    An alkaloid from Maclurodendron porteri has been isolated and characterized. Extraction process was conducted by acid-base extraction method followed by column chromatography. The structure was established by nuclear magnetic resonance spectroscopy and mass spectrometry. The compound was identified as haplophytin B which occurs commonly in the Rutaceae family. However, this is the first time this alkaloid was isolated and reported from the species. The compound showed no inhibition against Staphylococus aureus, Pseudomonas aeruginosa, Bacillus cereus and Escherichia coli and no cytotoxic activity against H199 and A549 cell lines.

    A new carbazole alkaloid, 3-carbomethoxy-2-hydroxy-7-methoxycarbazole, Clausine-TY (1), together with two known carbazole alkaloid, Clausine-H (2) and Clausine-B (3), were isolated from the ethyl acetate extract of the stem bark of the Malaysian Clausena excavata. The structures of these compounds were elucidated by spectroscopic analyses. The new carbazole alkaloid shows significant cytotoxicity against CEM-SS cell line.

    Leaf extracts of the Malaysian plant Aglaia laxiflora provided two cytotoxic compounds, a new rocaglaol rhamnoside (1), a known rocaglaol (2), new (but inactive) flavonol-cinnamaminopyrrolidine adducts (3-6), and their probable biosynthetic precursors (7 and trimethoxyflavonol). All structures were elucidated primarily by 2D NMR spectroscopy. The structure and stereochemistry of aglaxiflorin A (3) were confirmed by single-crystal X-ray crystallography.

    Goniothalamus macrophyllus (Blume) Hook. f. & Thoms. is a plant widely distributed in Malaysia. The aim of this study is to identify compounds from the roots of G. macrophyllus. The ground roots were extracted with aqueous methanol and partitioned sequentially with n-hexane, chloroform and butanol. Purification from this extracts afforded six compounds with two new compounds, namely goniolandrene-A (1), -B (2). The absolute configuration of goniolandrene B (2) was established by circular dichrosim. The compounds were cytotoxic against the P388 cells with IC50 values ranging from 0.42 to 160 μM. Goniothalamin (3) exhibited the highest inhibition of 0.42 μM.
