  • Salvia bucharica belonging to the family Lamiaceae (Labiatae), afforded a novel terpenoid (1) named as salvatrione. The structure of 1 was elucidated through extensive 2-D NMR experiments and the biogenetic pathway of 1 has also been proposed. On biogenetic grounds, 1 may be considered to be a pseudo-triterpenoid as it is derived from the coupling of mono/ diterpenic units and not from squalene.

  • 천연자원으로부터 얻어진 항암 또는 세포독성물질로는 주로 alkaloid, lignan, terpenoid, macrolide 등에 속하는 물질들이고 그 중 sesquiterpene lactone계열 화합물에서 세포독성 및 항종양 활성이 있는 물질이 다수 얻어졌으며 그 대부분은 국화과의 식물에서 분리 보고되고 있다. Achillea 속 식물은 국화과에 속하는 다년생초본으로 남한에는 톱풀과 산톱풀 2종만이 자생한다. screening 결과 이 두 식물에는 segquiterpene lactone 화합물과 Peroxide등 다수의 활성성분이 함유되어 있을 것으로 기대되어 본 연구에 착수하였다. 두 식물의 각 분획에 대하여 SNU-1(위암세포주)과 SNU-354(간암세포주)를 이용해 검색한 결과 두 식물 모두 MC ext.와 MeOH ext.에서 현저한 세포독성을 보였으며 현재 MC ext. 로부터 세포독성물질의 분리를 수행하고 있다. EtOAc ext.는 세포독성은 거의 나타내지 않았으나 flavonoid 성분이 다수 존재함을 확인하였으며 면역활성 및 enzyme inhibition등의 활성을 검토하고자 화합물을 분리하였다. 그 결과 톱풀로 부터는 luteolin-7-0-glucoside와 apigenin-7-0-glucoside를 그리고 산톱풀로부터는 luteolin-7-0-glucoside, apigenin-7-0-glucoside, luteolin, apigenin을 분리 확인 동정하였다.

  • From a chemist's perspective, Scarabaeidae is one of the most exciting group of insects to work on the isolation, identification, and synthesis of sex pheromones because-as opposed to Lepidoptera, which by and large utilizes straight chain alcohols, aldehydes, and acetates-the pheromonal chemistry of scarab beetles is remarkably diverse. While species in the subfamily Rutelinae utilize pheromone constituents, which are presumably fatty acid derivatives, the more primitive species in the subfamily Melolonthinae use phenolic, amino acid derivative, and terpenoid compounds. Here, I discuss the recent advances we have accomplished in the identification of scarab sex pheromones with especial emphasis on their chemical diversity. Also, I discuss the potential role of these sex pheromones in insect pest management. Field tests revealed that, in contrast to what has been frequently observed in the Lepidoptera, the higher the dosage of sex pheromone loaded in the traps the greater the capture of scarab beetles. These data suggest that mass trapping is more likely to be useful for scarab pest management than mating distruption.

  • Ligusticum tenuissimum belongs to Umbelliferae, and its root is generally used in headache, common cold and arthralgia L. We have extracted and isolated butylidene phthal ide, 3-butylidene-4,5-dihydrophthalide of phthalide group and l-limonene, etc. of terpenoid group from the root by ordinary method. In Ligusticum sinense, L. jeholense, L. tenuissimum, L. jeholense var. tenuisectum, and L. officinale etc., the components of cnidilide, ligustilide of phthalide group are common features and specific constituents in genus Ligusticum. Therefore comparing that there is no phthalide group in genus Angelica, we think it is able to classify the difference of genus between Ligusticum and Angelica of Umbelliferae in chemotaxonomy.

  • Steroid and terpenoid constituents of 3 species of genus Phytolacca have been examined by TLC. All contained ${\alpha}$-spinasterol, its glucoside and acylated glucoside, jaligonic acid and its methylester, esculentic acid and its methylester, and 10 phytolaccosides. Jaligonic acid was the major free triterpenoid and phytolaccoside E was the major saponin in all plants. Bayogenin, oleanolic acid, spergulagenic acid, acinosolic acid, hederogenin, and their derivatives contained in other Phytolacca spp. were not found in these plants.

  • Volatile flavor components of fresh, shady air dried, and presteamed shady air dried Chamnamul (Pimpinella brachycarpa) were collected by simultaneous steam distillation-extraction method, and essential oils were analyzed by gas chromatography-mass spectrometry (GC/MS). Twenty five, 17 and 23 volatile flavor components were identified in essential oils extracted from the fresh, shady air dried, and presteamed shady air dried Chamnamul samples, respectively; however, the kinds of individual components and its percent content of the total volatiles were varied depending on samples. The principal components of Chamnamul were isobutanal, trans caryophyllene, trans ${\beta}$-farnesene, and ${\alpha}$-selinene. Terpenoid compounds reached 44.11%, 33.91% and 72.63% respectively in fresh, shady air dried, and presteamed shady air dried Chamnamul.

  • 해조는 예로부터 특히 우리나라와 일본인들에 의해 임산부의 영양원, 조미소스, 미네랄, 식이섬유의 공급원으로서 애용되어 왔으며 최근에는 이들 해조성분이 가지는 생체유지기능에 관해서 점차 관심이 고조되면서 비식용해조를 포함한 다종의 해조내에 존재하고 있는 각종 기능성 물질에 대한 연구가 다각도로 진행되고 있다. 지금까지 해조에서 발견된 주요기능성 물질은 지방산 관련 화합물, 페놀류, terpenoid, 다당류, 아미노산류등이며 이들은 항균성, 항 바이러스성, 항종양활성, 항혈액응고성, 혈압조절등에 관여하는 것으로 알려지고 있다. 따라서 해조류는 고차기능을 가지는 식품으로서의 가치뿐 아니라 향후 의약품의 원료로서도 귀중한 자원이 될 것으로 기대된다. 본고에서는 이상 해조가 가지는 화학적 특성과 다종의 해조내에 존재하는 각종 생리활성물질에 대하여 지금까지 연구된 내용을 소개하고자 한다.

  • The ethanolic extracts of two shallow water sponge species collected from the Aegean Sea afforded thirteen terpenoids in total, two of which were determined to be new. The structure elucidation of the terpenoids was carried out by spectroscopic techniques and comparison with related authentic compounds. The terpenoids have also been assayed for antibacterial activity. This is the first report about the metabolites isolated from the marine sponges of the Aegean Sea in Turkey.

  • The chromatographic separation of the MeOH extract of the aerial parts of Solidago virga-aurea var. gigantea $M_{IQ}$ . (Compositae) led to the isolation of six terpenoids and four phenolic compounds, trans-phytol (1), ent-germacra-4(15),5,10(14 )-trien-1$\alpha$-ol (2), $\beta$-amyrin acetate (3), ent-germacra-4(15),5,10(14)-trien-1$\beta$-ol (4), $\beta$-dictyopterol (5), oleanolic acid (6), kaempferol (7), kaempferol-3-O-rutinoside (8), methyl 3,5-di-O-caffeoyl quinate (9), and 3,5-di-O-caffeoyl quinic acid (10). Their structures were established by chemical and spectroscopic methods. Compounds 4, 5, and 10 showed moderate cytotoxicity against five cultured human tumor cell lines in vitro with its E $D_{50}$ values ranging from 1.52∼18.57 $\mu\textrm{g}$/mL.L.
