Abstract

Gandaria (Bouea macrophylla) plants contain antioxidant compounds that can reduce free radicals. Free radicals are one of the causes of various degenerative diseases. The purpose of this study was to determine the fraction that had the highest antioxidant activity, and to determine the secondary metabolites contained in the most active fraction of B. macrophylla seeds based on LCMS/MS analysis. Maceration of B. macrophylla seeds with ethanol solvent. Ethanol maserate was concentrated and fractionated by liquid-liquid extraction method using n-hexane, ethyl acetate and ethanol as solvents. Antioxidant activity was measured by the free radical scavenger method with 1,1-diphenyl-2-picrylhidrazil as a source of radicals and characterization of the secondary metabolites contained in the most active fraction using a Liquid Chromatography-Mass Spectrometer. B. macrophylla seed ethanol extract has a % yield of 31.75%. The ethyl acetate fraction of B. macrophylla seeds has the highest mass compared to other fractions and has strong antioxidant activity with an IC50 value of 2.95 ppm. The ethyl acetate fraction of B. macrophylla seeds contains tannins, phenolic, flavonoid dan alkaloid compounds. Based on the results of the identification of secondary metabolites by LC-MS/MS, the ethyl acetate fractions of B. macrophylla seeds contained phenylalalnine compounds.

Abstract

Melanin is the main pigment thfunctions to protect the skin from exposure to ultraviolet light, excessive melanin synthesis can cause skin hyperpigmentation. A. bilimbi and B. macrophylla fruits have bioactive compounds such as phenolics, flavonoids that function as antioxidants and tyrosinase inhibitors. This study aims to formulate a gel preparation of a combination of fruit extracts of A. bilimbi and B. macrophylla, test antioxidant activity using the DPPH method, and test tyrosinase inhibition enzymes. Three formulas were made, namely F0 (Basis), FI (50x extract), and FII (100x extract). Physical evaluation includes organoleptic, homogeneity, pH, adhesion, spreadability, viscosity, viscosity and irritation. Test of antioxidant activity and tyrosinase enzyme inhibition. Then the data were analyzed descriptively and statistically. The results of the evaluation of homogeneous preparations, dispersion, pH, viscosity, mandatory, meet the standards. Adhesion below standard, irritation test (mild irritation). The results of IC50 antioxidants were F0 (2,352 ppm), FI (1,448 ppm), FII (419,74 ppm) and gel brand x (77,429 ppm). The results of the tyrosinase inhibition test were the highest concentration of 10% F0 (7.828%), a concentration of 10% FI (18.245%), a concentration of 10% FII (25.814) kojic acid gel (brand x) as a comparison with a concentration of 10% (51.211%). The higher the concentration used, the greater the inhibition of the tyrosinase enzyme produced

Abstract

Isolation and identification of secondary metabolite compounds from stem bark of Bintangur (Calophyllum bicolor) have been reported. Isolation was carried out using the maceration method with 70% ethanol solvent and fractionation of the ethanol extract by column chromatography using n-hexane solvent. The n-hexane fraction resulting from column chromatography was subjected to gravity chromatography with the mobile phase n-hexane: ethyl acetate (8:2) producing isolate 1. The results of purification of isolate 1 using fast column chromatography with the mobile phase dichloromethane: methanol (1:1) and a UV light detector at ƛ 254 nm, compound 1 was obtained. Meanwhile, identification of compound 1 was carried out through UV-Vis spectroscopy, FTIR and LCMS analysis. The identification results of compound 1 using UV-Vis spectroscopy showed the presence of an aliphatic ring double bond chromophore (λmax 233.5; 295 nm). FTIR results indicated the presence of vibrations of the OH group (3417 cm-1), CH alkanes (2933; 2864; 1456; 545 cm-1), and C=C alkenes (1618 cm-1). Analysis results using LCMS showed a molecular ion peak at [M]+ m/z = 386.96 at a retention time of 11.6 minutes, indicating a molecular weight of 386 and a molecular formula (C27H46O) that corresponds to a terpenoid compound. Keywords: isolation, identification, terpenoid, bintangur (Calophyllum bicolor) AbstrakIsolasi dan identifikasi senyawa metabolit sekunder dari kulit batang bintangur   (Calophyllum   bicolor)   telah   dilaporkan.  Isolasi dilakukan dengan metode maserasi dengan pelarut etanol 70% dan fraksinasi ekstrak etanol dengan kromatografi kolom menggunakan pelarut n-heksana. Fraksi n-heksana hasil kromatografi kolom dikromatografi grafitasi dengan fase gerak n- heksana : etil asetat (8:2) menghasilkan isolat 1.
