Annual Report - IHBT

CSIR-IHBT Annual Report 2010-11DEODAR (Cedrus deodara)Deodar is native to the Himalayan region. The plant is the main source of cedar wood oil havingvaried industrial applications. Five sesquiterpenes, α-himachalene, β-himachalene, γ-himachalene,atlantolone, (E)-α-atlantone were isolated and characterized from n-hexane and chloroformfractions (Fig. 35).Fig. 35 Chemical structures of sesquiterpenes isolated from C. deodaraCHINESE ALBIZIA (Albizia chinensis)It is a native of mixed deciduous forests of humid tropical and sub-tropical monsoon climates andreported to have antioxidant, antiseptic, anti-dysenteric, anti-tubercular, anti-tumor, spermicidal,molluscicidal and insecticidal properties. Thirteen marker compounds in the categories offlavonoids and phenolics were isolated and characterized (Fig. 36).Fig. 36 Chemical structures of marker compounds isolated from A. chinensisSCENTED ROSE (Rosa spp.)Rosa damascenaA total of 7305.50 kg fresh rose flowers were distilled at pilot scale to produce rose oil and water. About2220 ml of rose oil was recovered from 5797.9 kg of fresh rose flowers with an average oil yield of0.038% (v/w). About 1500 l of rose water was produced from 1500 kg rose flowers (Table 10).39
