The reseacrh about identification and assay of sodium benzoate content in fine milled chilli taken from three locations which were Pasar Ibuh Payakumbuh, Pasar Bawah Bukittinggi and Pasar Raya Padang had been done, two samples were taken from each location. It was found that three samples gave positive indication by esterification reaction to the presence of sodium benzoate in samples. Assay of sodium benzoate in samples after extraction with ether as a solvent were carried out using ultraviolet spectrophotometer. The benzoic acid content of the positive samples were found to be in the range of 0.811-0.976 g/kg. This amount of benzoic acid content fine milled chilli samples were below the maximum amount allowedaccording to the rule stated by to National Agency of Drug and Food Control Republic of Indonesia No. 36/2013 which was 1 g/kg, so it was safe to consume.

Research has been done on the determination of caffeine that leaves Kawa Coffee ( Coffea robusta Linden ex DE Wildem ) by using Soxlhetation method. Coffein from extraction purified by preparative TLC mobile phase solution chloroform : methanol ( 9:1 ).The constration of pure Coffein from preparative TLC has been determinedby using Spectrophotometer Uv-Vis T -70 .The result Coffea Kawa leaves (Coffea robusta Limden ex De Wildem ) is 0.7 % w/w

Penetapan Kadar Zink Pada Sediaan Farmasi Dengan Metode Kompleksometri dan Spektrofotometri Serapan Atom Dwi Dinni Aulia Bakhtra; Zulharmita Zulharmita; Valeria Pramudita

Research on the determination of zinc in pharmaceutical preparations have been carried out by complexometry and atomic absorption spectrophotometry. This research aims to determine and compare the levels of zinc in pharmaceutical preparations by complexometry method and atomic absorption spectrophotometry. Samples used zinc tablets were Zinkid® (PT. Indofarma), Zincare® (PT. Kalbe Farma) and Zinc generic tablets (PT. Kimia Farma). Zinc calibration curve at wavelength 213.9 nm used standard solution ZnSO4.7 H2O have correlation coefficient 0.9937 and linear regression equation y = 0.1124 + 0.4403x. Standard deviation 0.088. Detection limit 0.5996 mg/kg and quantitation limit 1.9986 mg/kg. The assay of zinc by complexometry method trademarks Zinkid® obtained zinc content 3.57 %, Zincare® 6.12 % and Zinc generic 3.68 %. While the method of atomic absorption spectrophotometry Zinkid® obtained zinc content 3.64 %, Zincare® 6.19 % and Zinc generic 3.72 %. Result of statistical analysis using t-test, it could be concluded that the method complexometry and atomic absorption spectrophotometry for the determination of zinc in pharmaceutical preparations dosage levels were not significantly different (sig.>0.05).

The fatty acid content analysis of avocados pulp taken from Batusangkar (Sumatra Barat) area had researched. Avocado were divided into 2 groups, that are group A : broaded in 3 days, group B : broaded in 5 days. Group A produced 149.274 g oils, whereas group B produced 169.598 g oils, analysis of avocado oil of group A by GC-MS showed the avocado oil components, namely acid miristat (2.44%), acid behenat (2.22%) and acid isopalmitat (10.97%), whereas the avocado oil components of group B are acid nonanoat (1.20%), acid miristat (2.80%), acid behenat (2.23%), acid palmitoleainat (7.91%), acid oleat (10.95%), acid oleat (28.69%), acid isopalmitat (4.77%).

Pembuatan Kalsium Glukonat Dari Batu Kapur Bukit Tui Padang Panjang Zulharmita Zulharmita; Sri Indah Kesuma; Fithriani Armin

A study concerning the manufacture of calcium gluconate limestone hill Tui Leopold. Previous limestone samples were identified and determined the levels of calcium. 1 g sample of limestone calcium levels obtained 36,0812 %. In the manufacture of calcium gluconate used limestone samples of 20 g were dissolved in 6 M HCl, filtered and the filtrate was added 6 M NH4OH to pH 10 . Then added gluconic acid 1 M. The precipitate is filtered, washed, dried in an oven at a temperature of 1050 C. The results obtained as 6,2084 g of calcium gluconate. Examination of limestone calcium gluconate include organoleptic examination, solubility, qualitative identification, examination and the melting point of the assay by the method complexometry. In the assay of calcium gluconate from the manufacture of natural limestone samples carefully weighed approximately 0,5 g , 1 g, and 2 g. Of the three differences in weight percentage of calcium gluconate calcium results obtained, weighing 0,5 g to as much as 62,2708 % , 1 g weight as much as 79,9048 %, while the weight of as much as 2 g 101,7232 %. From the results of the assay of calcium gluconate with a sample of 6,2084 g drying results have percentage 101,7232 % with the results of testing the melting point is 2000 C calcium gluconate. It can be concluded natural limestone hill Tui Leopold has a high purity calcium levels that can be made of calcium gluconate.

Pembuatan Kafein Salisilat Secara Semisintetis Dari Bubuk Kopi Olahan Tradisional Kerinci Sestry Misfadhila; Zulharmita Zulharmita; Deni Hardian Siska

The caffeine contained in coffee powder processed traditionally taken in Kerinci can be isolated, crystallized and made into a caffeine salicylate. Isolation of caffeine conducted through the coffee powder with water extraction, fractionation with methylene chloride, and crystallized using acetone and petroleum ether. The crystallization process is obtained of caffeine powder which is then reacted with salicylic acid, caffeine salicylate formed by using the solvent toluene and petroleum ether. Identification of caffeine powder and caffeine salicylate include: organoleptic, melting range, color reaction, the ultraviolet spectrum, infrared spectrum and thin layer chromatography. The identification caffeine results meet the requirements listed in the Indonesian Pharmacopoeia V edition of 2014. The results of determining the wavelength of maximum absorption of caffeine powder isolation results was 276 nm, caffeine salicylate 243 & 307 nm. Rf values obtained from thin layer chromatography test for caffeine is 0.30 and caffeine salicylate 0.36.
