Gibsmithia hawaiiensis gen. n. et sp. n.J
ABSTR ACT : A new genus , Gibsmithia, is described and tentatively placed in the Dumontiaceae of the red algal order Cryptonemiales. Its diagnostic features are: possession of auxiliary cells in specialized filaments separate from those bearing the carpogonia; the known sexual structures occurring in sori at the tips of soft, gelatinous branches which arise from perennial round stems so as to f...
متن کاملRhizobium calliandrae sp. nov., Rhizobium mayense sp. nov. and Rhizobium jaguaris sp. nov., rhizobial species nodulating the medicinal legume Calliandra grandiflora.
Calliandra grandiflora has been used as a medicinal plant for thousands of years in Mexico. Rhizobial strains were obtained from root nodules of C. grandiflora collected from different geographical regions in Chiapas and characterized by BOX-PCR, amplified rDNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis. Most isolates corresponded to members of the genus Rhizobium and thos...

From the leaves of Cryptostegia grandiflora, four new cardiac glycosides oleandrigenin 3-O-beta-glucopyranosyl-(1-->4)-beta-cymaropyranosyl-(1-->4)-beta-digitoxopyranoside, cryptostigmin I, oleandrigenin 3-O-beta-glucopyranosyl-(1-->4)-alpha-rhamnopyranoside, cryptostigmin II, 16-propionylgitoxigenin 3-O-beta-glucopyranosyl-(1-->4)-alpha-rhamnopyranoside, cryptostigmin III and oleandrigenin 3-O...
متن کاملChemical Constituents of Ajuga parviflora
Two new antifungal withanolides, (1) and (2) have been isolated from the defatted methanolic extract of Ajuga parviflora. Their structures were established as 3/3,17/3,20-trihydroxyl-oxo-(20/?, 22/?)-witha-5,14,24-trienolide (1), 28-hydroxy-14,20-epoxy-l-oxo-(22/?)-witha2,5,24-trienolide (2) on the basis of spectroscopic data including two dimensional NMR tech niques. The pyrrolizidine alkaloi...
متن کاملCryptostegia grandiflora — a potential multi - use crop
Cryptostegia grandiflora, a member of Asclepiadaceae, was evaluated as a potential multi-use crop. The plant contained 14.0% protein, 6.5% oil, 6.9% polyphenol, and 2.13% hydrocarbon. The gross heat value of the species was 3878.0 cal/g, while the oil fraction was 7350.1 cal/g, and the hydrocarbon fraction was 9300.0 cal/g. The NMR spectra of the hydrocarbon fraction reveals the presence of cis...
