Analysis of the synthetic sweetener sodium saccharin and sodium cyclamate in tea packaging has been done. The content of synthetic sweeteners are identified by color reactions and test microcrystals. The results obtained were compared with the reference standard material. Of the four samples tested, obtained three samples containing sodium cyclamate, while the other samples did not contain sodium cyclamate and sodium saccharin. Levels are determined by sodium cyclamate spektrofoto, ether UV-Vis. Levels of sodium cyclamate were obtained not exceed the maximum limit allowed by the Ministry of Health of the Republic of Indonesia is 0.3% for soft drinks.

The solid dispersion system of meloxicam-hydroxypropyl methylcelluloce (HPMC) 6 centipoise (cps) had been studied. The solid dispersion system was prepared by solvation method with several combination of meloxicam and HPMC were 1:1, 1:3 and 1:5. The physical mixture of meloxicam and HPMC with similar composition were used as standard. The powder of solid dispersion system and physical mixture were evaluated by X-ray powder diffraction, thermal (DTA), SEM and FT-IR spectroscopy analysis. The dissolution studies were carried out in USP type II apparatus. The result of X-ray powder diffraction analysis showed that the solid dispersion of meloxicam with HPMC decreased the drug crystallinity. The endothermic peak of meloxicam from solid dispersion products shifted to lower temperature and peak intensity decreased significantly. X-ray powder diffraction and DTA indicated transformation of crystalline state of meloxicam to amorphous one by solid dispersion with HPMC. SEM results showed the solid dispersion of meloxicam and HPMC has agglomerates form. FT-IR spectra indicated no chemical interaction between meloxicam and HPMC in the solid dispersion. The highest in dissolution rate was observed with solid dispersion products of meloxicam and HPMC with ratio 1:5 (94,083 %) compared to pure meloxicam and its physical mixture.

Publisher : STIFARM Padang

The influence of particle size toward the characteristics of Metronidazole tablets has been studied. Metronidazole that is used for first formua is not crushed, for the second formula is used Metronidazole powder cruhed for 30 minutes, and for the third formula is used Metronidazole powder that is crushed for 3 hours. The crushing process of the powder is done by using Ball mill. The result is analysed by SEM, DTA, FT IR, and particle distribution. DTA data (mettler Toledo) shows the changing of thermodynamic characteristics that occurs when the sample is given heat energy in form of melting shown by endoterm. From the three formula are made Metronidazole tablets by using wet granulation. The formulations of Metronidazole use mucilago gelatin as a binder, lactose as excipients, amylum as desintegrant and aerosil as a lubricant. Tablet evaluation involves the same size, same weight, the strength determining of level and dissolution. Dissolution test is done by using basket method and the level determined by the method of UV Spectrophotometer at the maximum absorption wavelength of 276.5 nm in HCl 0,1 N. The result of the assay formula 1 is 82,6248%, the formula 2 is 87.3086% and the formula 3 is 95.7037%. Result of dissolution measurement at 60 minutes showed that the average dissolution is 47.902%, 68,584% and 69.320%. The dissolution profile test uses HCl 0,1 N. The analysis of dissolution profile is done by the equality orde 0, orde 1, Higuchi and Korsmeyer peppas. Dissolution profile of Metronidazole tablets approach to Korsmeyer peppas.

Radikal bebas dari sinar matahari sepanjang waktu dimana kandungan radiasi sinar ultraviolet dapat menyebabkan penuaan dini pada kulit. Daun jeruk kasturi mengandung flavanoid yang berfungsi sebagai antioksidan alami yang dapat menangkal radikal bebas. Oleh karena itu dilakukan penelitian dengan tujuan untuk memformulasi sediaan krim antioksidan dengan menggunakan ekstrak daun jeruk kasturi. Ekstraksi dilakukan dengan metode maserasi menggunakan pelarut metanol. Ekstrak metanol yang diperoleh diformulasikan menjadi sediaan krim antioksidan dengan konsentrasi 9% dan 12%. Formula krim diuji fisik dan stabilitasnya dan dilakukan uji aktivitas antioksidan. Hasil penelitian menunjukkan bahwa sediaan krim memenuhi syarat kestabilan fisik seperti uji organoleptis, pH, homogenitas, daya sebar, stabilitas (cycling test), tipe krim, dan iritasi. Pada uji aktivitas antioksidan menggunakan DPPH sebagai radikal bebas menunjukkan hasil bahwa formula 1 dengan konsentrasi ekstrak 9% memberikan nilai IC50 sebesar 20,4729 μg/mL dan pada formula 2 dengan konsentrasi ekstrak 12% memberikan nilai IC50 sebesar 18,5499 μg/mL. Berdasarkan hasil penelitian dapat disimpulkan bahwa formula 1 dan formula 2 memiliki aktivitas antioksidan sangat kuat. Dari kedua formula tersebut formula 2 memiliki aktivitas antioksidan yang paling besar.
