cephalaria microcephala/glycoside

A new lignan glycoside, 1,5-dihydroxy-2-(4"-beta-D-glucopyranosyloxy-3"-methoxyphenyl)-6-(4'-hydroxy-3'-methoxyphenyl)-3,7-dioxabicyclo[3.3.0]octane, named ambrosidine ([structure: see text]), along with seven known compounds (four iridoids and three hydroxycinnamic esters) were isolated from the

Two novel triterpene glycosides, paphlagonoside A (1) and B (2), were characterised as 28-O-[beta-D-glucopyranosyl(1 --> 2)-alpha-L-arabinopyranosyl(1 --> 4)-beta-D-glucopyranosyl]-hederagenin (1) and 28-O-[beta-D-xylopyranosyl(1 --> 4)-alpha-L-rhamnopyranosyl(1 --> 3)-beta-D-xylopyranosyl (1 -->

A phytochemical investigation of the aerial parts of Cephalaria elmaliensis resulted in the isolation of ten hederagenin-type triterpene saponins (1-10) including three new ones, elmalienoside A (1), elmalienoside B (2), elmalienoside C (3), and two known flavonoid glycosides (11-12). Their

Transsylvanoside B, which is a new acidic triterpene glycoside, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined as 3-O-[beta-D- glucopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyran osy l (1-->4)-beta-D-xylopyranosyl]-3 beta,23-dihydroxy

A new acidic triterpene glycoside, transsylvanoside A, was isolated from dried flowers of Cephalaria transsylvanica. The structure was determined to be 3-O-[beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1-->4)-al pha-L-rhamnopyranosyl(1-->4)-beta-D-xylopyranosyl]-3beta,23-dihydroxy

On the basis of spectroscopic and chemical methods, the structures of two new triterpenoid glycosides, transsylvanoside E and F, isolated from Cephalaria transsylvanica have been established as 3-O-[beta-D-xylopyranosyl (1-->3)-alpha-L-rhamnopyranosyl (1-->4)-beta-D-glucopyranosyl

Five new oleanane-type triterpenoid glycosides (1-5), named scoposides A-E, along with one known bisdesmosidic triterpene glycoside, were isolated from the aerial parts of Cephalaria scoparia. Three prosapogenins (2a-4a) were also obtained after alkaline hydrolysis of the bisdesmosidic compounds

Three new triterpenoidal saponins, 3-O-[beta-D-glucopyranosyl(1-->4)-beta-D-Glucopyranosyl(1-->3)-alpha-L- rhamnopyranosyl (1-->4)-beta-D-xylopyranosyl]-hederagenin 28-O-[beta-D-glucopyranosyl (1-->4)-beta-D-glucopyranosyl] ester (1), 3-O-[beta-D-glucopyranosyl

A new hederagenin-type triterpenoid glycoside (1) named Aytachoside A, along with eight known triterpene glycosides, were isolated from the aerial parts of Cephalaria aytachii Gokturk and Sumbul (Dipsacaceae). The structures of compounds 1-9 were determined by spectroscopic (1D and 2D NMR, HRESIMS)

Crude acetone and ethanol extracts of the aerial parts of 21 Cephalaria species collected from Turkey were investigated for larvicidal and adult topical activity against Aedes aegypti. The ethanol extracts from C. elazigensis var. purpurea, C. anatolica, and C. elmaliensis possessed the highest
