Main Component

The study to improve the quality of Indonesia betel leaves oil is done by treatment of citric acid and sodium carbonate. The treatment showed that the iron content and acid value were reduced optimally in the addition of 5% (w/w) citric acid (12 hours, 50oC) and 5% (w/w) sodium carbonate (9 hours, 50oC) yielded 0.45 mg/L of iron content and 1.00 mg/g of acid value, respectively. The main component of Indonesia betel leaves oil are 4-allyl phenylacetate. The descriptive sensory analysis showed that there were differences between betel leaves oil from Bogor compared with Boyolali and Makassar. There is a significant difference that the content of betel leaves oil from Bogor contains an isoeugenol compound of 20.71% while, Boyolali and Makassar contain eugenol of 17.02 and 19.21%, respectively. The study of the insect repellency indicated that Indonesia betel leaves oil potentially used as mosquito of Aedes aegypti repellent.

The motility of fowl spermatozoa has been studied in vitro under various modifications of pH, osmotic pressure, and chemical composition of diluents. The glucose and sodium chloride content of the diluents has been varied to give tonicities ranging between that of 0�45 and 1�8 per cent. sodium chloride. Tliese diluents were buffered with citric acid-disodium phosphate, sodium phosphates, or sodium carbonate-bicarbonate mixtures which were equally innocuous.
