The mass extraction of potato glycoalkaloids from blossoms

Comparative composition of aerial and subterranean potato tubers (Solanum tuberosum L)

“…Presently puriÐed secondary metabolites such as glycoalkaloids used for toxicological and pharmaceutical purposes are extracted from Ñowers (Bushway et al 1980) which contain higher concentrations than those in the aerial tissue reported here (Jadhav et al 1981). Although, wild Solanum spp contain higher glycoalkaloid concentrations than those in aerial tubers reported here (Gregory 1981), wild Solanum spp also contain a diverse array of glycoalkaloids (leptines, commersonine) and individual compounds associated with undesirable potato Ñavours, mammalian toxicity and teratogenicity as well as, or instead of, a-solanine and a-chaconine.…”

Extraction and determination of the potato glycoalkaloidα-solanine in soil

“…For use in the method development, -solanine was extracted and isolated from potato sprouts by the method of Bushway et al [23]. Isolation and purification of -solanine were done according to Bushway [24].…”

“…Using an aqueous solution of 5% acetic acid, a reagent which had previously been used for extraction of -solanine from potato tubers [25], no -solanine was extracted. Using a solution of THF : water : ACN (50 : 30 : 20), a reagent which had previously been used for extraction of -solanine from freeze-dried potato blossoms [23], a recovery of 34% was obtained. A similar solution with an addition of acetic acid (50 : 30 : 20 : 1) was previously used by Bushway et al [26] for extraction from freeze-dried or dehydrated potatoes.…”

Steroidal Glycoalkaloids: Isolation, Structure, Analysis, and Biosynthesis

“…To provide sufficient material for these synthetic conversions, large-scale extractions are required. Bushway et al [55] have proposed a method that could be applied to largescale extraction of SGAs. In this method, freeze-dried potato blossoms are blended in a mixture of tetrahydrofuran, water and acetonitrile (5:3:2).…”
