Variation in quantitative and qualitative alkaloid composition in Phalaris arundinacea (Poaceae)
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 2
Abstract
Research of the identification and determination of alkaloid contents in the aboveground parts of Phalaris arundinacea (Poaceae) during various periods of the vegetation season was conducted. Analyses were performed using an apparatus system by Hewlett-Packard (USA), consisting of a gas chromatograph model 589011 and a mass detector model 5971 A. Analyses were conducted at the laboratory of the phytochemistry at the Institute of Bioorganic Chemistry, PAS in Poznań. A total of six alkaloids were identified in the analysed material, i.e. tryptophol and gramine (indole alkaloids) as well as lupanine and 13-OH lupanine and lupanine esters – 13 a-isovalericlupanine and 13 a-tigloyloxylupanine (quinolysidine alkaloids). Gramine and lupanine are the dominant alkaloids in the growth stage.
