Abstract

Green tea and its polyphenols have been studied extensively as cancer chemopreventive agents in recent years. However, the mechanisms of action are still not clearly understood. Some researchers suggest that immune system plays important role to destroy cancer cells. Because of that reason, the present study was designed to analyse the effects of oral administration standardized green tea water extract on increasing of IFN-g blood concentration and to elucidate possible mechanisms involved in the inhibitory action of the cancer development. Two groups (male and female) of 5 rats have given p.o. administration 1.25% of standardized green tea water extract and got 300 mg of (-)-epigallocatechin gallate (EGCG)/kg body weight, while two groups others (male and female) were used as control. We found that IFN-g blood concentration on male and female Wistar rat are significantly increase with 13.11% and 17.59%, respectively (p<0.05) by ELISA method, whereas control had no increase. These results indicate that standardized green tea water extract has possibility to prevent and suppress cancer development through enhancing IFN-g expression and other immunosurveillance component.

Abstract

Background: Green Tea Extract (GTE) is a natural antioxidant compound that can protect the skin from photocarcinogenesis (DNA damage due to ultraviolet exposure). GTE has low stability, which needs a delivery system such as Nanostructured Lipid Carriers (NLC) with decyl glucoside (DG) as a natural surfactant that at the right concentration can produce a significantly small particle size which can improve the stability of the NLC. Objective: To determine the effect of DG usage on the characteristics, physical stability, and irritability of NLC-GTE preparation. Methods: NLC-GTE preparation used the High Shear Homogenization (HSH) method with three formulas, which contained DG 2%, 2.5%, and 3% consecutively. Afterwards, the characteristic and physical stability tests were conducted using the thermal cycling method for three cycles with two different temperatures (48 hours/cycle, 2 - 8°C and 40°C). The irritability test used Hen's Egg Test on the Chorioallantoic Membrane (HET-CAM) method. Results: Characteristic test of organoleptic showed that all formulas were white, odorless, and had a semi-solid consistency. However, the pH, particle size, and polydispersity index values from all formulas were within the normal range of values. The physical stability test result showed that 3% DG was the most stable formula. This formula was within the non-irritating range of values in HET-CAM. Conclusion: NLC-GTE with an increased concentration of DG as a surfactant can improve the characteristics and physical stability of the preparation. F3 (3% DG) is the best formula compared to other formulas and indicates non-irritating in the HET-CAM test.

Abstract

Background: Green tea extract is a hydrophilic antioxidant that is difficult to penetrate. A nanostructured lipid carrier (NLC) delivers a system consisting of solid-liquid lipids that can improve penetration. Argan oil is a vegetable oil that can be used as a liquid lipid in NLC, reducing particle size and increasing penetration by hydrating the skin. Objective: To determine the formula of NLC green tea extract (NLC-GTE) with liquid lipid argan oil, which has good characteristics and is stable. Methods: Preparation of NLC-GTE used the High Shear Homogenization with solid lipids (cetyl palmitate-glyceryl stearate) - liquid lipids (argan oil) NLC-GTE1 (50:50), NLC-GTE2 (70:30), and NLC-GTE3 (90:10). Characteristic tests included organoleptic, pH, particle size (PS), and polydispersity index (PI). The physical stability test (organoleptic, pH, PS, and PI) used the thermal cycling method (3 cycles six days). Result: NLC-GTE1 – NLC-GTE2 has an odor of argan oil. NLC-GTE3 has odorless. NLC-GTE1 – NLC-GTE3 has a pH scale from 5.782-5.784; PS ranges from 359.73–432.56 nm; PI ranges from 0.175-0.257. The statistical analysis results showed no significant difference between NLC-GTE1 – NLC-GTE3 in pH and PI, there was a significant difference in PS NLC-GTE1; NLC-GTE2 against NLC-GTE3. Physical stability test NLC-GTE2 – NLC-GTE3 phase separation occurs. The statistical analysis results showed no significant difference in pH values NLC-GTE1 – NLC-GTE3 "‹"‹before and after storage; there was a significant difference in NLC-GTE3 before and after storage. Conclusion: NLC-GTE1 was a formula with good characteristics and stability.

Abstract

Background: The addition of alpha-lipoic acid in Nanostructured Lipid Carrier-Green Tea Extract (NLC-GTE) has potential to increase effectiveness of anti-aging preparations. It happened because alpha-lipoic acid can increase stability and antioxidant activity. Objective: Comparing the physical characteristics and stability of NLC-GTE with or without alpha-lipoic acid. Methods: NLC-GTE manufactured using the High Shear Homogenization method. NLC-GTE was divided into two formulas, without the addition of alpha-lipoic acid for F1 and with the addition of alpha-lipoic acid for F2. The characteristics and physical stability were tested, including organoleptic, pH, particle size, and polydispersity index. Stability test was held using the thermal cycling method. Results: Based on characteristic test, it was found that F2 had larger particle size value than F1. The average particle size value of F1 is 313.9 ± 0.76 nm and 423.4 ± 0.75 nm for F2. The F1 and F2 preparations had a polydispersity index value below 0.3, so they were homogeneous. The average pH value of F1 is 5.998 ± 0.01, and F2 is 4.798 ± 0.004. The physical stability test showed a difference before and after the sixth day in particle size and pH, but it was still in the range, so it was safe. However, there was a separation in F1 after day 6. Conclusion: Based on the characteristics and physical stability tests, F1 (without alpha-lipoic acid) and F2 (with alpha-lipoic acid) had differences in particle size and pH. From the physical stability test, it can be concluded that F2 is more stable than F1.

