CSIR-IHBT Annual Report 2010-11Utilization of locally available plant raw materials for fetching high pricesA pilot scale process was standardized for extraction of β-aescin (1.2% w/w) from Aesculus indicaseeds. A total of 400 g aescin was produced from 7 batches.In another study, oil was also extracted from rose and apple seeds. Apple seed oil contained linoleic(50.77%), oleic (38.78%), palmitic (7.85%) and stearic (1.93%) acids. In rose seed oil, linoleicacid (45.38-54.58%), linolenic acid (13.67-24.75%), oleic acid (11.97-21.08%), palmitic acid (6.54-12.97%), stearic acid (3.37-5.79%) and arachidic acid (0.85-1.99%) were the major fatty acids.In characterization and value addition of major chemical constituents of C. deodara, the yields ofwood essential oils and extracts from the hydro distillation and percolation of wood chips were0.98% and 14.50%, respectively, on dry weight basis. A total of 34 and 26 constituents were identifiedin the oil and woodchip extracts, respectively by GC-MS. Himachalene (23.53%-68.52%) andatlantone (15.02%-61.60%) were the major constituents. The fragrance was improved to sweet,fruity and slight woody note.Training on distillation of essential oils from local aromatic resourcesTraining Date No. ofparticipantsZoneDistillation of essential oils from localaromatic resources16.7.2010 45 Village Ballah,KangraExtraction of aromatic oils 11-12.10.2010 30 Village Nagwain, MandiPOME AND STONE FRUITSVirus tested planting material production technology for apple, plum and cherryVirus free rootstocks and budwood of apple, plum and cherry were developed for distribution tothe farmers for enhanced production of quality fruits. Apple plants were distributed to cover an areaof about 90 ha.APPLE (Malus domestica)SurveyIn June, 2010, farmers’ field and nurseries that supply apple rootstock and budwood were surveyedfor virus incidence in Shimla district. Multiple virus infection due to ACLSV, APMV, ASPV andASGV, and Apple scar skin viroid infections were found to be widespread in the surveyed orchards.However, 145 out of 250 trees of cvs Starkrimson, Vance Delicious, Oregon Spur, Red Chief andSilver Spur were free from virus and viroid.Additional area covered with virus free plantsVirus free cultures of apple were provided to M/s Rajat Biotech, Bilaspur, Neva Plantations, Kangraand Monal Biotech, Una, H.P. A total number of 90,000 nursery plants produced by these unitswere supplied to growers to cover 81ha area.82
