Abstract

ABSTRACTTwo isomer flavonoids, 7,4´-dihydroxyflavanon (1) and 7,4´-dihydroxyisoflavanon (2) were isolatedfrom the bark of Sesbania grandiflora L. Their structures were determined based on spectroscopicdata such as UV, IR, MS, 1D and 2D NMR.Keywords : Sesbania grandiflora L., flavonoid, 7,4´-dihydroxyflavanon, 7,4´-dihydroxyisoflavanonABSTRAKDua isomer senyawa flavonoid, 7,4´-dihidroksiflavanon (1) dan 7,4´-dihidroksiisoflavanon(2) telah berhasil dipisahkan dari batang Sesbania grandiflora L.

Abstract

Infection with the dengue virus by the Aedes aegypti mosquito vector is in the form of dengue hemorrhagic fever (DHF), which can cause a decrease in platelets and even death. The parasitic drug niclosamide, which is effective against dengue virus serotype 2 (DENV-2) is used to prevent further dengue virus infection. Many tests were carried out using inhibitors such as doxorubicin (SA-17), glycoside inhibitors in the form of deocynojirimycin (DNJ) and castanospermine (CSP), carbohydrate-binding agents (CBA), and the use of heparan sulfate aimed at inhibition of the adsorption process and replication process, as well as improper protein folding to prevent the conformation of virus merger. The elimination process can also be carried out using antiviral compounds found in the leaves of Psidium guajava and Carica papaya, which have inhibitory activities of 92.6% and 89.5%, respectively; propyl gallate, with a percent inhibition of dengue virus envelope protein serotype 2 of 53-9.85%; isobutyl gallate, with CC50 values of 167.19 g/mL and an inhibitory value (IC50) of 4.45; Cissampelos Pariera Linn methanol extract, with progressive inhibition as the Cipa extract concentration increased with an IC50 value of 6.1μg/ml Preventive methods are also carried out in several ways, namely by utilizing hydrophobic liquid in the form of silicone oil (low-viscosity polydimethylsiloxane, or L-PDMS), the use of eave tubes in home tubes inserted with insecticides, and utilizing ultrasound with a frequency of 100 kHz and 90 dB to repel mosquitoes carrying dengue virus vectors.

Abstract

Calophyllum incrassatum is one of the plant species of the Calophylloceae family and is found endemic in Kalimantan and Sumatra. This study aims to isolate chromanone acid compounds from the stem bark of C. incrassatum and determine the relationship between structure and activity against murine Leukemia P-388 cells. The extraction method used was maceration using methanol solvent, partitioned with n-hexane and ethyl acetate solvents. Separation and purification of n-hexane and ethyl acetate extracts by vacuum liquid chromatography, pressed column, and radial. Two chromanone acids derivatives, isoapetalic acid (1), and methyl isoapetalic (2), have been successfully isolated from the stem bark of Calophyllum incrassatum. The structures of the two compounds were identified and elucidated using spectroscopic techniques such as UV, IR, and 1D and 2D NMR. The cytotoxic activity against murine leukemia P-388 cells of compounds 1-2 showed IC50 values of 8.51 and 1.47 µg/mL, respectively, and compound (2) exhibited high cytotoxic activity
