organized events, it recounts how S&T popularization efforts have fared during the past decade and a half. It's made possible using print, AV and interactive media which, at times, require lot of financial inputs. However, this contribution shows that a number of natural and other phenomena can be used to convince people about power of S&T and in molding their attitude. The cases cited may be from India, but, with a little variation, are true for most of the developing and under- developed societies

    Variation in morphological, biochemical and antioxidant properties of Lilium polyphyllum

    No full text
    237-245Lilium polyphyllum D.Don ex Royle belonging to family Liliaceae is a medicinal plant distributed in temperate to high altitude regions of Himalaya. Its bulbs have been used for anti-aging and vitality properties in >30 formulations of Ayurveda.Therefore, the knowledge on various traits of the plant is necessary so that quality of the finished products could be maintained. Present study investigates, morphological, biochemical and antioxidant properties in different populations of L. polyphyllum. A significant variation was recorded in different morphological parameters (Plant height, leaf number, leaf length, leaf width, bulb diameter, bulb fresh weight). Variation was also recorded for total soluble protein (7.81-11.35 mg/g), soluble sugar (96.14-116.14 mg/g), starch (116.37-122.43 mg/g) and total free amino acid (18.22-26.00 mg/g). Antioxidant properties in the bulb were determined and ABTS activity was 4.22 mM /100 g, DPPH activity recorded 0.85 mM/100 g and FRAP activity was 1.50 mM/100 g dw ascorbic acid equivalent, respectively. The diversity in wild populations of the species may serve as a baseline data for future breeding, domestication and conservation program

    Overcoming root dormancy and identifying the storage behaviour of Lilium polyphyllum seeds

    Lilium polyphyllum is a critically endangered medicinal herb of Himalaya. Seeds have epicotyl morphophysiological dormancy, and in the field a minimum of 34 weeks is required for root emergence. To date, treatments to decrease the time for root protrusion and seed storage behaviour have not been determined. We evaluated the effects of plant growth regulators and nitrogenous compounds and seed scarification on root emergence and determined the storage behaviour of seeds. Root emergence at 20°C was significantly increased by 100 ppm IBA, KNO3 and thiourea and by application of NaOCl solution for 30 min. Mean germination time was decreased significantly by 50 ppm GA3 (28 days) compared to 100 ppm GA3 (36 days). After 12 months of dry storage, viability of seeds (TTC method) at room temperature (10-35°C), 0-4°C and -20±1°C was 95%, 100% and 100%, respectively; thus, seeds have orthodox storage behaviour. Our recommendation for seedling production is to store seeds at room temperature until they can be sown under warm wet conditions. Roots emerge after about 8 weeks, and then seeds should be given a 2-week cold moist treatment to break shoot dormancy. After 2 weeks of cold, transfer seeds to warm (20°C) spring temperatures to promote growth.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
