Cucurbitacins from Bacopa monnieri☆

Phytochemistry, 2007
Four cucurbitacins, bacobitacin A-D (1-4) as well as, a known cytotoxic, cucurbitacin E (5) together with three known phenylethanoid glycosides, monnieraside I, III and plantioside B were isolated form the aerial part of Bacopa monnieri. Their structures were elucidated on the basis of extensive spectroscopic investigations (1D, 2D NMR and ESI-QTOF-MS ...

Cucurbitacins

Journal of Chemical Ecology, 1985
Four species of diabroticites with different host specificities are shown for the first time to sequester cucurbitacins. While all beetles fed on an artificial diet (no cucurbitacins) were readily consumed by Chinese praying mantids, a significant proportion of adultDiabrotica balteata (72%),D. undecimpunctata howardi (46%), andD.

Cucurbitacins From Bryonia Verrucosa. Isomerization of 2-Hydroxy-3-Keto-Cucurbitacins

Natural Product Research, 1999
Abstract Three new cucurbitacins as well as thirteen known ones were isolated from the fruits of Bryonia verrucosa. the new compounds were characterized by chemical and spectral methods. an effective and simple method to isomerize 2-hydroxy-3-keto-cucurbitacins in acid media is described.

A new cucurbitacin profile forCucurbita andreana: A candidate for cucurbitacin tissue culture

Journal of Chemical Ecology, 1993
In addition to previously reported cucurbitacins B,1, and D,2, cucurbitacin E,3, and I,4, aglycones and their glucosides 2-O-β-glucopyranosyl-cucurbitacin E,5, and 2-O-β-glucopyranosyl-cucurbitacin I,6, were isolated and identified as constituents ofCucurbita andreana on the basis of MS, FD-MS, 1 H NMR and(13)C NMR spectroscopy.
