Patals of gardenia were extracted by using maceration technique with hexane and
petroleum ether. The result showed that the optimum ratio of hexane extraction was 70 g
flower/l the percentage yields of hexane concrete and absolute were 0.0813 and 0.0600%,
respectively (Figure 3a). The saturated point of Petroleum ether to extract the scent from
gardenia was 60 g flower/l and percentage yield of petroleum ether concrete and absolute
were were 0.0562 and 0.0446%, respectively (Figure 3b). The characteristic of gardenia
absolute from hexane extraction was waxy substance, reddish brown color and sweet odor.
Petroleum ether extraction gave pink waxy substance with sweet and strong gardenia odor.
The chemical constituents of gardenia absolute from hexane and petroleum ether extraction
were ten and three major compounds. (Figure 4 and Table1) The main constituents of absolute
from hexane and petroleum ether were methyl benzoate and (Z)-3-hexenyl tiglate
