Additional new minor cucurbitane glycosides from Siraitia grosvenorii.
Continuous phytochemical studies of the crude extract of Luo Han Guo (Siraitia grosvenorii) furnished three additional new cucurbitane triterpene glycosides, namely 11-deoxymogroside V, 11-deoxyisomogroside V, and 11-deoxymogroside VI. The structures of all the isolated compounds were characterized on the basis of extensive NMR and mass spectral data as well as hydrolysis studies. The complete ...

From the fruits of Trichosanthes tricuspidata, 14 cucurbitane glycosides (khekadaengosides A-J, M-N, cucurbitacin J 2-O-beta-glucopyranoside and cucurbitacin K 2-O-beta-glucopyranoside), a hexanorcucurbitane glucoside (khekadaengoside K) and octanorcucurbitane (khekadaengoside L) were isolated along with two known cucurbitane glucosides (cucurbitacin 2-O-beta-glucopyranoside and 25-O-acetyl-cuc...
متن کاملUnripe red fruits may be aposematic.
The unripe fruits of certain species are red. Some of these species disperse their seeds by wind (Nerium oleander, Anabasis articulata), others by adhering to animals with their spines (Emex spinosa) or prickles (Hedysarum spinosissimum). Certainly neither type uses red coloration as advertisement to attract the seed dispersing agents. Fleshy-fruited species (Rhamnus alaternus, Rubus sanguineus...

متن کاملNew Glycosides from the Fruits of Nicandra physaloides.
Three new glycosides (1-3) and 15 known ones (4-18) were isolated and identified from the fruits of Nicandra physaloides. The structures of these compounds were established by 1D and 2D NMR spectra and HR-ESI-MS. The compounds (4-18) were the first time isolated from the Nicandra genus and they (except 8, 10, 14) exhibited inhibitions on the NO release of LPS-induced RAW 264.7 cells with IC50 v...
