Isolation and identification of oviposition deterrents to cabbage butterfly,Pieris rapae, fromErysimum cheiranthoides.

Journal of chemical ecology

Sachdev-Gupta K, Renwick JA, Radke CD.

J Chem Ecol. 1990 Apr;16(4):1059-67. doi: 10.1007/BF01021010.

Avoidance of some crucifer species by the crucifer specialist,Pieris rapae, has been attributed to the presence of oviposition deterrents in these plants. Studies on one such unacceptable plant,Erysimum cheiranthoides, have resulted in the isolation ofn-butanol-soluble deterrents from the alcoholic...

Two new cardiac glycosides were isolated from the seeds of Erysimum cheiranthoides. Their structures were characterized as strophanthidin glycosides of 3-O-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl and 3-O-beta-D-glucpyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->4)-3-O-acetyl-beta-D-digitoxopyranosyl.

Role of Intracellular Sodium Activity in the Control of Contraction in Cardiac Purkinje Fibers.

PMID: 11725004
J Biomed Sci. 1994 Dec;1(1):28-42. doi: 10.1007/BF02258337.

The role of intracellular sodium activity (a(i)(Na)) in the control of force was studied in sheep cardiac Purkinje fibers exposed to norepinephrine (NE) and high [Ca](o) in the absence and presence of overdrive or of a low concentration of...

Cesium, Na(+)-K(+) Pump and Pacemaker Potential in Cardiac Purkinje Fibers.

Journal of biomedical science

Sternlicht JP, Vassalle M.
PMID: 11725074
J Biomed Sci. 1995 Oct;2(4):366-378. doi: 10.1007/BF02255224.

The mechanisms of the hyperpolarizing and depolarizing actions of cesium were studied in cardiac Purkinje fibers perfused in vitro by means of a microelectrode technique under conditions that modify either the Na(+)-K(+) pump activity or I(f). Cs(+) (2 mM)...

Oviposition responses ofPieris rapae andP. napi oleracea to 18 cardenolides were compared under the same conditions. Effects of different concentrations of selected cardenolides were also tested. Most of the compounds were deterrent to oviposition by both insects, but to...

From the leaves of Convallaria majalis L. eight glycosides of strophanthidin, cannogenol, sarmentogenin and 19-hydroxysarmentogenin, resp., were isolated and structurally elucidated as strophanthidin-3-O-6'-deoxy-beta-D-allosido-alpha-L-rhamnoside, strophanthidin-3-O-6'-deoxy-beta-D-allosido-alpha-L-arabinoside, strophanthidin-3-O-alpha-L-rhamnosido-2'-beta-D-glucoside, cannogenol-3-O-6'-deoxy-beta-D-allosido-beta-D-glucoside, cannogenol-3-O-6'-deoxy-beta-D-allosido-alpha-L-rhamnoside, 19-hydroxy-sarmentogenin-3-O-alpha-L-rhamnoside, sarmentogenin-3-O-6'-deoxy-beta-D-allosido-alpha-L-rhamnoside and sarmentogenin-3-O-6'-deoxy-beta-D-guloside, mainly by means of their H-NMR-spectra, by EI-MS...
