Abstract

Citrus amblycarpa (Hassk.) Ochse is an endemic Indonesian plant from West Java. This study aims to determine the chemical structure of the flavonoid compounds of C. amblycarpa peel ethanol extract and their antioxidant activity. Three flavonoid compounds, namely 5-hydroxy-3',4',6,7,8-pentamethoxyflavone (1), 8-hydroxy-3,3',4',5,6,7-hexamethoxyflavone (2), and 3',4',5,6,7,8-hexamethoxyflavone (3), were isolated for the first time from the ethanol extract of C. amblycarpa peel. Their chemical structure was determined by spectroscopic methods (MS, IR, 1H-NMR, 13C-NMR, and DEPT) and compared with previous reported spectral data. Furthermore, these compounds were evaluated for their antioxidant activity using the DPPH method. The results showed that 8-hydroxy-3,3',4',5,6,7-hexamethoxyflavone (2) has the highest antioxidant activity with IC50 value of 121.09 ± 0.24 ppm.

Abstract

Limonoid is derivatives of triterpenoid compound that have a wide variety of structures due to various ring-opening, rearrangements, and high-degree of oxidation. Limonoid is known as compounds that have wide-range of biological activities, including anticancer activity. This research was aimed to determine the chemical structure and cytotoxic activity of limonoid in the n-hexane extract of Chisocheton lasiocarpus fruit. Dried powder of C. lasiocarpus fruit was extracted using methanol followed by fractionated using n-hexane, ethyl acetate, and n-butanol. Five azadirone-type limonoids, 6α-(acetoxy)-14β,15β-epoxyazadirone (1), dysobinin (2), 7α-acetylneotricilenone (3), 6α-O-acetyl-7-deacetylnimocinol (4), and 7α-hyroxyneotricilenone (5), were isolated from the n-hexane extract of Chisocheton lasiocarpus fruit. The chemical structure of all compounds was identified by spectroscopic analysis, including 1D, 2D-NMR, IR, UV and HR-TOF MS as well as by comparison with previous reported spectra data. Compounds 1-5 were investigated from this plant for first time. The cytotoxic activity of the isolated compounds against MCF-7 breast cancer line were examined and the results showed that 7α-hyroxyneotricilenone (5) showed the moderate activity with IC50 values of 53 μM

Abstract

Aglaia is the largest genus of the Meliaceae family which contains terpenoid compounds. This type of compounds showed a diverse structures and biological activities that can be found in natural resources. Aglaia elaeagnoidea is a species from Aglaia genus that only has a few previous research. This study was aimed to isolate and determine the chemical structure of terpenoid compounds from the ethyl acetate extract of A. elaeagnoidea stem bark. Ethyl acetate extracts were separated and purified by various chromatographic techniques to obtain compounds 1-5. Compounds 1-5 were identified their chemical structures by spectroscopic methods (IR, MS, and NMR) and comparison with previous reported spectral data. Compounds 1 and 2 were identified as eudesmane-type sesquiterpenoids, 5-epi-eudesm-4(15)-ene-1β,6β-diol (1) and 6α-Hydroxy-eudesm-4(15)-en-1-one (2). Compounds 3-5 were identified as dammarane-type triterpenoids, 20S,24S-epoxy-25-hydroxydammarane-3-one (3), 20S,24S-epoxydammarane-3α,25-diol (4), and 3α-epi-cabraleahydroxy lactone (5). These compounds are first time reported from this plant. Compounds 1-5 were tested for cytotoxicity against HeLa cervical cancer cell and DU145 prostate cancer cell and as a result, compound 4 (20S,24S-epoxydammarane-3α,25-diol) showed the stronger activity compared to other compounds.

Abstract

Sesquiterpenoids are derivatives of terpenoid compound that have a diverse skeleton and broad spectrum of biological activities, particularly anticancer activity. This research reported the isolation and elucidation structure of sesquiterpenoid from Chisocheton lasiocarpus stem bark, as well as their cytotoxic activity. Four sesquiterpenoid compounds, namely eudesm-4(15)-ene-1β,6β-diol (1), allo-aromadendrane-10α,14-diol (2), allo-aromadendrane-10β,14-diol (3) and guaianediol (4), were isolated for the first time from Chisocheton lasiocarpus stem bark. The chemical structure of all compounds was identified by spectroscopic analysis, including IR, MS, 1H-NMR, 13C-NMR and DEPT, and compared with previous reported spectral data. The cytotoxic activity of the isolated compounds against MCF-7 breast cancer line were examined by using the resazurin method. The results showed compound 1 shown the highest cytotoxic activity with IC50 108.08 ± 0.58 µM.
