Abstract

Free radical effect is one of many factors that can cause coronic desease, heart coronary desease, diabetes militus.  Beans plant (Phaseolus vulgaris L.) countant antioxidant compound. Antioxidants could inhibit oxidation reaction, that is cousing free radical compounds. The objective of this research was to determine the potential of bean extracts as an antioxidant. DPPH method was used to measure antioxidant activity, absorbances was measured using UV-Vis spectroscopy. Scrining phytochemical used to identified secondary metabolites in samples. The result showed IC50 1268.18; 2512; 1698.18 and 4442.75 μg/mL for all variety of stroge (less 1, 1, 2, 3 months) and IC50 control BHT was 1.744 μg/mL. Extract of bean powder sample classified as very weak antioxidant activity, variety of storage could effect to antioxidant activity. Phytochemical screening results obtained flavonoids, phenols, alkaloids, saponins, steroids and terpenoids present in the sample, while tannin are not included in the sample

Abstract

Research has been carried out on the analysis of physic properties of green bean extract powder (Phaseolus vulgaris L). This study aims to determine the physical characteristics of the bean extract powder that has been stored in a predetermined time variation. The physic properties tested included water content, solubility and organoleptic tests. The results of the sample water content test with storage variations of less than 1, 1, 2 and 3 months respectively were 5.55%, 2.86%, 3.83% and 3.54% and the solubility was 42.67%, 33, 84%, 44.51% and 34.33% for Artificial Gastrid Fluid (AGF) solvents and 31.79%, 35.08%, 43.24 and 34.52% for Water solvents. The results of the organoleptic test showed that the color of the bean extract powder sample with a storage time of ± 2 months was the most preferred by the panelists, Fresh samples had the highest average scores for taste and aroma, of the panelist samples preferred the samples that had been stored for ± 3 months
