PENGARUH PERLAKUAN AWAL DIC PADA PENGERINGAN DAUN SALAM (Eugenia polyanta Wight, Walp) TERHADAP EFISIENSI EKSTRAKSI DAN KECUKUPAN KANDUNGAN SENYAWA FENOL TOTAL (Phenol Content).

Abstract

The development of science in every field and the finding of new medicines are growing very fast, as well as the use of herbal medicines. One of the many herbal plants is Salam (Eugenia polyanta (Wight), Walp). Judging by the great prospectiveness of the Salam leaves, the government through the Indonesian FDA has included the Salam plant as one of the nine excellent plant, so that it can be developed as a Phytopharmaceutical. The phytopharmaceutical has to follow certain prerequisites, one of them is it has to be in the form of standardized extract or powder.
 In order to produce extract, the raw material is preferred in a dry state, because the water content can be reduced, so that it can minimized the enzymatic and hydrolytic reaction.
 In this study, the effect of pre drying by Détente Instantanée Contrôlée (DIC/Instantaneous Controlled Pressure-Drop) method is carried out, as it will opened up the pores of the plant cells, so that the vaporization will be accelerated and the the thermal degradation can be minimized. Eleven parameters have been studied. It can be concluded that based on the drying times and the Total Phenol Content, the parameter 1,9 bar and 10,86 second is the optimum parameter of the DIC.
