Abstract

Sesquiterpenoid is a class of terpenoid compounds that have the most abundant diversity of structures and biological activitiesthat can be found in natural resources. Tropical plants are main source of sesquiterpenoid compounds such as Aglaiagenus belong to Meliaceae family. A. harmsianais a species from Aglaiathat only has few previous researchs.  Therefore, the purpose of this study was to isolate and determine the structure of sesquiterpenoid compounds from stem barkA. harmsianaalong withtheir cytotoxic activity against MCF-7 breast cancer cells. The isolation process begins by extracting powder from A. harmsianastembark using n-hexane, ethyl acetate and methanol. All extracts were evaluated for their cytotoxic activity against MCF-7 breast cancer cells, and n-hexane extractsshowed significant cytotoxic activitywith IC50values of 117.86 µg/mL. Therefore, n-hexane extracts were further separated and purified by various chromatographic techniquesto obtain compounds 1and 2. Compounds 1and 2were elucidated their chemical structures by spectroscopic methods includingIR, NMR, and MS as well as bycomparison of data with literatures and identified ascaryophyllene-typesesquiterpenoids, β-caryophylleneoxide (1) and senecrassidiol (2). Compounds 1and 2were submitted for cytotoxic eveluation on MCF-7 breast cancer cells and as a result, β-caryophyllene oxide (1) showed the stronger activity compared to senecrassidiol (2). These finding indicatedthat the cytotoxic activity of caryophyllene-typesesquiterpenoid areinfluenced by the presence of double bonds and configuration of methyl groups.

Abstract

The Aglaia genus belong to Meliceae family is unique plant species because the presence of rocaglate and rocaglamide which is so far isolated only from Aglaia genus, indicate that type of this compound as a chemical marker for the genus of Aglaia. This type of compound known to have strong activity, such as insecticide and cytotoxic. This study describe the isolation, structure elucidation, and cytotoxic activity of an isolated rocaglate compound. Dried stembark of A. argentea extracted with methanol and partition between n-hexane, ethyl acetate, and n-butanol, respectively The extracts were tested against P-388 murine leukemia cells and the ethyl acetat showed strongest activity with IC50 value of 15.5 mg/mL. The ethyl acetate then was separated and purified with chromatography technique to obtain isolated compound 1. The chemical structure of isolated  compounds were elucidated by spectroscopic methods including one and two-dimensional NMR as well as high-resolution mass spectrometric analysis and identified as a methyl rocaglate. Compound  1 showed strong cytotoxic activity with an IC50 value of < 0.1 μg/mL.
