Triglicoside, phenol and delphinidine are compounds, which is found in the telangs flower(Clitoria ternateaL.) Telangs flower usually used by the local people as traditional medicinal plant for eyes conjungtivitis desease caused by Staphylococcus aureus bacteria. The aim of the study is to know the effectivity of telangs flower on conjungtivitis. The preparate of the extracts was prepared by maseration of 1,3 and 5%of telangs flower using 100ml aquabidest for 24 hours. The extract was then freeze dried at-15'C. The extract obtained was analised by Thin layer chromatography (TLC) using two types of eluent (butanol: asetic acid: water = 4: 4: 2) and eluent (chioroform: methanol =9:1).The spots were obserbed visually under ultraviolet ray at 254 nm and the spots were scrape of, then disolve in 10ml of aquabidest. The extract then tested by Staphylococcus aureus bacteria using the paper diffusion method. The results show that the extract of telangs flower 1% contains 0.014% of delphinide, 0.020% phenol, and 3% extract were 0.016% of delphinidine, 0.022% phenol, and 5% extract were 0.017% of delphinedine, and 0.026% of phenol. The phenol compound 0.026%showed an inhibition areas of 0.87mm as antibacterial while delphinedine is just a blue pigment of telangs flower.

To obtain the good quality of International Market Standard and better oil as raw material for rose oil synthetic where as the price of natural rose oil is much higher in price that of synthetic. The fractional distillation process was employed on crude Java Citronella oil grown in Sukabumi and Purwokerto to obtained the oil with international market quality and the oil fraction was used as basic material for rose oil synthesis. It was concluded that due to a high cost of the fractional distillation, it was unable to raise the economic added value of crude oil via quality improvement using this process except when the oil fraction was used as basic material for rose oil synthesis.

In order to improve the export quality of the Indonesian cloveleaf oil,the 66% eugenol containing essential oil produced by the water and steam distillation of old the ground clove leaves (Syzigium aromaticum L.)was deterpenated using two chemical methods of the deterpenation process,i.e. the method based on the formation of water-soluble alkali-phenolates to separate the water-insoluble non-phenolic constituents from the oil and that based on the extration of the soluble oxygenated constituent in dilute ethanol to separate the insoluble terpenes from the oil.Results of the experiments concluded that the method of deterpenation involving the formation of alkali phenolates was comparatively the most favourable process for carring out the quality upgrading of clove leaf oil, since it gave the terpeneless prodict with the highest content of eugenol (92%, compared to 72%obtained from the extration method).However, the method gave the terpene extract, as by-product,on the contrary,with the lowest content of betacaryophyllene (75%,compared to 80% obtained from the other method).

Tepung mokaf adalah tepung fermentasi ubi kayu yang dapat mengubah karakteristik dasar dari tepung ubi kayu menjadi lebih putih dan memiliki sifat gelatinisasi yang lebih baik. Untuk dapat memperoleh mutu tepung mokaf yang seragam diperlukan starter mokaf. Penelitian ini bertujuan untuk mempelajari proses pembuatan starter mokaf yang dapat menghasilkan starter mokaf yang dapat bertahan pada waktu penyimpanan 2 minggu pada suhu ruang dan 6 bulan pada suhu pendingin. Berbagai variabel yang dibuat pada penelitian ini antara lain starter yang dibuat dengan proses sentrifugasi dan dengan penambahan trehalose (RBa), starter yang dibuat dengan sentrifugasi dan tanpa penambahan trehalose (RBb), starter yang dibuat tanpa proses sentrifugasi dan dengan penambahan trehalose (RBc), serta starter yang dibuat tanpa sentrifugasi dan tanpa penambahan trehalose (RBd). Hasil penelitian menunjukan bahwa perlakuan terbaik pada pembuatan starter mokaf adalah dengan melibatkan proses sentrifugasi dan tanpa penambahan trehalose (RBb) dalam hal jumlah bakteri asam laktat yang dapat bertahan hidup serta ketahanan simpanannya. Dari hasil penelitian diperoleh starter RBa dan RBd tanpa proses sentrifugasi pada pembuatannya memiliki viabilitas awal 6,05 log CFU/g sampai dengan 6,94 log CFU/g. Sedangkan starter RBb yang menggunakan proses sentrifugasi pada pembuatannya memiliki viabiltas awal yang lebih tinggi yaitu 7,64 log CFU/g dan 9,01 log CFU/g dan starter RBc yang juga menggunakan proses sentrifugasi viabilitas awal 8,03 log CFU/g dan 8,69 log CFU/g. Penyimpanan starter pada suhu 4 0C mengalami penurunan viabilitas lebih kecil dibandingkan dengan starter yang disimpan pada suhu ruang sebesar 0, 62 siklus log selama 6 bulan penyimpanan.

Dewa leaf (Gynura pseudhochina (Lour) DC) often used as herbal tea to its benefit in reducing blood glucose content. One of the active compound in dewa is pyrrolizidine alkaloid. which is active against tumor. The aim of this research was to identify the active compound of pyrrolizidine in leaves of dewa green tea, black tea and dry powder which are resulted from the experiment. The analysis of pyrolizidine was done by quantitative and qualitative methods. The separation method used for the pyrrolizidine compounds was thin layer chromatograpy using methanol:water(85 : 15) as developing solvent. The determination of pyrrolizidine content was done by TLC scanner. The result showed that the RF value of dewa green tea is 0.34 relatively equal to the pyrrolizidine standard (0.360. While the Rf value of pirolyzidine compound in leaves of dewa black tea and dry powder was 0.42 and 0.41 significantly different from pyrrolizidine standard. The pyrrolizidine compound in leaves of dewa black tea and dry powder could not be detected quantitavely by TLC scanner because its concentration was too small, where as in leaf of dewa green tea the pyrrolizidine compound was detected 0.005%. So, it could be concluded that the contents of pyrrolizidine compound in leaf of dewa green tea was higher than pyrrolizidine content in black tea and dry powder of dewa leaf.

Clove leaf oil is one of the eugenol and beta-caryophylene source essential oils commonly use for chemicals,farmacies,fragrance,and food inductries. The problem of clove leaf oil is poor quality i.e. low eugenol content and dark brown colour,result in price low price.One alternative of increasing its quality and value is by chemical deterpenation method. This method include aging period treatment after reacted with sodium hydroxide for 12 and 24 hour. Eugenol and beta caryophilene content was analised by gas chromatogrphy.The eugenol content extracted from this method was compared with imported eugenol products i.e.containing 85%-99,2% with 70,09%(v/v) yield,aging of 12 hour result in eugenol content 80%-84% and 50.22% (v/v) yield.This method also result in beta caryophylene extrec as side product, aging of 24 hour result in the highest content of beta caryophylene i.e. 80%-85% with 25,22%(v/v)yield,whereas 12 hour aging result in beta caryophylene content of 62%-64% and 24,01% (v/v) yield.
