Annual Report - IHBT

CSIR-IHBT Annual Report 2010-11The essential oil composition of leaves and stems was determined for the first time. trans-Caryophyllene, humulene, nerolidol and spathulenol were identified as the major constituents.A commercial plant of 300 kg/day capacity to process dry leaves was installed, commissioned andhanded over to M/s Jallan Trinitea Processing Pvt. Ltd., Gurgaon. A total of 89 batches of 50 kgeach were processed. Total steviol glycosides of 402.52 kg were produced from 4450 kg of dryleaves with an average yield of 9% (w/w).SAFFRON (Crocus sativus)Saffron is an expensive spice used for flavoring and coloring foods. Two marker compounds,Crocin-1 and 2 were isolated from aqueous extract of dried stigma and analysed by HPLC.The growth performance of in vitro cormlets and in vivo corms produced at IHBT was evaluatedat saffron research centre, Sher-e-Kashmir University of Agriculture Sciences and Technology,Kashmir (SKUAST-K) (Fig. 49). The in vivo produced cormlets (5-7g) performed better thanthe in vitro cormlets (Table 18).Table 18 Performance evaluation of in vitro cormlets and in vivo cormsWeight (g) Sprouting (%) Mean daysfor leafemergenceFold increasein corm numberMean days forfloweringMean lengthof stigma(cm)
