Background: Lung cancer is the one of the leading causes of cancer death. However, current treatments for lung cancer are expensive and show negative side effects. Therefore, the study concerning natural anticancer from plants has intensified. Hibiscus sabdariffa Linn are Indonesian herb plants which have been consumed as a drink, are known to have anticancer activity against several cancer cell lines. However, its potential cytotoxic activity on A549 lung cancer cell line is still unclear. Objective: This study aimed to identify cytotoxic activity of Hibiscus sabdariffa Linn extracts on A549 lung cancer cell line. Materials and Method: Hibiscus sabdariffa Linn flowers from Tangerang, province of Banten, Indonesia, were macerated in three different solvents: ethyl acetate, ethanol, and n-hexane. Afterwards, cytotoxic activity of Hibiscus sabdariffa Linn extracts on A549 lung cancer cell line were evaluated using MTT assay. There were eight variety of concentration of the extracts, the experiment has been done triplicate for each concentration. The anticancer activity is expressed by IC 50 value. Results: Hibiscus sabdariffa Linn extracts in ethanol, ethyl acetate, and n-hexane showed IC 50 value of 374.01 μg/mL, 719.28 μg/mL, and 906.57 μg/mL respectively, in which indicated weak cytotoxic activity on A549 lung cancer cell line. Conclusion: Ethanol, ethyl acetate, and n-hexane extracts of Hibiscus sabdariffa Linn are potential to be further developed as natural anticancer agents. ABSTRACT SUMMARY Hibiscus sabdariffa Linn originated from Tangerang, Banten, Indonesia, showed cytotoxic activity on A549lung cancer cell line with IC 50 of 374.01 µg/mL, 719.28 µg/mL, and 906.57 µg/ mL.

Background: Cervical cancer is the cancer with highest prevalence and the leading cause of women death in Indonesia. Current treatments available for cervical cancer are chemotherapy, radiation, surgery, and nuclear therapy. Unfortunately, these treatments still have several limitations due to serious side effects, development of resistance, and very expensive price. Therefore, it is necessary to develop effective and low-cost therapy to treat cervical cancer. One of which is by utilizing natural sources available in Indonesia such as soursop (Annona muricata) leaves which has been used in folk medicine as a treatment for various diseases, including cancer. However, studies about its cytotoxicity against cervical cancer in Indonesia are still limited. Objective: The aim of this research is to analyze the potency of A.muricataleaves extracts originated from Indonesia as a novel alternative treatment for cervical cancer. Materials and method: A.muricata leaves obtained from Serpong, West Java, Indonesia were grounded and macerated in three different solvents with various polarity, namely ethanol (polar solvent), ethyl acetate (semipolar solvent) and hexane (non-polar solvent). Subsequently, the extracts were diluted into 8 various concentrations. Cytotoxicity of A.muricataleaves extracts against HeLa cervical cancer cells were determined by MTT assay and expressed by IC 50 value. Results: The results showed that three extracts of A.muricata have strong cytotoxicity against cervical HeLa cells. The highest cytotoxic activity was shown by etanol extract with an IC 50 of 35.51 µg/mL, followed by ethyl acetate (IC 50 : 5.91 µg/mL), and hexane (IC 50 : 8.39 µg/mL). Conclusion: A.muricata leaves extracts are potential to be developed as a novel alternative therapy for cervical cancer.

Objective: Hibiscus sabdariffa, known as Roselle, is a widely-cultivated herb in Indonesia and has been consumed as an herbal drink due to its medicinal properties. The purpose of this research is to identify the antioxidant activity and phytochemical profile of Hibiscus sabdariffa. Methods: The Hibiscus sabdariffa samples were extracted and macerated with three different organic solvents: ethyl acetate, ethanol, and n-hexane. These extracts were then analyzed using thin layer chromatography (TLC) and phytochemical tests to identify the extracts’ secondary metabolites. The extracts’ antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Results: The phytochemistry tests were positive for glycosides, alkaloids, steroids, triterpenoids, tannins, and flavonoids. The TLC analysis revealed that the extracts containing two to three organic compounds. The ethanol Hibiscus sabdariffa extracts with an IC50 value 103.63 ppm showed stronger antioxidant activity than the ethyl acetate extract. Conclusion: Ethanol Hibiscus sabdariffa extracts may be a potential source of natural antioxidant.

Objective: The genus Ruellia has been widely used in traditional and Ayurvedic medicine as an antioxidant. This study seeks to examine the antioxidant activity of the species Ruellia brittoniana. Methods: In this study, Ruellia brittoniana flowers were acquired from Depok, West Java, Indonesia. The flowers were cleaned and ground to form a powder, then dissolved in hexane, ethanol and ethyl acetate solvents. These three extracts were then tested for phytochemicals and thin layer chromatography (TLC) analysis. Ethanol and ethyl acetate extracts were also analyzed for antioxidants using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Results: Phytochemical results from the three extracts proved that Ruellia brittoniana contains flavonoids, alkaloids, tannins, glycosides and triterpenes. These results are comparable to the results from TLC analysis, which showed the samples contained 4–5 chemical components. Furthermore, the best antioxidant activity resulted from the ethyl acetate extract of the Ruellia brittoniana flower with an IC50 value of 68.42 ppm. Conclusion: An ethyl acetate extract from the Ruellia brittoniana flower can be used as a natural source of additional antioxidants.

Anticancer activity of the extracts of R. brittoniana flowers were evaluated by the MTT method. R. brittoniana flowers extracts were dissolved in Dimethyl Sulfoxide (DMSO) and then added to HeLa ABSTRACT Introduction: Cervical cancer ranks 4 th in terms of the mortality rates and incidence of all cancers in women (GLOBOCAN 2018). In last decade, there is a significance progress in cancer therapy followed by an increase in the cost of cancer treatment. Therefore, it is necessary to have therapeutic innovations that are expected to reduce the cost of cervical cancer therapy. One therapeutic innovation that is currently being intensively carried out is herbal medicine. Some researchers have found that some plant extracts have anti-cancer properties that can be an alternative treatment for cancer, such as some plants with the genus Ruellia, such as Ruellia tuberosa and Ruellia squarrosa. However, research on the anticancer activity of the species of Ruellia brittoniana, especially the flowers, is still limited. Objective: Aim of this study is to examine anti-cervical cancer activity of R. brittoniana flower. Methods: R.brittoniana flowers were obtained from Depok, West Java, Indonesia. The flowers are extracted gradually with n-hexane, ethyl acetate, and ethanol solvents. The extracts were evaluated for anticancer activity by MTT method. Result: IC 50 values for ethanol extract, ethyl acetate extract and n-hexane extract of R. brittoniana flowers are 116.55 ppm, 52.62 ppm, and 123.09 ppm, respectively, which indicating that ethanol extract has moderate anticancer activity, while ethyl acetate and n-hexane extract of R. brittonianaflowers have weak anticancer activity. Conclusion: Ethanol, ethyl acetate, and n-hexane extract of R.brittoniana flowers have a potential to become natural anti-cervical cancer.
