    Rosin Gum 

    Plants secrete resin and rosins for their protective benefits.And the resin is composed mainly of terpenes and derivatives.The individual components of resin can be separated by fractional distillation.Rosins on the other hand are less volatile and consist, inter alia,of diterpenes.

    Solidified resin from which the volatile terpene components have been removed by distillation is know as rosin.Typical rosin is transparent or translucent mass,with a vitreous fracture and a faintly yellow and brown colour, non-odorous or having only a slight turpentine odor and taste.Rosin is insoluble in water,mostly soluble in alcohol,essential oils,ether and hot fatty oils,and softens and melts under the influence of heat,and burns with a bright but smoky flame.

    Plant resins are valued for the production of varnishes,adhesives,they are also prized as raw materials for the synthesis of other organic compounds and provide constituents of incense and perfume.While the softer odoriferous oleo-resins and gum resins containing essential oils are more used for therapeutic purposes and incense.
