Methods of analysis for solanine in tubers of solanum tuberosum /

“…It is of interest to note that Rooke and his co-workers (24) have stated that ninety minutes is -required for maximum color density to be reached, which contrasts sharply with the find¬ ings in the present work. After several tests, all of which conformed to the curve shown in Figure 2, xo { rx/ nXvX-ii: v ::■:…”

“…Rooke, et al, (24) said that the method of extraction of Bomer and Mattis, and also the modification of Conner, which necessitated the use of a large quantity of raw material, were found to give a sticky, semi-colloidal precipitate of solanine, difficult to filter and purify.…”

Role of Carbohydrate Side Chains of Potato Glycoalkaloids in Developmental Toxicity

“…The FETAX solution (including all controls) used for that experiment was also adjusted to pH 6.9, which is within limits set by the ASTM (1991). We have previously showed that -chaconine and -solanine are soluble 0021-8561/94/1442-1511$04 in FETAX solution at these concentrations (Friedman et al, 1991;Rooke et al, 1943). Additional studies using HPLC to measure concentrations in solutions confirmed the solubilities of the hydrolysis products at the concentrations used.…”

Effects on the Alkaloid Content of Potatoes Grown From Seeds Subjected to Low‐dose Gamma Irradiation

“…Intensive investigation during World War II led to a modification of Pfankuch's (1937) analytical method (Rooke et al, 1943). Dabbs and Hilton (1953) developed a shorter method for extraction and analytical determination of solanine.…”
