Dari hasil destilasi didapatkan bilangan asam tidak jauh beda yaitu pada temulawak segar bilangan asamnya 1, sedangkan pada temulawak kering bilangan asamnya 2, At specific intervals, the strips were taken out and weighed and the weight loss was calculated. This may be due to an increase in moisture content after esterification. Biasanya berat jenis komponen terpen teroksigenasi lebih jurhal dibandingkan dengan terpen tak teroksigenasi.

Oleh karena itu minyak yang didapatkan akan berkurang. J Anal Appl Pyrolysis,73 2: Laporan Tptoa Simplisia Temulawak Documents. Published by Elsevier Limited. Karena sebagian komposisi minyak atsiri jika kontak dengan udara atau berada pada kondisi yang lembab akan mengalami reaksi oksidasi dengan udara oksigen yang dikatalisi oleh cahaya sehingga akan membentuk suatu senyawa asam.

Research progress in liquefaction technologies of biomass.

Characterization and Toxicity of Temulawak Curcuminoid Nanoparticles | Riki | Current Biochemistry

Temulawak merupakan tumbuhan semak tak berbatang. Corrosion properties of bio-oil and its emulsions with diesel. The purposes of this research is to find the best condition in extracting curcumin using multi stages extraction method to increase the efficiency rate in curcumin extraction.

At 70 C, conversion of acetic acid reached Article Tools Print this article. Setelah alat di gunakan, bersihkan permukaan prisma dengan alkohol. Variation in birch Betula pendula shoot secondary chemistry due to genotype, environment, and ontogeny. Chemical Industry and Engineering Progress,26 3: Extraction method which is used in extracting curcumin from turmeric is one stage extraction.

A schematic diagram of the fixed bed is shown in Fig.

Aktivitas Kombinasi Ekstrak Temulawak Documents. Nanoparticle technology for drug delivery; Polymeric nanoparticles for oral drug delivery.

Baunya harum dan rasanya pahit agak pedas. Both and NKC-9 resins exhibited high activities for esterification of acetic acid. Aktivitas antiinflamasi sediaan nanopartikel ekstrak kurkuminoid temulawak tersalut asam palmitat secara in vivo [Skripsi]. Dilution with small amounts of alcohol is known to stabilize bio-oil, and because of jrnal dilution effect by double volumes of methanol, the stability did not change significantly after esterification.

Semakin banyak kandungan airnya, maka semakin kecil nilai indek biasnya. User Username Password Remember me. A convenient general bioassay for active plant constituents. A serious phase separation was observed when bio-oil was heated, and the viscosity increased from Prisma ditutup rapat dengan sekrup, gerakan adilade mundur atau maju sampai terlihat batas terang dan gelap.

Bio-oil is not a highly dispersed system, and according to Garcia-Perez [21], bio-oil is a mixture of multiphase structure.

The particle size of nanoparticles obtained in this study was Prosedur analisa sifat kimia antara lain: Characterization indicators like polydispersity index, particle size, morpholgy, and entrapment ekstraski. A promising drug delivery system. Density was measured by Capillary-stoppered pyknometer method. Kurkumin loaded palmitic acid microparticles.

Pengamatan dilakukan secara visual langsung dengan eketraksi tanpa alat bantu. Temulawak segar dan tabel 2. Tsuda Akira and Gehr Peter. Biomass Chemical Engineering,40 suppl: The upgraded bio-oil didBased on the weight loss, as shown in Fig. Ekstraksi Kurkumin Dari Temulawak Documents. Progress in research of upgrading of pyrolytic bio-oil.

Penentuan bilangan ester dilakukan dengan pengujian blanko dan contoh sampel. Diharapkan untuk penelitian selanjutnya dihitung kadar air pada temulawak yang dikeringkan. Improved HPLC method for the determination of eksrraksi, demethoxycurcumin and bisdemethoxycurcumin. After esterificaiton on and NKC-9 resins, the acid numbers of model mixture were lowered by Comparatively, acid number determination by acidbase titration can accurately quantify the total amount of acids in bio-oil and is more suitable for evaluating the esterification of bio-oil.
