Triterpenes and triterpene glycosides from Paradrymonia macrophylla

Phytochemistry, 1996
Abstract Seven pentacyclic triterpenes and triterpene glycosides have been isolated from the stems and roots of Paradrymonia macrophylla and their structures elucidated by means of 1H and 13C NMR spectroscopy. Three of them are described for the first time as natural products, namely: 2α,3β,19α-trihydroxy-24-oxo-urs-12-en-28-oic acid (24-epi ...

Radioimniunoassay of Aescine, a Mixture of Triterpene Glycosides

Journal of Immunoassay, 1990
A radioimmunoassay (RIA) has been developed for the determination of picogram amounts of aescine, an anti-inflammatory and anti-oedematous glycoside mixture from unpurified extracts of Aesculus hippocastanum. Practically no interference is observed for various potentially crossreacting compounds.

Triterpene glycosides from Schefflera octophylla

Phytochemistry, 1991
In addition to 3-epi-betulinic acid, three triterpene glycosides were isolated from leaves of Schefflera octophylla. The structures of the glycosides have been determined as 28-O-[alpha-L-rhamnopyranosyl(1----4)-O-beta-D-glucopyranosyl(1----6)-be ta-D- glucopyranosides of 3 alpha-hydroxy-lup-20(29)-ene-23,28-dioic acid, 3 alpha,11 alpha- dihydroxy ...

Triterpenes and triterpene glycosides from the leaves of Ilex rotunda

Phytochemistry, 1993
Abstract Two new triterpenes, ilexolic acid A and B, and seven new saponins, ilexosides XXXIII–XXXIX, together with the known saponin rotungenoside were isolated from the fresh leaves of Ilex rotunda , and their structures elucidated on the basis of chemical and physicochemical evidence.

Triterpene glycosides of Caltha silvestris

Chemistry of Natural Compounds, 1972
It has been established that calthoside D is hederagenin 3-[O-β-D-glucopyranosyl-(1→2)-α-L-arabopyranoside] and is identical with caulosaponin B.

Triterpene glycosides ofGypsophilla trichotoma

Chemistry of Natural Compounds, 1970
The plantGypsophilla trichotoma Wend. has been found to contain four triterpene glycosides, which have been called “trichosides” A, B, C, and D. Trichoside D has been isolated in the individual state. It has been shown that its aglycone is gypsogenin. The carbohydrate chain attached to the hydroxyl at C3 contains D-galactose, L-arabinose, D-xylose, and

Triterpene glycosides fromSaponaria officinalis

Chemistry of Natural Compounds, 1969
The roots ofSaponaria officinalis L. have yielded the known triterpene glycoside gypsoside and the first glycoside of gypsogenic acid, which has been named saponaroside. Saponaroside is the 3-β-D-xylopyranoside of gypsogenic acid.
