Major chemical constituents responsible for physicochemical and therapeutic action of the herb are :- Anisalclehyde Sesquiterpene alcohols d-a-thujone x-pinene Phenolic compounds Gum – arabinose Xylose Galactose Enzyme – diastatic Resins Volatile oil of this drug contains anisalclehyde, sesquiterpene alcohols, d-a-thujone, x-pinene and phenolic compounds and in small proportion b-cymene, d-limonene, terpinolene, a-piviene, a-thujone, a-phellandrene, a-terpineol, bornyl acetate and methyl chavicol. Gum is a composition of arabinose with small amounts of xylose and galactose and it also contains oxidizing and diastatic enzymes. The highly brittle resin is soluble in various organic solvents and softens between 65-700C and melts between 70-750C. Indian olibanum contains P-boswellic acid in resin portion. Volatile oil contains /p>

To maintain physicochemical properties and medicinal values of the herb it is recommended to maintain following storage conditions:- Air tight containers Protection from light
