Abstract

Background: Epigallocatechin gallate (EGCG) is the most abundant green tea catechin with a powerful antioxidant effect to prevent cancer cells. EGCG in green tea solution is highly susceptible to degradation, this it is urgent to  increase the stability of EGCG by vitamin C addition. Vitamin C can regenerate radical EGCG to be normal EGCG. Objective: This research aim was to determine percent of decreased level of EGCG before and after vitamin C addition. Methods: This paper was focused on enhancing the stability of EGCG by 1 mg (GTVC1), 1.5 mg (GTVC2), 2 mg (GTVC3), 2.5 mg (GTVC4) and 3 mg (GTVC5) of vitamin C addition to 10 g/L of green tea solution concentration. Evaluations of EGCG were conducted at 0 days, 1 day, 2 days, 3 days, and 4 days of storage time. EGCG was analyzed using thin layer chromatography (TLC) densitometry methods. The stability of EGCG was determined by % of decreased EGCG. Results: Percent of loss of EGCG in GT, GTVC1, GTVC2, GTVC3, GTVC4 and GTVC5 after 4 days storage were 19.93%, 10.89%, 21.08%, 18.18%, 28.56%, and 9.76%, respectively. Conclusion: This study showed that in 4 days storage, the decreased level of EGCG in green tea solution with 3 mg of vitamin C addition (GTVC5) was 9.76% which was smaller than green tea solution without vitamin C addition (GT) which EGCG decreasing 19.93%.

Abstract

Background: Tea (Camelia sinensis) contains polyphenols including epigallocatechin gallate (EGCG) which is acknowledged to have strong antioxidant properties. However, its stability is strongly influenced by environment. In a neutral and alkaline environment, EGCG could undergo degradation and lose its antioxidant property. There are some researches about the effect of combination of green tea and other plants to their antioxidant capacity. Objective: The research aimed to investigate the effect of guava addition to EGCG content of green tea and their antioxidant activity. Methods: The concentration of EGCG was determined by chromatographic analysis using TLC scanner, meanwhile the antioxidant activity was evaluated by its ability in scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) using UV-Vis Spectrophotometer. Results: Among all the samples, formula 4 (2 parts of green tea and 3 parts of guava) gave the highest EGCG content (39.03 ± 3.65 mg/g). This was 37.5% higher than the control sample (28.39 ± 2.45 mg/g). Formula 4 also had the best antioxidant activity with IC50 of 1917.32±1.75 ppm, 19% lower than control sample (2356.46 ± 3.16 ppm). Conclusion: The addition of guava powder significantly increased the amount of EGCG in green tea extracts and their antioxidant activity.

Abstract

In several ASEAN countries, in vitro culture techniques are one of the cultivation technologies that applied in sustainable agriculture. This technology has been performed in response to obtain the secondary metabolite of epicatechin from Camellia sinensis L. However, The yield of epicatechin is remaining low than in the field production. To overcome this problem, phosphor inducers is desirable to be supplemented in the study. The young leaf shoots of C. sinensis L was sliced on a culture-filled bottle, the sliced part was re-cultivated in the same medium by supplementing of 2,4-D growth regulators, then the medium was optimized by phosphor inducer with range of concentartions 40-200 ppm. The callus formation was then evaluated using high performance liquid chromatography methods to obtain qualitative and quantitative data. The results showed that the yield of epicatechin was obtained to 11.75%, suggesting that the supplementing of phosphor inducers at cultivation of in vitro culture of C. sinensis L able to improve the production of epicatechin by in vitro culture technique.
