Introduction: Black glutinous rice (Oriza sativa var glutinosa) and green tea (Camelia sinensis) are plants that are useful for moisturizing the skin. The purpose of this study was to obtain the best formulation of peel-off gel mask preparations from black glutinous rice and green tea extract. Method: The gel mask formulation was made on the basis of variations in the concentration of Hydroxy Propyl Methyl Cellulose (HPMC) of F1 (2,5%), F2 (3%) and F3 (3,5%) with evaluation including organoleptic tests, pH, viscosity, homogenity, dispersity test, and drying time at temperatures of 4oC, 25oC, 40oC for 28 days. Results: The evaluation results of the three formulations met the requirements for a good peel-off gel mask. pH results are between 4.6-5.5 which is still in the standard range of 4.5-6.0. The results of the viscosity test are 6.500-12.166.7 cps which are in the range of 6.000-24.000 cps, the dispersion area meets the requirements of 5-7 cm, the result of the drying time is 15-22 minutes which are in the range of 15-30 minutes. Conclusion: The conclusion of this study was that F1, F2, and F3 met all the requirements for peel off gel masks by storing at temperatures of 4oC, 25oC, 40oC for 28 days.

Tea Extract

Green tea (Camellia sinensis) is one of traditional plants that have the potential as an anticancer. The sample used in this research commercial green tea extract. The purpose of this study was to test the antiproliferation activity of green tea extract on breast cancer cell MCM-B2 in vitro. Green tea extract fractionated using three solvents, ie water, ethanol 70%, and n-hexane. Extract and fraction of green tea water have value Lethality Concentration 50 (LC50) more than 1000 ppm. The fraction of ethanol 70% and n-hexane had an LC50 value of 883.48 ppm and 600.56 ppm, respectively. The results of the phytochemical screening of green tea extract are flavonoids, tannins, and saponins, while the phytochemical screening results of n-hexane fraction are flavonoids and tannins. Antiproliferation activity was tested on breast cancer cells MCM-B2 and normal cells Vero by trypan blue staining method. The highest MCM-B2 cell inhibitory activity was achieved at a concentration of 13000 ppm green tea extract and 1000 ppm of n-hexane fraction, 59% and 59%, respectively. The extract and n-hexane fraction of green tea are not toxic to normal Vero cells characterized by not inhibiting normal cell proliferation.

Objective: Investigating the effect of green tea extract (GTE) on the testicular damage induced by cadmium chloride CdCl2 in male rats. Design: Randomized controlled study. Animals: 40 male Wistar rats. Procedures: Rats were randomly divided into four groups: A) control group (each rat daily received pellet diet); B) GTE group each rat daily received pellet diet as well as 3 ml of 1.5 % w/v GTE, C) CdCl2 group each rat was I/P injected a single dose of 1 mg/kg CdCl2, then daily received pellet diet, and D) CdCl2+GTE group each rat was I/P injected a single dose of 1 mg/kg CdCl2 then daily received pellet diet as well as 3 ml of 1.5 % w/v GTE. After 30 days, blood samples were collected for hormonal assays (testosterone, FSH, and LH). In addition, both testes were collected; one of them was used for quantification of 17-beta hydroxysteroid dehydrogenase III (17β-HSDIII) gene expression using a real-time PCR. The other testis was used for determination of catalase and reduced glutathione; GSH, Nitric oxide (NO) and malondialdehyde (MDA) levels. Results: CdCl2 decreased serum testosterone levels and its synthesis pathway (17β-HSDIII testicular gene expression). While antioxidants catalase and GSH were reduced, oxidants MDA were enriched in the testes of CdCl2-poisoned rats. This CdCl2-promoted testicular dysfunction was corrected via the administration of GTE to male rats. Conclusion and clinical relevance: GTE could be used as a remedy for protecting against CdCl2-induced testicular damage in male rats.
