Abstract. Sulasmi, Astirin OP, Widiyanti T. 2020. Short Communication: The most active fraction of red turi flowers (Sesbania grandiflora) on the cytotoxic activity of HepG2 cells. Nusantara Bioscience 12: 68-72. Red turi flowers (Sesbania grandiflora L.Pers) contain many chemical compounds with high bioactivity. One of the chemical compounds is flavonoid compound. Quercetin is a class of flavonoid compound. This compound is obtained by extraction with methanol as a solvent then it is partitioned by water and ethyl acetate as a solvent. The fraction obtained is given phytochemical tests, which is further test using Thin Layer Chromatography (TLC) to detect the quercetin compounds. The level of flavonoid is determined using UV Vis spectrophotometer. Water and ethyl acetate fractions are tested cytotoxically using the MTT method (3-(4,5-dimethyltiazol-2-il)-2,5-diphenyltetrazolium bromide) with ELISA Microplate Reader. This study aims to determine the most active fraction of red turi flowers on the cytotoxic activity of HepG2 cells, which are model cells for liver cancer. The results of water fraction do not contain quercetin compounds, with IC50 value of 961.11µg/mL. The ethyl acetate fraction contains quercetin compounds with total flavonoid equivalent quercetin of 1.76% b/b and IC50 value of 149.15µg/mL. Ethyl acetate fraction is more active than the water fraction with moderate cytotoxicity.

Diabetes is a metabolic syndrome characterized by high blood sugar levels or hyperglycemia.Alpha-amylase inhibitors can be used as an antidiabetic that controls postprandial hyperglycemia.Alpha-amylase inhibitors are found in plants as protein and non-protein bioactive content such as in lebuiseed. The purpose of this study was to determine the activity of alpha-amylase inhibition of the fraction ofethanol extract of lebui seed. This research was carried out by extraction of lebui seed and then fractionatedlebui extract to obtain n-hexane fraction (HF), ethyl acetate fraction (EAF), and water fraction (WF). Thefractions then tested to alpha-amylase inhibition activity in vitro by measuring the reducing sugar using3.5-dinitrosalicylic (DNS) reagent. Furthermore, the identification of the bioactive content of each fraction wascarried out using thin layer chromatography. The results of alpha-amylase inhibition activity test showed thatall fractions had the ability to inhibit alpha-amylase. The IC50 value of the n-hexane fraction, ethyl acetatefraction, and water fraction were 173.05 mg/ml, 9.98 mg/ml, and 137.19 mg/ml, respectively. Ethyl acetatefraction has the smallest IC50 value compared to other fractions. Based on the identification of the bioactivecontent, bioactive content that is only found in the ethyl acetate fraction but not in other fractions are tannins.Therefore, the chemical content in lebui seed which acts as an alpha-amylase inhibitor might be tannins.

Dates consisting of 90% flesh have been known to have various benefits, but the remaining 10% of them in the form of seeds has not been utilized optimally. The date palm contains a fairly high polyphenol compound, which can act as an antioxidant. This study aims to determine the antioxidant activity of methanol extract and fractionation of the extract of dates using the in vitro method of DPPH (1,1-diphenyl-2-picrilhidrazil). The date seeds are made into simplicia, macerated with methanol, and then the extracted methanol is gradually fractionated by n-hexane, ethyl acetate, n-butanol, and water. Each fraction and extract is phytochemically screened using the standard methods and its antioxidant activity is determined by DPPH method. Methanol extract, ethyl acetate, n-butanol, and water fractions contain tannins, flavonoids, alkaloids, and saponin, while the n-hexane fraction not contain phytochemical compound based on the phytochemical screening. The ethyl acetate fraction has the strongest antioxidant activity with the lowest IC50 value, that is equal to 3.72 ± 0.44 μg/mL, followed by methanol extract of 4.71 ± 0.64 μg/mL, n-butanol fraction of 6.62 ± 0.08 μg/mL, water fraction of 53.00 ± 18.96 μg/mL, and n-hexane fraction of 250.19 ± 9.69 μg/ mL, while the IC50 value of vitamin C as the positive control is 4.29 ± 0.74 μg/mL. Therefore, date seeds can be a source of natural antioxidants
