Vitamin A Deficiency (VAD) is associated with significant morbidity and mortality from common childhood infections and is the world's leading preventable cause of childhood blindness. Studies showed that carotenoid is one of the promissed vitamin A sources. However the studies on carotenoid from yellow banana peel and its potential as a natural source of vitamin A has not been widely reported. This study was conducted to measure the blood serum retinol levels of rats after administration of β-carotene from yellow ambon banana peel. This was an experimental study with post test only control group design, with sample size of 18 rats with age 1 month, devided into 3 groups. The β-carotene dose administered based on the dose of red capsules vitamin A are (200,000 doses SI) for toddlers aged 12-59 months. Serum retinol levels were measured using a spectrophotometer according metide. This present study showed that the blood serum level in group treated with of β-carotene from yellow ambon banana peel (28.35 ± 1.61 mg/dL), was significantly different (p < 0.05) from that of control group (22.08 ± 1.35 mg/dL). The β-carotene from yellow ambon banana peel are potential as provitamin A.
Background: Carotenoid pigment is one of the promising sources of provitamin A because it has been shown to have capacity to be converted into vitamin A by the body. This present study aimed at evaluating the antioxidant activity in vitro using the DPPH and assessing the encapsulation of the crude carotenoid pigment extracted from Musa parasidiaca sapientum peel.Method: The total vitamin A carotenoid in the banana peel was assessed using the double beam Varian Cary 50 spectrophotometer at 470 nm. Then it was converted to microgram per gram of the banana peel using the NAS-NRC equation. The extraction was conducted using acetone. The antioxidant activity was assessed using DPPH (1.1-difenil-2-dipikrilhidrazil). The antioxidant activity of carotenoid crude extract was compared to that of marker â-karoten antioxidant (E-Merck, No. 1.02236). IC50 values were calculated using the regression formula. The dried carotenoid crude extract was encapsulated with dextrin filler.Result: The water content level of ambon banana was 50.68 % ± 3.35 %. The peel of the yellow ambon banana has a total carotenoid of 6.203 ± 0.004 μg/g. The converted carotenoid vitamin A was 124.06 ± 0.08 IU. The IC50 value of the yellow ambon banana crude extract was 2350.3 ppm meaning higher than the marker â-caroten (565.76 ppm). The encapsulation technique increased the pigment stabilization of the yellow ambon banana which will be used for vitamin A supplement.Conclusion: The crude extract of carotenoid pigment of the yellow ambon banana peel has an antioxidant potential although it is less efficient compared to that of â-carotene. The IC50 value of the crude extract of carotenoid pigment of the yellow banana ambon is 2350.3 ppm, higher than marker â -caroten (Sains Medika, 4(1):78-88).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
