Abstract

The chemical constituents of an essential oil obtained from the leaves and stems of the plant Zingiber officinale Roscoe of a red type, have been studied using gas -liquid chromatography. The oil contains linalyl acetate (37.9%) as the major component. Some other abundant constituents were also identified which are geranial (9.35%), neryl acetate (6.23%), terpenyl acetate (5.66%), and one which is still unidentified (6.78%). The high content of linalyl acetate showed that the oil, which is comparable to that of bergamot oil, be a valuable commodity and affirms that another type of essential oil has been recognized.

Abstract

In search for the aroma industrial utilization of indonesia essential oils of non-exported commodities,yhe main chemical constituents of essential oils originated from the plant species of some cinnamomum,e.g. c.javanicum, c.camphora and c sintok,also foeniculum vulgare,hyptis suaveolens and ocimum canum,which are all grown likely in indonesia,were surveyed by literature.Based on criterion that the amount of each constituents present inthe oil must exceed  10%, enantiomerically pure and harmless to man.it was found found that the cinnamomum species be likely the sources of safrole,whereas only foeniculum vulgare be likrly the source of fenchone.

Abstract

A research on the effect of duration and methods of extraction to the quality of gambier has been conducted. Leaves of gambier from Uncaria gambir Roxb were extracted by steaming and boiling for 5, 10 and 15 minutes, then pressed with hydraulic press in 18.000 kg/cm^2 pressure and dried for 3-4 days. All of the gambier product from these extraction treatment have the same quality but the best quality of gambier could be found by steaming for 5 minutes
