Brominated Selinane Sesquiterpenes from the Marine Brown Alga Dictyopteris divaricata
Two new brominated selinane sesquiterpenes, 1-bromoselin-4(14),11-diene (1) and 9-bromoselin-4(14),11-diene (2), one known cadinane sesquiterpene, cadalene (3), and four known selinane sesquiterpenes, alpha-selinene (4), beta-selinene (5), beta-dictyopterol (6), and cyperusol C (7), were isolated from a sample of marine brown alga Dictyopteris divaricata collected off the coast of Yantai (China...
متن کاملA new cadinane sesquiterpene from the marine brown alga Dictyopteris divaricata.
A sample of the marine brown alga D. divaricata collected off the coast of Yantai (P.R. China) was dried, powdered, and extracted with the mixture of CHCl(3) and MeOH (1:1, v/v). By a combination of silica gel and Sephadex LH-20 column chromatography and preparative TLC, a new cadinane sesquiterpene 1,4-epoxymuurolan-5beta-ol (1) was isolated from this species. Its structure was established by ...
متن کاملA New Epoxy-cadinane Sesquiterpene from the Marine Brown Alga Dictyopteris divaricata
A new epoxy-cadinane sesquiterpene, 4beta,5beta-epoxycadinan-1beta-ol (1), and six known cadinane sesquiterpenes: cadinan-1,4,5-triol (2), 4alpha,5beta-dihydroxycubenol (3), cubenol (4), cadinan-3-ene-1,5-diol (5), cubenol-3-one (6), and torreyol (7), were isolated from a sample of marine brown alga Dictyopteris divaricata collected off the coast of Yantai (China). Their structures were establi...
متن کاملLipid and Fatty Acid Composition of the Marine Brown Alga Dictyopteris membranacea
Glycerolipids and fatty acids of D. membranacea (Dictyotales) were analysed. The betaine lipid DGTA and the glycolipids MGOG, DGDG and SQDG were major components. The phospholipids PE, PG, PI and PHEG were present in minor amounts only. This lipid pattern, which is characterised by the presence of DGTA and the absence of PC, has been found exclusively in brown algae belonging to the orders Dict...
متن کاملDiterpenes from the Brown Alga Dictyota crenulata.
The crude extract of the Brazilian brown alga Dictyota crenulata was analyzed by NMR spectroscopy and HRGC-MS techniques. Seven diterpenes were identified: pachydictyol A, dictyodial, 4beta-hydroxydictyodial A, 4beta-acetoxydictyodial A, isopachydictyol A, dictyol C and dictyotadiol. Xeniane diterpenes have previously been found in D. crenulata from the Pacific Ocean. The results characterize D...
