Alkaloid patterns in Leucojum aestivum shoot culture cultivated at temporary immersion conditions
چکیده انگلیسی

The alkaloid patterns in Leucojum aestivum L. shoot culture cultivated at temporary immersion conditions were investigated using gas chromatography–mass spectrometry. 18 alkaloids were identified, and galanthamine, hamayne and lycorine were dominant. The L. aestivum 80 shoot culture, cultivated at temporary immersion conditions, is a prospective biological matrix for obtaining wide range Amaryllidaceae alkaloids, showing valuable biological and pharmacological activities. The temperature of cultivation influenced enzyme activities, catalyzing phenol oxidative coupling of 4′-O-methylnorbelladine and formation of the different groups Amaryllidaceae alkaloids. Decreasing the temperature of cultivation of L. aestivum 80 shoot culture led to activation of para-ortho’ phenol oxidative coupling (formation of galanthamine type alkaloids) and inhibited ortho-para’ and para-para’ phenol oxidative coupling (formation of lycorine and haemanthamine types alkaloids).
