Structures of new sesquiterpenes from Curcuma comosa.
From the methanolic extract of the rhizomes of Curcuma comosa cultivated in Thailand, six new sesquiterpenes, (+)- and (-)-comosols (1, 2), comosones I (3), II (4), and III (5), and dimethoxycurcumenone (6), were isolated. Their structures were elucidated on the basis of chemical and physicochemical evidence.
متن کاملTwo new sesquiterpenes from Laurus azorica.
The structures of a new eudesmane sesquiterpene, lauradiol, and a new secoeudesmane, azoridione, have been determined by spectroscopic methods. These compounds and the known sesquiterpenic alcohols, clovanediol and caryophyllenol II, have been isolated from the aerial parts of Laurus azorica.

متن کاملNew sesquiterpenes from Euonymus europaeus (Celastraceae).
A new sesquiterpene evoninate alkaloid (1), and two sesquiterpenes (2, 3) with a dihydro-beta-agarofuran skeleton, along with three known sesquiterpenes (4-6), were isolated from the seeds of Euonymus europaeus. Their structures were elucidated by high resolution mass analysis, and one- and two-dimensional (1D and 2D) NMR spectroscopy, including homonuclear and heteronuclear correlation [correl...
متن کاملTwo New β-Dihydroagarofuran Sesquiterpenes from Celastrus orbiculatus Thunb and Their Anti-Proliferative Activity.
Two new β-dihydroagarofuran-type sesquiterpenes (1-2) were isolated and identified from the fruit of Celastrus orbiculatus Thunb, together with seventeen known compounds (3-19). The structures of the isolated new compounds were elucidated based on extensive spectroscopic analyses. The cytotoxic activities of the 19 sesquiterpenes on three cell lines, human acute promyelocytic leukemia HL-60, hu...
