RESUMEN
Thymus daenensis Celak. subsp. daenensis is one of the endogenous Thymus species in Iran. The plant is traditionally used as carminative, digestive, antispasmodic, antitussive and expectorant in Iran. To study the Composition of the Volatile Oil of Thymus daenensis Celak. subsp. Daenensis. In this study, the hydrodistilled oil of the aerial parts of T. daenensis subsp. daenensis was analyzed using GC/FID and GC/MS. The result indicates that the oil contains over twenty-six components [99.7%]. The main components were thymol [74.7%], p-cymene [6.5%], B-caryophyllene [3.8%] and methyl carvacrol [3.6%]. This species has rich in phenolic substances specially thymol which might considered as a substitute for Thymus vulgaris

Several novel bioactive components isolated from Chinese medicinal plants will be presented. These include novel maytansinoid tumor, inhibitors, some new ent-kaurane and rosane diterpenoids from Mallotus anomalus Meer et Chun (Euphorbiaceae), as well asnovel insecticide, stemona alkaloids from Stemona parviflora C. H. Wright (Stemonaceae). Both are native plants of Hainan island, Chine. 2D NMR techniques such as mono and hetero-COSY, NOESY, COLOC as well as H-NMR line broadening effect were utilized for structure elucidation. The separation techniques, struture elucidations and bioassay results will be reported.
