Several dietary and medicinal herbs have been shown to be effective in the treatment prevention of cancer. Although Piper nigrum has anti-cancer activities against various cancer cells, its anti-pancreatic properties not reported. In present study, P. extract (PNE) inhibited proliferation PANC-1 human pancreatic cells. Flow cytometry showed G0/G1 arrest caused by PNE addition, Western blot anal...

Solanum genotypes that differ in the level of polygenic resistance to the oomycete plant pathogen Phytophthora infestans were studied for their oxidative response to culture filtrate (CF) of the pathogen. Reactive oxygen species (ROS) production, peroxidase activity and lipid peroxidation have been studied in the CF-treated cell suspensions derived from leaves of the resistant S. nigrum (nonhos...

Twelve steroidal alkaloids were isolated from four populations of Veratrum lobelianum Bernh. and Veratrum nigrum L. Full NMR data for veralosinine (1), and extensive 1H NMR data for veralosine (3) and teinemine (5) are presented here for the first time. (+/-)-15-O-(2-Methylbutyroyl)germine (10) is undescribed up to now. The antiproliferative activities of veranigrine, veralosinine, and neogermi...

Eggplant is the fifth most economically important solanaceous crop after potato, tomato, pepper, and tobacco. Apart from the well-known brinjal eggplant (Solanum melongena L.), two other under-utilized eggplant species, the scarlet eggplant (S. aethiopicum L.) and the gboma eggplant (S. macrocarpon L.) are also cultivated. The taxonomy and identification of eggplant wild relatives is challengin...

As argued above, more-durable mulch species are desirable; but mixtures are feasible and might include a proportion of readily-decomposable foliage species such as Gliricidia sepium , which is very well-known throughout Central and South America . The research project reported here has trials of pepper ( Piper nigrum ) grown on living supports of this species, between hedgerows of Inga . The pe...
