  • Pharmacological activities of two sesquiterpenes, curzerenone(I), and curcumenol(II) isolated from the rhizomes of Curcuma zedoaria being used as an aromatic stomachic in Chinese medicines were evaluated in rats and mice. Curzerenone (I), at 100mg/kg, p.o. showed a potent protective effect against HCl-ethanol induced gastric lesion in rats, and curcumenol(II), at the same dose level showed a CNS depressant action characterized by a potentiation of hexobarbital(HB)-induced narcosis. Both compounds showed a moderate analgesic action but did not exhibit a hypothermic action even at 200mg/kg dose level.

  • Volatile components in Olive Flounder fed diets containing 0, 2,5, 5.0, and 7.5% yuza (Citrus junas Sieb ex Tanaka) for 4 months were investigated. Samples were extracted by solid-phase micro extraction and analyzed by gas chromatography/mass spectrometry. Among 89 compounds detected, 82 were positively identified. Volatile compounds of Olive Flounder fed the unsupplemented diet comprised 12 acids, 10 alcohols, eight aldehydes, five aromatic compounds, nine esters, 12 hydrocarbons, four ketones, two monoterpenes, and one miscellaneous compound. Compounds identified in Olive Flounder fed the yuza-supplemented diets consisted of 10 esters, 11 monoterpenes, 13 sesquiterpenes, and two miscellaneous compounds, with the other compounds being the same as in the control. The most abundant class of compounds in flounders fed the yuza-supplemented diet was the monoterpenes, which included limonene, $\beta$-terpinene, $\beta$-trans-ocimene, and $\alpha$-terpinolene. Of the 13 sesquiterpenes identified in flounder fed the yuza-supplemented diet, bicyclogermacrene was the major volatile compound followed by allo-aromadendrene, trans-caryophyllene, and $\delta$-cadinene. Bicyclogermacrene and germacrene D content increased significantly as the yuza supplementation increased.

  • Saussurea Radix, the dried roots of Saussurea lappa Clark (Compositae), has been used in oriental traditional medicine for aromatic stomachic. Present study was carried out for the anticancer effect of Saussurea Radix. Bioassay-directed fractionation of Saussurea Radix led to the isolation of two sesquiterpenes, dehydrocostuslactone (1) and costunolide (2). The structures of 1 and 2 were elucidated by spectral methods (MS, IR, $^1$H and $^{13}$C NMR). These compounds showed a potent cell proliferation activity against human breast cancer cell MCF-7 and MDA-MB-453.

  • Essential oil of the root of Angelica decursiva(Miq.) Fr. et Sav. (Umbelliferae) was investigated. Essential oil was obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. It was found to contain ten monoterpenes such as ${\alpha}-pinene$ (7.0%) etc. Three hydrocarbons, two aldehydes, three sesquiterpenes, two sesquiterpene alcohols, one aromatic compounds, one ketone, isobonyl acetate and two lactones were tentatively identified.

  • This study was carried out to select proper SPME fiber for volatile component analysis in Zanthoxylum schinifolium and Z. piperitum. PDMS, PDMS/DVB and CAR/PDMS were better for single standard absorption analysis. PDMS and PDMS/DVB showed similar results in comparison between direct injection and the mixture of 24 single standards as well as the mixture of 10 single standards. PDMS and PDMS/DVB were not different each other in absorption patterns between direct injection and headspace SPME regardless of split ratio of GC injection port. However PDMS/DVB rather than PDMS was effective in absorbing the sesquiterpenes within 30-40 minutes as using the SDE extracts from Z. schinifolium and Z. piperitum.

  • Objectives : To investigate the modern research achievements of agarwood and its association with the efficacy of herbal medicine based on the in vivo and in vitro activities of volatile compounds detected in agarwood. Methods : Databases such as PubMed and ScienceOn were searched for medicinal in vivo and in vitro activity studies on agarwood. They were categorized into "medicine and pharmacy" and "others not related to medicine and pharmacy," and the studies on medicine and pharmacy were organized according to active efficacy. The efficacy and virtue of agarwood as identified in the book (or herbal medicine/herbology) corresponded to modern medical terms and diseases in reference to the . Separately, the Gas Chromatography & Mass spectrometer (GC-MS) analysis results of agarwood from a total of 5 production areas of Aquilaria crassna from Vietnam, Indonesia, Malaysia, Myanmar, and Cambodia as identified in previous studies were consulted to search for research papers on the medicinal activity of the 13 compounds of the aromatic sesquiterpene family detected in agarwood, and they were categorized according to topic. Results : There were 123 studies on the medicinal activity of agarwood. Overall, 46 studies on single extracts of agarwood reported activities such as improving mental health, including anti-anxiety and stability, and antiallergic, antioxidant, antibacterial, and digestive system protective effects. In total, 59 papers on the activities of single compounds isolated from agarwood reported anti-inflammatory and mental health benefits. Separately, 13 compounds detected in agarwood, such as α-agarofuran and β-caryophyllene, were reported by 110 studies to have anticancer, stabilizing, antibacterial, and anti-inflammatory activities. There were also papers on the cultivation methods and resin formation conditions of agarwood trees unrelated to the efficacy of herbal medicine. Conclusion : Among the pharmacological papers, a total of 57 papers corresponded to the effects of agarwood in traditional herbal medicine, including 33 papers related to agarwood extracts and 24 papers analyzing 8 types of sesquiterpenes, such as β-caryophyllene and cedrol, from previous studies. Based on the research findings of each paper, it was possible to correlate the effects of agarwood in traditional herbal medicine with the achievements of modern pharmacological research. In addition, further research is anticipated in new areas related to traditional herbal medicine, including the improvement of mental health such as anti-depression, as well as activities related to anticancer, antioxidant, and hair growth.
