Alpinia species is one of the most important genera of the Zingiberaceae family. In Asia, they have been widely used as food and traditional medicines for centuries. This review focuses on their chemical constituents and their relevant biological activities with 252 references covering from 1955 to 2015. In total, 544 compounds were isolated from 35 Alpinia species. The major ones are terpenoids (207) and diarylheptanoids (143). The crude extracts and identified compounds exhibited a broad spect...

In order to get better knowledge about the volatiles produced by Xanthocyparis vietnamensis, a species recently discovered in Vietnam, its wood oil has been analyzed by a combination of chromatographic (GC, CC) and spectroscopic (GC-MS, 13C-NMR) techniques. Forty components that accounted for 87.9% of the oil composition have been identified. The composition is dominated by nootkatene (20.7%), 11,12,13-tri-nor-eremophil-1(10)-en-7-one (17.2%), γ-eudesmol (5.1%), nootkatone (4.7%), valencene (3.5...

Abstract The phytochemical investigation of whole plants of Ligularia pleurocaulis led to isolation of five sesquiterpenoids, including an eremophilenolide dimer named biligupleurolide, along with eight known sesquiterpenoids. Their structures were determined by spectroscopic methods including 2D NMR techniques, and the structures of biligupleurolide and ligupleurolide were confirmed by X-ray diffraction analysis. All of the isolated compounds were tested for their cytotoxic activity against thr...

The chemical composition of 45 essential oil samples isolated from the leaves of Polyalthia oliveri harvested in three Ivoirian forests was investigated by GC-FID (retention indices measured on two columns of different polarities), and by (13) C-NMR, following a method developed in our laboratory. In total, 41 components were identified. The content of the main components varied drastically from sample to sample: (E)-β-caryophyllene (1.2 - 50.8%), α-humulene (0.6 - 47.7%), isoguaiene (0 - 27.9%)...

Abstract Four new eudesmane-type sesquiterpenes thomimarines A–D ( 1 – 4 ) were isolated from the marine-derived fungus Penicillium thomii. Their structures were established based on spectroscopic methods. The absolute configurations of 1 – 4 were determined by time-dependent density functional theory (TD-DFT) calculations of ECD spectra. Inhibitory effects of compounds 1 , 2 and 4 on NO production in LPS-induced RAW 264.7 murine macrophages were evaluated.

Chemical study of four samples of Ligularia brassicoides collected in Sichuan Province of China afforded 18 compounds, five of which were new. LC-MS profiles were somehow similar to each other, although the compound ratio was slightly different. One of the new compound was a Diels-Alder adduct between franoeremophilan-10 beta-ol and methacrylic acid.

Commercial geranium oil samples, steam-distilled oils of authenticated plant samples, and a reference sample were investigated by GC/MS to determine the validity and applicability of a series of chemical and stereochemical tests that have been proposed in the literature to identify the country of origin, phytochemical identity or authenticity of geranium oils. The chemical tests evaluated include the ratio of the concentrations of geraniol to citronellol and the presence or absence of certain se...

The evaluation of 10 essential oils of geranium, Pelargonium graveolens (Geraniaceae), were all shown to have repellent activity against nymphs of the medically important lone star tick, Amblyomma americanum (L.). The biological tests were carried out using a vertical filter paper bioassay, where ticks must cross an area of the paper treated with repellent to approach host stimuli. One of the essential oil samples that repelled >90% of the ticks at 0.103 mg/cm 2 was selected for further fraction...

Abstract A novel norsesquiterpene ( 1 ), three new bisabolenes sesquiterpenes ( 2 – 4 ), along with 7 known compounds ( 5 – 11 ), were isolated from the rhizomes of Alpinia japonica . The structures of the new compounds were elucidated by analysis of spectroscopic data. The absolute configuration of C-1 in 3 was deduced via the circular dichroism data of the in situ formed [Rh 2 (OCOCF 3 ) 4 ] complexes. Inhibitory effects of the isolates on nitric oxide production in lipopolysaccaride-activated...
