Abstract: Valeriana jatamansi Jones (Valeriana wallichii DC), family Valerianacae is a perennial plant with wide green leaves. Local names of the plant are Tagar (Hindi), Tagara (Sanskrit) and Indian Valerian (English). The plant is native to temperate zones of Himalayas and is found abundantly from Kashmir to Bhutan at an altitude of 1300-3000m, in the Khasia Hills (India) and in Afghanistan and Pakistan . Essential oil for commercial use is extracted from the roots and rhizomes of this plant which is used as mild sedative. The derived medicine is used for nervous debility and failing reflexes. It is also used in the treatment of hysteria, hypochondriasis, mental illness and depression etc. Valepotriate and essential oil deried from this plant are in high demand in India and European countries. It is multiplied mostly by rhizomes and is transplanted in field during March to April and October with a spacing of 30×30 cm. It bears flowers in February and seeds are formed in March to April. Vaieriana jatamansi can also be multiplied by seeds. Drainage and shade are important for growth and development of the plant. The roots and rhizomes are parts of prime importance which are reported to yield essential oil (0.3-0.5%) and valepotriate (1.8-6.0%). It can yield up to 0.8-1.0 MT/ha roots of economic importance. Chemical analysis revealed the presence of two types of chemotypes. Some have Patchouli alcohol as characteristic compound while others have maaliol as the main constituent of essential oil. The chemotypes having Patchouli alcohol between 35-40% are in more demand in the trade. Institute of Himalayan Bioresource Technology is presently engaged in developing agro techniques for commercial cultivation of Valeriana jatamansi so that high quality morphotypes can be produced and di stributed to farmers to enable them to fetch good quality essential oil as well as valepotriate.
