Dissolution tests were conducted and the assay of meloxicam suppository X and Y using the method of meloxicam suppository High Performance Liquid Chromatography (HPLC). The purpose of this study to determine the dissolution rate of meloxicam suppository X and Y. Both samples received the same treatment that is performed at a temperature of 37 0C + 0.5 0C using 900 mL of dissolution media phosphate buffer pH 7.5 + 0.5. 10 mL samples were taken at minute 5, 10, 15, 20, 25, 30, 45, and 60. Each sampling was replaced with the same volume. Performed using the HPLC assay at λ 361 nm with a maximum 2.21 minute retention time and flow rate 1 mL/min. Regression equation obtained by y = 18401.7x + 6253.9 with a correlation coefficient (r) = 0.9937. The dissolution profiles showed that there was no significant difference in dissolution rate of meloxicam suppository X and Y. Key words: dissolution test, meloxicam, suppositories, HPLC

Identifikasi Gelatin dari Anjing Berdasarkan Profil Asam Amino dan Kemometrik

Gelatin adalah protein yang diperoleh dengan memanaskan kulit, tendon, ligamen, dan tulang dengan air. Gelatin banyak digunakan di beberapa produk makanan dan industri farmasi. Beberapa agama seperti Islam melarang pengikutnya mengkonsumsi produk makanan yang mengandung keturunan babi dan anjing, termasuk gelatin. Deteksi adanya kandungan nonhalal dalam produk pangan telah menjadi studi penting di banyak negara. Penelitian ini bertujuan untuk membedakan gelatin anjing dari kambing, sapi dan babi berdasarkan profil asam amino yang dikombinasikan dengan kemometrik dari komponen utama analisis (Principal Component Analysis/PCA). Pemisahan dan penentuan asam amino menggunakan liquid chromatography mass spectroscopy. Hasil penelitian menunjukkan bahwa lima kandungan asam amino tertinggi dalam gelatin anjing adalah asam glutamat, glisin, alanin, arginin, dan metionin. Parameter persentase tinggi puncak masing-masing asam amino dari masing-masing sampel dianalisis dengan PCA. Berdasarkan PC1 dan PC2, gelatin dari anjing, kambing, sapi, dan babi bisa dibedakan

Analisis Residu Pestisida Organofosfat Pada Simplisia Temulawak (Curcuma Xanthorrhiza Roxb.) Dengan Metode Spektrofotometri Visibel

Temulawak merupakan salah satu jenis tanaman obat yang mempunyai prospek cerah untuk dikembangkan. Tujuan penelitian ini untuk mengetahui ada tidaknya residu pestisida organofosfat pada simplisia temulawak dan melakukan validasi metode analisis residu organofosfat dengan metode spektrofotometri UV-Vis. Penelitian dilakukan dengan menggunakan metode destruksi basah, sampel yang diambil adalah simplisia temulawak yang diambil dari pasar Wage. Sampel kemudian ditambah asam nitrat pekat. Pengujian kadar organofosfat pada simplisia temulawak dilakukan dengan alat Spektofotometer UV-Vis Merk Shimadzu pada panjang gelombang 722 nm. Berdsarkan hasil penelitian pada simplisia temulawak terdeteksi adanya pencemaran organofosfat dengan kadar (72,678 g/g) dan hasil validasi analisis yang dilakukan didapat harga standard deviation (SD), relative standard deviation (RSD), dan ketelitian alat pada uji presisi alat pada sampel sebesar 1,4219 x 10-6; 0,2440% dan 99,997%. Nilai persen perolehan kembali (Recovery) rata-rata dan kesalahan sistemik pada uji akurasi sampel sebesar 87,72 % dan 12,28 % Uji linieritas didapatkan harga intersep sebesar 9,325.10-4, slope sebasar 0,020, koefisien korelasi (r) sebesar 0,9907 sehingga didapatkan persamaan regresi linier kurva baku y = 0,0429x + 0,0105 dengan limit deteksi dan limit kuantitasi 2,1468 ppm dan 7,1142 ppm. Berdasarkan penelitian ini dapat disimpulkan bahwa pada metode analisis identifikasi residu organofosfat pada simplisia temulawak menggunakan metode spektrofotometri UV-Vis adalah valid.

Analisis Residu Pestisida Organoklorin Pada Rimpang Kunyit (Curcuma Domestica) Secara M Spektrofotometri Ultraviolet Visibel

Ultraviolet-visible spectrophotometry can be used for determination of organochlorin in turmeric rhizome. This method is based on its complex formation between iron (III) dan thiocyanate ions and the absorption was monitored at 455.5 nm. The aim of this research is to know the validity of UV-Vis spectyrophotometry methods to determinate in turmeric rhizome. The result of analysis was mean organochlorin content in turmeric rhizome is 461.3 ppm. Result of validation analysis standard deviation (SD), coefficient variation (CV) and correctness of appliance at precesion test appliance are 2.4835.10-3, 0.778% and 99.9922% respectively. Method accuration test are recovery and systematically error are 108.984% and 8.984% respectively. For linearity test the equation of standard curve linear regression y=0.00345x + 0.127. Limit detection and limit quantitation are 21.565 ppm and 71.884 ppm respectively. Keywords: organochlorin, turmeric rhizome, spektrophotometry UV-Vis

Penetapan Kadar Tablet Ranitidin Menggunakan Metode Spektrofotometri Uv-vis Dengan Pelarut Metanol

Many people choose the branded drugs compared to generic drugs. They assumed that branded drugs are more effective than the generic ones. Drugs with similar therapeutic substance will have similar therapeutic effect depend on its concentration. For that reason, it's needed to determine branded drugs and generic drugs. UV-Vis spectrophotometry method can be used to determine Ranitidine in tablets. This method was based on chromophore and auxochrome in Ranitidine and its absorption at 326 nm. The aim of this research was to examine the ability of UV-Vis spectrophotometry method to determine Ranitidine in tablets and its validating methods. The result show that the mean weight of Ranitidine tablets sample is 150.44 mg/tablets. Results of validation analysis were standard deviation (SD), coefficient variation (CV), and correctness of appliance at precision test appliance equal to 0.07; 0.56 %; 99.44% respectively. The value of mean recovery and systematic error at accuracy test method equal to 108.39 % and 8.39 % respectively at 1000 ppm standard addition, 100.6 %; and 0.6 % respectively at 500 ppm standard addition, 100.67 % and 0.67 % respectively at 100 ppm standard addition. From the standard curve linier regression equation was obtained y = 0.045x + 0.068 (r equal to 0.9988). Limit of detection and limit of quantization that was obtained from this research equal to 0.6 ppm and 2.1 ppm respectively. Result of ANAVA test show that there is a difference between rate of Ranitidine at branded tablets and generic tablets. Keywords: Ranitidine, Tablets, Methanol, UV-Vis Spectrophotometr
