Biological Activity of Crude Extract and Saponin Pseudoginsenoside-RT1 Derived from the Fruit of Randia siamensis[Reference:
WebLink]
METHODS AND RESULTS:
Ursolic acid (1), pseudoginsenoside-RP 1 (2), and Pseudoginsenoside RT1 (3) were isolated from the fruit of Randia siamensis. 13 C NMR spectroscopy was particularly useful in confirming the structures of these components. Studies with rats showed that saponin 3 caused a decrease in blood pressure, an increase in heart rate and an increase in spontaneous contractility of the uterus.
CONCLUSIONS:
Also, a crude ethanol extract of the fruit of R. siamensis exhibited acute ichthyotoxic activity.

Oleanolic acid saponins from root bark of Aralia elata.[Pubmed:
7764823]
Three new oleanolic acid glycosides, tarasaponins I-III, were isolated as their methyl esters from the root bark of Aralia elata together with four known glycosides, the methyl esters of chikusetsusaponins IVa, IV, 28-desglucosyl-chikusetsusaponin IV and Pseudoginsenoside RT1.
METHODS AND RESULTS:
Tarasaponins I-III were characterized as oleanolic acid 3-O-[beta-D-glucopyranosyl(1-->3)][alpha-L-arabinofuranosyl(1-->4)[- beta-D-glucuronopyranoside, oleanolic acid 3-O-[beta-D-xylopyranosyl(1-->2)][beta-D-galactopyranosyl(1-->3)]-beta- D-glucuronopyranoside and beta-D-glucopyranosyl oleanolate 3-O-beta-D-galactopyranosyl(1-->3)-beta-D-glucuronopyranoside, respectively.
