MOLLUSCICIDAL SAPONINS FROM SWARTZIA SIMPLEX
Borel, Christian,Gupta, Mahabir P.,Hostettmann, Kurt
, p. 2685 - 2690 (1987)
One monodesmosidic saponin and six bidesmosidic saponins have been isolated from the methanolic extract of the leaves of Swartzia simplex.They were shown to be glucuronides of oleanolic acid, gypsogenin and gypsogenic acid by chemical and spectral means.The monodesmosidic saponins exhibit various molluscicidal activities against the schistosomiasis-transmitting snail Biomphalaria glabrata. - Key Word Index: Swartzia simplex; Leguminosae; triterpene saponins; schistosomiasis; molluscicidal activity.
Triterpenoid glycosides from the fruits of Kochia scoparia
Wen,Chen,Cui,Li,Wang
, p. 450 - 452 (1995)
From the fruits of Kochia scoparia (L.) Schrad, five triterpenoid glycosides were isolated for the first time from this plant. They were elucidated as momordin 1c, the 6'-methyl ester of momordin 1c, momordin IIc, 2'-O-β-D-glucopyranosylmomordin Ic, and 2'-O-β-D-glucopyranosylmomordin IIc on the basis of spectral and chemical methods. The last two saponins are new natural products.

Ten minor saponins, momordins Ia-Ie and IIa-IIe, were isolated from the root of Momordica cochinchinensis, along with the known major saponins, momordins I and II.Their structures were established on the basis of chemical and spectroscopic analysis.The structures of the two new saponins were assigned as 3β-(((O-β-D-xylopyranosyl-(1-->2)-O-β-D-xylopyranosyl-(1-->3))O-β-D-glucopyranuronosyl)oxy)-olean-12-ene-28-oic acid for momordin Id and momordin Id-28-β-D-glucopyranosyl ester for momordin IId.It was confirmed that the genuine saponin present in the root was not the monodesmoside but the bisdesmoside, though the former is the major component in the dry root.

Four new triterpenoid saponins named kalopanax-saponins C (4), D (5), E (6) and F (7) were isolated from the roots of Kalopanax septemlobus (THUNB.) KOIDZ. together with three known saponins, kalopanax-saponins A (1) and B (2), and chikusetsusaponin IV (3).On the basis of chemical and spectral data, the structures of these new saponins were elucidated to be as follows: (4), 3-O-α-rhamnopyranosyl-(1->2)-3)>-α-arabinopyranosyl hederagenin 28-O-α-rhamnopyranosyl-(1->4)-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; (5), 3-O-α-rhamnopyranosyl-(1->2)-3)>-α-arabinopyranosyl oleanolic acid 28-O-α-rhamnopyranosyl-(1->4)-β-glucopyranosyl-(1->6)-β-glucopyranosyl ester; (6), 3-O-β-glucopyranosyl-(1->3)-β-glucuronopyranosyl oleanolic acid; (7), 3-O-α-arabinopyranosyl-(1->2)-3)>-β-glucuronopyranosyl oleanolic acid 28-O-β-glucopyranosyl ester.Keywords - Kalopanax septemlobus; Araliaceae; saponin; kalopanax-saponin; oleanolic acid glycoside; hederagenin glycoside; Chinese folk medicine; ciqiu
Structure of Two New Saponins from Achyranthes aspera
Seshadri, V.,Batta, A. K.,Rangaswami, S.
, p. 773 - 775 (2007/10/02)
From the unripe fruits of Achyranthes aspera two new saponins (C and D) have been isolated and their structures elucidated.Saponin-C has been shown to be β-D-glucopyranosyl ester of α-L-rhamnopyranosyl(1->4)-β-D-glucuronopyranosyl(1->3)oleanoic acid (I) and saponin-D as β-D-glucopyranosyl ester of α-L-rhamnopyranosyl(1->4)-β-D-glucopyranosyl(1->4)-β-D-glucuronopyranosyl(1->3)oleanoic acid (IV).
