A new lignan from the stem bark of Roxb.

A new lignan, named fagraeanolide (), and 14 known compounds were isolated from the stem bark of Roxb. Their structures were determined by spectroscopic methods. Fagraeanolide is the first identified oxofurofuran lignan from the genus , while-boswelic acid () gentiogenol (), 3-(4-hydroxy-3-methoxyphenyl)-acrylic acid octacosyl ester () and pinoresinol () were isolated from this plant for the first time.

New flavonoids and xanthone from the stem bark of blume and cytotoxicity.

Three new flavonoids named artorigidinones A-C and a new xanthone named artorixanthone together with seven known compounds were isolated from the stem bark of Blume. Their structures were characterized by spectroscopic data. γ-Geranylapigenin exhibited cytotoxicity to a fibroblast-like cell line (SW1353) (IC < 0.

A new anthraquinone from Morinda elliptica Ridl.

A new anthraquinone, morinquinone, together with 18 known anthraquinones were isolated from the stems of Morinda elliptica Ridl. Their structures were elucidated on the basis of spectroscopic data. They each showed weak inhibitory activity against a susceptible strain of Staphylococcus aureus and a methicillin-resistant S.

A new bisanthraquinone and cytotoxic xanthones from Cratoxylum cochinchinense.

A new bisanthraquinone has been isolated from the stems of Cratoxylum cochinchinense together with vismiaquinone C and 16 known xanthones. Their structures were characterised by using spectroscopic methods. Two of the isolated compounds are modified xanthones (6 and 15) and exhibited strong cytotoxicity against human epidermoid carcinoma (A341: IC50 2.

A new chromone from the leaves of Melaleuca cajuputi Powell.

A new chromone, 5,7-dihydroxy-2 -(hydroxymethyl)-6,8-dimethyl-chromen-4-one, named melachromone, together with 12 known compounds, including chromones, anthraquinone, flavonoids, flavonoid glycosides, benzene derivatives, ellagic acids and terpenes, were isolated from the leaves of Melaleuca cajuputi Powell. Their structures were characterised by spectroscopic methods.
