Abstract

The cytotoxic effect of herbal medicines has been examined using HeLa cells line (cervical cancer cell culture). The result showed that the LC50 value of buah merah [Pandanus conoideus Lam.], mahkota dewa [Phaleria macrocarpa (Scheff.) Boerl.] and temu putih [Curcuma zedoaria (Berg.) Roscoe] extracts were  421 µg/ml, 835µg/ml and 58,9 µg/ml after 24 hour incubation, whereas the LC50 of each extract were 276.79 µg/ml, 415,9 µg/ml and 29.19 µg/ml after 48 hour incubation respectively. The cytotoxic activity of temu putih [Curcuma zedoaria (Berg.)] extract to HeLa cells was stronger than buah merah [Pandanus conoideus Lam.] and mahkota dewa [Phaleria macrocarpa (Scheff.) Boerl.] extracts.   ABSTRAK Telah dilakukan penelitian efek sitotoksisitas ekstrak buah merah [Pandanus conoideus Lam.], mahkota dewa [Phaleria macrocarpa (Scheff.)

Abstract

Cancer was the third big death-caused disease in the developed countries. To overcome the disease, cancer patient can use combinaton of conventional and alternative therapy, such as using herbal   medicine. Nowadays there are many anti cancer herbal medicines in the market, one of which was BRM (Biological Response Modifier), that contain tansinon, polisaccharide, Lycium barbarum, Codonopsis pilosulae Radix extract, and marine algae extract. To investigate the cytotoxic effect of BRM, we  conducted cytotoxicity test in vitro using cancer cell culture. The test examined the activity of ethanol and aquoeus extract of BRM  on Ca Ski cells (cervix cancer cells), using Neutral Red Intake Cytotoxicity Test Method.  Results of the experiment revealed the LC50 of ethanol and aquoeus extract were 274.16 and 55.21mg/ml consecutively, after 24 hour incubation and 118.58 and 35.17 mg/ml after 48 hours incubation. It was concluded that ethanol and aquoeus extract of BRM had low cytotoxicity due to LC50 value greater than 20 mg/ml. ABSTRAK Kanker merupakan penyebab kematian ketiga terbesar di negara berkembang. Untuk mengatasi penyakit tersebut, penderita kanker dapat mengkombinasikan terapi konvensional dengan terapi alternatif, yaitu dengan menggunakan sediaan herbal. Saat ini banyak sekali sediaan herbal antikanker yang beredar di pasaran, diantaranya sediaan jadi BRM, yang mengandung tansinon, polisakarida, Lycium barbarum, ekstrak Codonopsis pilosulae Radix, dan ekstrak marinealgae. Untuk mengetahui efek sitotoksik sediaan tersebut maka dilakukan uji sitotoksisitas secara in vitro menggunakan biakan sel kanker. Pengujian sitotoksisitas ekstrak etanol dan air sediaan jadi BRM dilakukan terhadap sel Ca Ski (sel kanker serviks) meggunakan metode Uji Sitotoksisitas Ambilan Merah Netral. Dari penelitian ini diperoleh nilai LC50 ekstrak etanol dan air setelah inkubasi 24 jam masing-masing sebesar 274, 16 dan 55,21mg/ml, sedangkan setelah inkubasi 48 jam sebesar 118,58 dan 35,17 mg/ml. Hasil tersebut menunjukkan bahwa ekstrak etanol dan air sediaan jadi BRM mempunyai efek sitotoksik rendah karena memiliki nilai LC50 lebih besar dari 20 mg/ml.

Abstract

A method by high performance liquid chromatography for the analysis of acrylamide in potato chips, is reported. The retention time for the elution of acrylamide from the C18RP column ranged from 3 to 3,2 minutes, and the eluate was analyzed by UV-VIS detector. A linear response was found for the acrylamide standard tested within the concentration range of 0,8 – 10µg/ml and the corelation coefficient (r) greater than 0,999, with detection limit 0,06 ppm and quantitative limit 0,19 ppm. Sample preparation was performed by means of solvent extraction using dichlormethane and subsequent re-extraction of the organic solvent with water. This aqueous sample solution was found to be free of any interferences and gave acrylamide and recorveries higher than 90%.

Abstract

The aim of this research is to find the method for analyze glimepiride and itÂ’s metabolite. Glimepiride is the second generation of antidiabetic oral from the sulphonyl urea that works by stimulating the insulin secretion from beta cells of pancreas. Glimepiride is isolated from plasma the using chloroform. Using the high performance liquid chromatography method which include C18 reversed phase column, using mixture of methanol:water (50:50, v/v) as a mobile phase, flow rate 1.0 ml/minutes, detection at wavelenght 228 nm with photo diode array detector gives retention times of glimepiride in 17 minutes without any interference from endogen component of plasma and from itÂ’s metabolite. Linearity with added internal standard gliclazide was established for the range concentration 100-1000 ng/ml with coefficient of correlation (r) is 0.9977 and give the limit of quantitation of glimepiride in 50 ng/ml. The results of validation method fulfilled for the given criterias.

Abstract

Acrylamide is a chemical substance which derived from acrylonitrile, is the material used in polyacrylamide production. Recent research has found acrylamide is contained in some food, especially food is rich in carbohydrate and treated in high temperature (more than 120°C). Due to its nature, acrylamide is classified as a hazardous material to be contained in human’s food. The International Agency for Research on Cancer (IARC) has classified acrylamide into group 2A (probably carcinogenic for humans). Many methods that used to analyse the acrylamide in some foods with sophisticated equipment, and in department of pharmacy FMIPA-UI there were also develop the method with simple extraction and conventional HPLC

Abstract

Cilostazol is an antiplatelet agent with the mechanism of action by inhibiting phos-phodiesterase III (PDE III). Referred to Food and Drug Administration(FDA),cilostazol is a drug recommended to be bioequivalence (BE) studied. A high-perfor-mance liquid chromatographic (HPLC) method with ultraviolet detector for in vitro determination of cilostazol in human plasma had been developed and validated. Cilostazol and pioglitazone as internal standard were extracted from human plasma by protein precipitation method using methanol. The mobile phase consisting of ac-etonitrile-potassium di-hydrogen phosphate buffer 50 mM (40:60) was used at the flow rate of 1.5 mL/min on reversed phase C18 column (SunfireTM, 5 µm, 250x4.6 mm), and was detected at wavelength of 257 nm. Linearity was established within concentration range of 20-2000 ng/mL with coefficient correlation (r) was 0,9999. Accuracy (% diff) of this method was -14.67% up to 8.84% with precision (CV) being 0.98% to 4.93%, and absolute recovery was established to be 82.26% to 119.85%. Cilostazol in plasma was stable for 30 days in -200C storage.
