Objective: The goal of the project was to explore extracts from black tea leaves (Camellia sinensis Linnaeus) to prove it can give protection against ultraviolet rays (UV) in lotion preparation.Methods: Black tea extract was made in sunscreen lotion in oil in water (O/W) type emulsion using a combination of PEG-8 and beeswax as emulsifying agent 1, and combination of cetyl alcohol, ceteth-20, and steareth-20 as emulsifying agent 2. Evaluation of lotion including phytochemical screening of black tea leaf extract, measurement of sun protecting factor (SPF) value of extract black tea leaves, measurement of SPF preparation lotion sunscreen extract black tea leaves, physical observation of preparation, qualitative preparation evaluation using thin layer chromatography (TLC) and lotion security testing have been done to ensure the quality of lotions.Results: The result exhibited the effective SPF that was different to the sunscreen lotion F1, which contained 0.03% w/v and F2 which contain of 0.04% w/v black tea leaves extract with the point of SPF is 20.31 and 24.71 respectively. Both formulas fulfilled the requirements as lotion preparations and did not irritate the skin based on an irritation test on 20 volunteers.Conclusion: Formulas F1 and F2 can be applied as a sunscreen with good physical quality and is safe for topical use in lotion preparation.

Indonesia is quite well known as one of the countries that has tea plantations and uses its own production of tea. As a tea producing country, Indonesia has been able as a tea exporter. The most tea production in Indonesia is black tea product. Black tea products are produced from species Camellia sinensis Var. Assamica which undergoes an enzymatic oxidation process to fresh tea leaves. The most phenolic compounds contained in the black tea leaf are catechins, theaflavins, and thearubigin. The purpose of this study was to determine the phenolic total and catechin content of black tea products and acetone extracts produced by D'wan Tea (DT) and Bali Cahaya Amertha (BCA) plantations which located in Tabanan district, Bali. Determination of total phenol was carried out on black tea leaf products and acetone extract using the Folin-Ciocalteu method compared with gallic acid standards. Determination of catechin content was performed on fresh (before oxidized) tea leaves, black tea leaf products, and acetone extracts using the UV-Vis Spectrophotometry method at a maximum wavelength of 257 nm. The results showed that total phenol content of D'wan Tea black tea products (SDT) and Bali Cahaya Amerta (SBCA) were 1.50 ± 0.02 % mg GAE/g dan 0.97 ± 0.02 % mg GAE/g, respectively. Results of the total phenol content of D'Awan Tea (EADT) black tea acetone extract was 6.92 ± 0.12 % mg GAE/g, while the Bali Cahaya Amerta (EABCA) black tea acetone extract was 7.38 ± 0.07 % mg GAE/g. Catechin content from fresh leaf samples of D'wan Tea (SSDT), SDT, and EADT were 15.30 ± 0.22 % mg/g, 8.37 ± 0.13 % mg/g, and 37.45 ± 0.74 % mg/g. Catechin content of fresh leaf samples of Bali Cahaya Amerta (SSBCA), SBCA, and EABCA were 14.71 ± 0.28 % mg/g, 15.16 ± 0.58 % mg/g, and 35.66 ± 0.89 % mg/g. Total phenol content of DT black tea products is greater than BCA black tea products. DT black tea products appear to have decreased catechins in processing. In the processing of black tea it is necessary to decrease catechins content due to the formation of catechin polymers, namely theaflavin and thearubigin as a determinant of the quality of black tea.   Keywords: black tea, Camellia Sinensis, cathecin, total phenol.

Purpose – The purpose of this paper was to determine total polyphenols (TP), total flavonoids (TF) and (-)-epigallocatechin gallate (EGCG) in five commercial tea extracts and in their infusions at various temperatures (95-60°C) and brewing times (5-30 min). Design/methodology/approach – TP was determined by the Folin–Ciocalteu method, TF by the aluminium chloride colorimetric method and EGCG by HPLC method. Findings – The results showed that White tea – Silver needle had the highest content of TP and EGCG when extracted, but its infusions had very poor concentrations of these compounds. Green tea infusion was better source of TP and EGCG than white or black tea, although its extract did not contain a very high amount of TP compared to the latter two types. Black tea extract had a relatively high content of TP and TF in its extract. Its infusions as well contained higher concentrations of TP than white tea, but lower concentrations of EGCG than all studied teas. Originality/value – Increasing infusion time and temperature does not necessarily increase the concentration, according to the results. To the authors’ knowledge, this is the first report on comparing these types of tea, especially the white tea, with other well-known teas under various infusion conditions. The extraction of the white tea leaves was also not found in previous works.
