The antifeedant effect of six cacalolides and six eremophilanolides was tested against the herbivorous insects Spodoptera littoralis, Leptinotarsa decemlineata, and Myzus persicae. The test compounds included several natural products isolated from Senecio madagascariensis (14-isovaleryloxy-1,2-dehydrocacalol methyl ether, 4), S. barba-johannis (13-hydroxy-14-oxocacalohastine, 5; 13-acetyloxy-14...

Due to depleting water supplies and the cultivation of high water-demanding crops such as lucerne, effect deficits in crop production has become a major concern, especially semiarid regions China. A six-year field experiment (2012–2018) was conducted evaluate soil recovery fertility after lucerne-to-crop conversions on western Loess Plateau Six rotation treatments (lucerne initially grew from 2...

Oleic acid (18:1) is hydroxylated exclusively on the terminal methyl by a microsomal cytochrome P-450-dependent system ([omega]-OAH) from clofibrate-induced Vicia sativa L. (var minor) seedlings (F. Pinot, J.-P. Salaun, H. Bosch, A. Lesot, C. Mioskowski, F. Durst [1992] Biochem Biophys Res Commun 184: 183-193). This reaction was inactivated by two terminal acetylenes: (Z)-9-octadecen-17-ynoic a...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...

Dietary polyphenols, including anthocyanins, are suggested to be involved in the protective effects of fruits and vegetables against cancer. However, anticancer effects of peonidin 3-glucoside have not been clearly demonstrated, with only limited studies being available concerning the inhibitory effect of cyanidin 3-glucoside for tumor cell growth. Therefore, in this study, we have isolated and...

The present study was designed to investigate the possible insulinotropic properties of Nigella sativa L. (N. sativa) oil in Streptozotocin plus Nicotinamide-induced diabetes mellitus in hamsters. Nicotinamide was injected intraperitoneally 15min before injection of Streptozotocin intravenously. Oral treatment with N. sativa oil began 4 weeks after induction of diabetes. Serum insulin was measu...