Abstract

This paper explains the development of a quick and easy gas chromatography (GC) approach to identify methamphetamine in urine. This research used gas chromatography with mass spectroscopy and a capillary column TG-5SILMS (5% phenyl methyl siloxane, 30 m x 0.32 x 25 m). The carrier gas flow rate was set at 1.0 mL/minute, the temperature inlet and detector had been set at 300°C, and the oven temperature was programmed to initiate at 50°C and held for 1.5 minutes before being raised to 300°C at a rate 40°C/minute and held for 3 minutes. Sample pre-treatment by modification of the QuEChERS method includes using a relatively large amount of inorganic salt, extraction volume and extraction cycle. The optimal conditions for processing a 400 uL urine sample were 160 mg magnesium sulphate, 40 mg sodium chloride, and 400 uL acetonitrile for organic solvent. According to the validation test, the detection limit for methamphetamine was 0.36 ug/mL; the quantitation limit was 1.09 ug/mL, and the calibration curve followed the regression line. y=1.0489x-3.7914, coefficient (r) was 0.9973. The recovery of the analyte spiked into urine at 5, 7 and 9 ug/mL on average was 100.5±2.33% for intraday dan 93.3±7.21% for interday. The precision was excellent, with an average coefficient of variation of 2.31%. The procedure was applied to four urine samples from drug users and the first abuser (25.51 ug/mL), the second abuser (15.05 ug/mL), the third abuser (17.72 ug/mL) and the last abuser (3.08 ug/mL) were all satisfactorily quantitated.

Abstract

Black tea (Camellia sinensis O.K var assamica) is one of the most widely consumed beverages by the public. Antioxidant compounds that can counteract free radicals are contained in Manalagi apple (Malus sylvestris Mill) juice and black tea. The purpose of this study was to prove that an increase in antioxidant activity and stability of black tea would be achieved with the addition of Manalagi apple juice. The DPPH (2,2-diphenyl-1-picrylhydrazyl) method was used to determine their antioxidant activities in this study. Antioxidant activity was measured in black tea at 0, 6, and 24 hours after the addition of Manalagi apple juice. Antioxidant stability of black tea was compared to black tea added with Manalagi apple juice. The results obtained showed that higher antioxidant activity of a mixture of black tea and Manalagi apple juice was indicated than the antioxidant activity of black tea alone. It was shown that a lower IC50 of a mixture of black tea and Manalagi apple juice was obtained compared to black tea. An increase in the stability of the antioxidants in the black tea solution was also observed with the addition of Manalagi apple juice, and the slope of the linear equation % inhibition of the mixture was found to be lower by about one third than black tea. Because of this reason, a slowdown in the degradation rate of the antioxidant activity of black tea is achieved by adding Manalagi apple juice.Keywords: Black Tea, Manalagi Apple Juice, DPPH, Antioxidant

Abstract

Teh adalah minuman terpopuler kedua setelah air putih di dunia. Konsumsi teh hitam di Indonesia lebih banyak dibandingkan teh hijau. Daun teh mengandung antioksidan yang dapat mencegah penyakit degeneratif seperti kanker. Teh hijau memiliki senyawa antioksidan total lebih banyak dibandingkan jenis teh lainnya. Antioksidan dalam teh terutama diperoleh dari senyawa katekin, sehingga semakin tinggi nilai total katekin maka aktivitas antioksidannya semakin besar. Berbeda dengan teh hitam yang mengalami proses fermentasi sebelum dikemas menjadi olahan teh, teh hijau tidak difermentasi. Ulasan ini menegaskan kembali aktivitas antioksidan teh hijau dibandingkan teh hitam berdasarkan total katekin dan nilai IC50 DPPH. Aktivitas antioksidan teh hijau lebih besar dibandingkan teh hitam. Nilai total katekin pada teh hijau lebih besar dibandingkan teh hitam, sedangkan nilai IC50 DPPH pada teh hijau lebih kecil dibandingkan teh hitam. Hasil tinjauan literatur ini merekomendasikan bahwa penelitian lebih lanjut dapat dikembangkan berdasarkan potensi aktivitas teh hijau dan teh hitam

Abstract

Tuberculosis is a global health problem, and there is even an increase in cases of multidrug-resistant tuberculosis in the world. Therefore, research is needed that can find new anti-tuberculosis drugs (OAT) that are more effective for tuberculosis treatment. In this study, the effect of (-)-epigallocatechin-gallate (EGCG) of tea leaves (Camellia sinensis) combined with the first-line OAT will be observed, in order to find out whether EGCG has anti-tuberculosis activity and can increase the potential of first-line OAT in-vitro. The anti-tuberculosis activity of EGCG was determined by broth dilution method using Middlebrook 7H9 media at concentration of 50, 100, 150, dan 200 ppm, then the potential of first-line OAT before and after combined with the EGCG was observed. The results showed that the activity of EGCG at concentration 50 ppm and 100 ppm could inhibit the Mycobacterium tuberculosis growth by 80%, at concentration 150 ppm by 90%, and at concentration 200 ppm by 100%. First-line OAT activity before combined with EGCG was ≥ 90% at 5 ppm rifampicin, 0.5 ppm isoniazid, 50 ppm pyrazinamide, and 5 ppm ethambutol. Whereas after combined with EGCG, the potential of each drug increased, marked by anti-tuberculosis activity achieved ≥ 90% at lower concentrations, i.e. rifampicin 0.5 ppm, isoniazid 0.25 ppm, pyrazinamide 20 ppm, and ethambutol 2 ppm. These results indicated that the potential of each first-line OAT increases after being combined with EGCG, and EGCG has potentiation effect when combined with those drugs. In conclusion, EGCG can increase the first-line OAT activity
