Abstract. Winata GM, Hardinsyah H, Marliyati SA, Rimbawan R, Andrianto D. 2024. Phytochemical compounds and antioxidant capacities of Abelmoschus manihot leaf extracts using different solvents. Biodiversitas 25: 942-949. Gedi (Abelmoschus manihot (L.) Medik) leaves are popularly consumed as a green vegetable by Eastern Indonesians. This work aimed to carry out the phytochemical compounds and antioxidant capacities of five extracts, i.e., water, 70% ethanol, absolute ethanol, ethyl acetate, and hexane of Abelmoschus manihot leaf. Qualitative analysis was done as a preliminary screening for flavonoid, tannin, saponin, alkaloid, triterpenoid, steroid, and quinone. Quantitative analysis determined the flavonoid, phenolic, tannin, quercetin, and steroid content. In-vitro antioxidant analysis was conducted to determine free radical scavenging activity and lipid peroxidation inhibitory activity. The results showed that flavonoid was only found in 70% ethanol extract; steroid was obtained in all extracts, while alkaloid, saponin, tannin, quinone, and triterpenoid were absent in all extracts. The results of the quantitative analysis showed that the highest flavonoid was in 70% ethanol extract (39.2 mg GAE/g), phenolic in ethyl acetate extract (34.792 mg QE/g), tannin in 70% ethanol (1.395 mg/g), quercetin in absolute ethanol extract (0.246 mg/g), and steroid content in hexane extract (201.948 mg/g). Half maximal inhibitory concentration (IC50) of each extract to inhibit malondialdehyde (MDA) formation was lower than free radical scavenging activity. The IC50 values of MDA formation in absolute ethanol and hexane extracts were 6.77 ppm and 7.67 ppm, respectively. The IC50 of vitamin E was 3.67 ppm. Further study is needed to determine the mechanism of Abelmoschus manihot leaf extracts as antioxidants used as a functional food.

Abstract. Winata GM, Hardinsyah H, Marliyati SA, Rimbawan R, Andrianto D. 2024. Nutritional composition of gedi (Abelmoschus manihot) leaves powder in comparison to common natural galactagogue plants in Indonesia. Biodiversitas 25: 2583-2589. Galactagogue is a substance believed to help initiate, maintain, and increase breast milk production. Low or no breast milk production and perceived insufficient milk are the most common reasons that cause a mother to stop breastfeeding earlier. To help this problem, natural galactagogue consumption is highly recommended. Gedi (Abelmoschus manihot (L.) Medik) plant is locally used in Indonesia as food ingredient and medicinal plant. The leaves have been believed for generations to increase breast milk production. This study aimed to evaluate the macro- and micronutrient content of gedi leaves powder, compared to torbangun (Coleus amboinicus) and katuk (Sauropus androgynous) leaves powder as common natural galactagogue plants in Indonesia. Clean fresh leaves were oven-dried and ground. Carbohydrates, crude fiber, protein, fat, ash, energy, water, vitamins A, B1, B2, B6, B9, C, E, and K, mineral calcium, iron, magnesium, sodium, zinc, phosphorus, and potassium were analyzed using standard methods. The analysis result showed that gedi leaves powder contained highest carbohydrate (51%), crude fiber (10.3%), vitamin K (1,110 µg/100 g), mineral magnesium (700 mg/100 g), sodium (89.6 mg/100 g), and calcium (2,671 mg/100 g) content, which were significantly different compared to torbangun and katuk leaves powder (P<0.05). Total energy (344 kcal/100 g), protein (25%), ash (13.6%), zinc (4.8 mg/100 g), potassium (2,314 mg/100 g), and iron (8.9 mg/100 g) content of gedi leaves powder were between torbangun and katuk leaves powder. This study showed that gedi leaves powder had a high carbohydrate, crude fiber, vitamin K, and mineral, especially calcium and magnesium, and sufficient protein and energy content, compared to torbangun and katuk leaves powder as common natural galactagogue plants in Indonesia. Further research in the extraction, bioactive compound, and in vivo study has to be carried out to scientifically prove the galactagogue effects of gedi leaf powder.
