The gum resin of S. benzoin is a very important commodity in the world of industrialization and really needs the attention of the frankincense farmers. This is based on the many benefits of the plants which are only limited to livelihoods. The purpose of the research are to know the results of increasing the stability of the gum styrax benzoin with the addition of cosolvents. The identification of the components of secondary metabolites using phytochemical screening. The methodology of the research is maceration the gum styrax benzoin ash with Etanol solvent until all samples are immersed and carried out in a glass bottle for three days. The research was continued with identification of the components of secondary metabolites using phytochemical screening. The findings of the research is analysis using phytochemical screening shows the secondary metabolites styrax benzoin such as alkaloids, flavonoid, tannin, saponin, and terpenoid. The limitations of the research is focuses on 3 variations in the Cosolvent of propylene glycol, polyethylene glycol and triethanolamine. The reserch have value specifically the gum styrax benzoin is used as the solubility of several pharmaceutical compunds.

This research to decide the consequences of expanding the steadiness of the concentrate and part of incense with the expansion of glycerol and tween 80 by contrasting the reference tests of frankincense separates available. The technique utilized in this examination depends on the expansion of glycerol and tween 80, just as directing boundaries of consistency, organoleptic, pH and investigation of substance content of concentrates and parts with GC-MS instruments. The outcomes got in this investigation demonstrate the actual properties of the concentrate and part of the incense sap as a thick fluid, earthy red and has an unmistakable fragrant smell. The consistency got from the thickness test was 277.68 Cp. In the meantime, the thickness estimation consequences of the reference test acquired a consistency worth of 326.54 cP. What's more, has a pH scope of 4.0-5.5. The fundamental synthetic parts of the extraction results and the isoprophyl part of styrax benzoin and the reference part of the reference styrax benzoin remove dependent on the consequences of the investigation discovered 6 mixtures that share practically speaking, in particular Benzoic corrosive, Vanillin, trans-Cinnamic corrosive, (Z) - Cinnamyl benzoate, 2-Propenoic corrosive , 3-phenyl-, phenylmethyl ester, (E) - and Cinnamyl cinnamate.
