“…The literature describes over 20 different types of the solvents used for the glycoalkaloids extraction, for example, ethanol [7], 5% acetic acid [8], methanol-acetic acid-water (94:1:6) [9], methanol-chloroform (2:1) [10], etc.…”

“…The glycoalkaloids were isolated from lyophilized callus tissue by ethanolic extraction and ammoniacal precipitation by a procedure similar to Dabbs and Hilton (6 Figure 1 shows the effect of increasing the period of incubation on the weight of explant plus callus. Even when glucose was substituted for sucrose the growth profiles were similar.…”

Callus was initiated from explants of tubers of the Norchip cultivar of Solanum tuberosum L. and grown on medium with a single carbon source and without addition of coconut milk, protein hydrolysate, or amino acid. Callus samples were harvested at intervals and compared to mature tubers for which there was good biochemical knowledge.The amino acid spectrum, the glycoalkaloid content, and the properties of the isolated invertase and sucrose synthetase were similar in callus and in tuber. Significantly the level of sucrose synthetase varied with the age of the developing callus just as it did with the age of the developing tuber. Of greater significance, levels of reducing sugars and invertase varied with the age of developing caOlus and also with time and temperature of storage after the callus has ceased growth. Similar changes occur in intact tubers.Callus and tuber biochemistry differed in the amount of deposited starch and in the absence of potato invertase inhibitor.Data correlation in the study of carbohydrate transformation in developing potato tubers from 1 year to the next becomes increasingly difficult due to the uncontrolled variables of temperature, moisture, sunlight, and the short 4-to 6-week period of desired sampling.

“…The tuber glycoalkaloid (TGA) content of potato tubers is normally 2-10 mg/ 100 g fresh weight, although levels as high as 58 mg/l00 g have been reported (Salunkhe & Salunkhe 1974). High TGA concentrations are often associated with green potatoes, but the two processes are independent, and toxic TGA levels may occur in the absence of chlorophyll formation (Dabbs & Hilton 1953) .…”

Tuber glycoalkaloids {TGA) in seven New Zealand potato culti vars were assessed before and after a period of exposure to light. Differences between cultivars were marked, TG.A. concentration ranging from 2.5 to 47.5 mg/100 g fresh weight, Ranking of cultivars was similar before and after exposure. Immature tubers had a higher initial TGA content than mature tubers and accumulated more TGA over the period of exposure. In 'Ham Hardy' tubers, TGA increased most rapidly during the first 20 days. TGA from potato tuber extracts contained three components, one of which was identified as solanine.
