New Hopane Triterpene from Eleocharis sellowiana (Cyperaceae)
The genus Eleocharis R. Br. (Cyperaceae, Cyperoideae, Scirpeae) includes about 200 species, occurring in wet environments like swamps, lakes and rivers margins. Their aerial parts are formed by simple, not ramified stalks that end in a spiciform inflorescence formed by numerous very inconspicuous flowers. Their subterraneous parts are formed by roots and stem (called rhizome or stolon, dependin...
متن کاملChromosome reduction in Eleocharis maculosa (Cyperaceae).
Chromosome numbers in Cyperaceae lower than the typical basic number x = 5 have been described for only three species: Rhynchospora tenuis (n = 2), Fimbristylis umbellaris (n = 3) and Eleocharis subarticulata (n = 3). Eleocharis maculosa is recorded here as the fourth species of Cyperaceae that has a chromosome number lower than 2n = 10, with 2n = 8, 7 and 6. The karyotype differentiation in E....
متن کاملConstituents of a fern, Diplazium subsinuatum. III. Four new hopane-triterpene lactone glycosides.
From a whole plant of a fern, Diplazium subsinuatum, three new hopane-triterpene lactone glycosides, diplaziosides V-VII (1-3), were isolated, together with a new monoacetyl derivative (4) of diplazioside VII (3). Compounds 1-3 were defined as the respective 3-O-[beta-D-glucopyranosyl-(1-->2)]-beta-D-glucopyranosides of 3beta,24-dihydroxyhopan-28,22-olide (1), of 3beta,17,24-trihydroxyhopan-28,...
متن کاملA New Lanostane Triterpene from Skimmia laureola
Skimmia laureola Hook (Rutaceae) is found in Kashmir and in the mountains of Northern Pakistan and is used in folklore medicine for the treatment of various ailments [1 – 3]. The quinoline alkaloids of this plant have demonstrated antifungal and immunomodulating properties [4, 5]. The ethanolic extracts of the aerial parts of S. laureola are active against the animal pathogen Microsporium canis...
متن کاملFour new triterpene glycosides from Thalictrum squarrosum.
Four new triterpene glycosides were isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). They were designated as squarroside I, being a cycloartane-type glycoside, and squarrosides II, III and IV, being oleanene-type glycosides. Their structures were established by using two dimensional (2D) NMR techniques.
