α-Hydroxyisovaleric acid (Ac-Hiv) and α-acetyloxyisovaleric acid (Ac-Hiv) have been successfully synthesized through a diazotisation of amino acid using sodium nitrite with the catalyst of sulfuric acid and acetic acid, respectively. In the synthesis of Hiv, Zubia et al. (2005) mentioned that 3 equivalents of sodium nitrite for the reaction gave the hydroxy acid with a good yield. However, Cohen-Arazi et al. (2008) described that 6 equivalents of sodium nitrite resulted the highest yield. In present study, a variation of equivalents of sodium nitrite (3, 4, 5, 6 eq.) were trialed for the same method of synthesis. Through several experiments, we found that 6 equivalents of sodium nitrite were the best portion among all. This finding was applied into the synthesis of protected Hiv (Ac-Hiv) that was previously reported by Maharani et al. (2017) giving 63% yield when 3 equivalent of sodium nitrite was employed. By increasing the equivalent of sodium nitrite into 6 equivalents, the Ac-Hiv can be synthesized with an improved yield (71%).

Cervical cancer ranks as the 2nd leading cause of female cancer in Indonesia. One of healing methods is chemotherapy, but this method still has many side e ects and also expensive treatment. Therefore, natural products discoveries need to be developed due to its important role as an alternative for anti- cancer drug. The aim of this research was to get IC50 value from methanol, n-hexane, ethyl acetate, and n-buthanol from stem bark of A. minahassae dan A. simplicifolia. Stem bark of A. minahassae (1.6 kg) and A. simplicifolia (1.1 kg) was grounded by methanol and its extract is successively extracted by n-hexane, ethyl acetate, and n-buthanol. Their extract’s cytotoxicity was then evaluated against HeLa cell lines. This research showed that A. minahassae’s most cytotoxic extract against HeLa cell lines was n-hexane (IC50 = 27.4190 μg/mL) and n-buthanol (IC50 = 4.3924 μg/mL). Meanwhile, A. sim- plicifolia most cytotoxic extract extract against HeLa cell lines was n-hexane (IC50 = 23.3098 μg/mL). Key words: A. minahassae, A. simplicifolia, cytotoxic assay, HeLa cell lines

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.

Limonoids (tetranortriterpenoids) are triterpenoid compounds that lose four terminals in their structural framework. These compounds have a wide variety of structures and interesting activities including anti-inflammatory, anti-cancer, anti-tumor and anti-malarial properties. The purpose of this study was to find limonoid compounds from the Indonesian Chisocheton plant, and one of which is Chisocheton macrophyllus. The dried and powdered seeds of C. macrophyllus (4.5 kg) were extracted with methanol and partitioned successively with n-hexane, ethyl acetate and n-butanol. Evaporation of each extract resulted in the crude extracts of n-hexane (346.6 g), ethyl acetate (60.8 g) and n-butanol (14.6 g). The n-hexane fraction was subjected to a silica gel vacuum-liquid chromatography (VLC) column packed with silica gel 60 using gradient of n-hexane, ethyl acetate and methanol (10% stepwise) to afford thirteen fractions (A-M). Fraction F (4.4 g) was subjected to silica gel column chromatography using gradient of n-hexane and ethyl acetate (5% stepwise). Subfraction F5 (1.2 g) was chromatographed on a column of silica gel eluted with n-hexane: CH2Cl2: EtOAc (2:7.5:0.5) to give compound 1 (19.7 mg) and fraction H (1.8 g) was subjected to silica gel column chromatography using gradient of n-hexane and ethyl acetate (5% stepwise) as eluting solvent to give 2 (12.0 mg). Chemical structures of 1 and 2 were elucidated by spectroscopic methods and determined as 6α-acetoxyepoxyazadiradione (1) and Dysobinin(2). Dysobinin (2) showed weak cytotoxic activity against MCF-7 breast cancer cells with an IC50 value of 228.15 μM

Chisocheton balansae C.DC., is one of the Meliaceae family plants which is the endemic plants from Soputan Mountain, North Sulawesi, Indonesia. This study was aimed to determine the chemical structure of flavan-3-ol compounds from ethyl acetate extract of C. balansae C.DC stembark. Dried powder of C. balansae C.DC stem bark was extracted consecutively with n-hexane, ethyl acetate, and methanol solvents. Four flavan-3-ol compounds, named catechin (1), epicatechin (2), epigallocatechin-3-O-gallate (3), and epicatechin-3-O-gallate (4) were successfully isolated from ethyl acetate extract. The chemical structure of these isolates was determined by spectroscopic methods (1H-NMR, 13C-NMR, DEPT, and 2D-NMR) and comparison with previous reported spectral data. These compounds are first time reported from this plant.

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.
