説明

During the course of our studies on physiologically active substances in citrus fruit peels, two nitrogenous compounds and four alkyl glycosides were isolated from lemon, unshiu, hassaku, yuzu and iyokan peels. Their structures were determined by MS, 1H-NMR and 13C-NMR spectroscopy, and chemical evidence. Isolated were: N, α', N', α-cyclo di (4-methylaminobenzeneethanol) [1], adenosine [2], ethyl-1-O-β-glucopyranoside [3], propyl-1-O-β-glucopyranoside [4], hexyl-1-O-β glucopyranoside [5] and hexyl-1-O-(6-O-apiosyl-β-glucopyranoside) [6]. Each compounds [2] and [3] were found to lower blood pressure, but compounds [1], [5] and [6] raised blood pressure. Among these compounds, [1] is a new compound, whereas [2]_??_[6] were identified in citrus fruit peels for the first time.
