Steroidal glycoalkaloids in Solanum chacoense.
Potato (Solanum tuberosum L.), a domesticated species that is the fourth most important world agricultural commodity, requires significant management to minimize the effects of herbivore and pathogen damage on crop yield. A wild relative, Solanum chacoense Bitt., has been of interest to plant breeders because it produces an abundance of novel steroidal glycoalkaloid compounds, leptines and lept...
متن کاملIsolation of steroidal glycoalkaloids from Solanum incanum by two countercurrent chromatographic methods.
Using a bioassay for inhibition of plant growth and a combination of two countercurrent chromatographies: rotation locular countercurrent chromatography and droplet countercurrent chromatography, two biologically active glycosidal alkaloids, solasonine and solamargine were isolated from fresh ripe fruit of Solanum incanum. The combination of these chromatographic techniques has established an e...
متن کاملSteroidal Glycoalkaloids and Molluscicidal Activity of Solanum asperum Rich. Fruits
Solanum L. (Solanaceae) is distributed mainly throughout the tropical and subtropical regions of the world and is the largest and most complex genus of the family Solanaceae. In Brazil, Solanum is represented by about 350 species. In this region, many species of Solanum are widely used in popular medicine and are commonly known as ‘yubeba’, the word derived from Tupi Guarani that refers to the ...
متن کاملEffects of steroidal glycoalkaloids from potatoes (Solanum tuberosum) on in vitro bovine embryo development.
alpha-Solanine and alpha-chaconine are two naturally occurring steroidal glycoalkaloids in potatoes (Solanum tuberosum), and solanidine-N-oxide is a corresponding steroidal aglycone. The objective of this research was to screen potential cyto-toxicity of these potato glycoalkaloids using bovine oocyte maturation, in vitro fertilization techniques and subsequent embryonic development as the in v...
متن کاملSterol side chain reductase 2 is a key enzyme in the biosynthesis of cholesterol, the common precursor of toxic steroidal glycoalkaloids in potato.
Potatoes (Solanum tuberosum) contain α-solanine and α-chaconine, two well-known toxic steroidal glycoalkaloids (SGAs). Sprouts and green tubers accumulate especially high levels of SGAs. Although SGAs were proposed to be biosynthesized from cholesterol, the biosynthetic pathway for plant cholesterol is poorly understood. Here, we identify sterol side chain reductase 2 (SSR2) from potato as a ke...
