1.The result found ethanol is the highest one as 65.9% that extracted contents about solvent, average percent is 68.4 and extracted solvent of mastic is suitable for ethanol.
2. The physical property of frankincense resin, fixedness matter accounted for 78% and viscosity was 16cP
3. Moisture absorption rate of frankincense resin showed 0.48.
It was fine by standards.
4. Ingredient of mastic is mainly composed with pinene of monoterpene, camphene, myrcene and limonene. The rest is composed with copaene of sesquiterpene, humulene and cadinene.
5. Antifungal vitality did nothing to act about mold and Altenaria SP . But, Rhizoctonia Solani and Fasarium oxysporum. took antifungal effect.
6. Anti-fungal properties were showed frankincense essential oil and the effect were showed at twice dilution, too.
7. In termiticidal efficacy test, it showed 82.5% that mortality of three weeks later. We decided that this result showed termiticidal efficacy.
8. In antisepsis activity test, three virus (white and brown rotting fungi) showed they have antisepsis effect. So we found it will be use as natural preservative.
9. Tensile shear strength of O-kong bond's addition in frankincense resin increased a little on O-kong bond's addition rate.
It showed 0.72(N/㎟) averagely from 0.5 to 1 at rate.
This figure was above regulation on Korean Standards of needleleaf and broadleaf tree.
10. Formaldehyde emission of O-kong bond's addition in frankincense resin was under the range of legal regulation as 0.037 ~ 0.049 (㎖).
11. Frankincense resin is expected to use lumber glue and food packing, because it have anti-fungal properties and termiticidal efficacy
