Chemical Constituents of Cordyceps cicadae
Abstract:
One new bifuran derivative (1), together with fourteen known compounds, were isolated from Cordyceps cicadae X. Q. Shing. The known compounds included nine nucleosides, uracil (2), uridine (3), 2'-deoxyuridine (4), 2'-deoxyinosine (5), guanosine (6), 2'-deoxyguanosine (7), thymidine (8), adenosine (9), and 2'-deoxyadenosine (10); three amino acids tryptophan (11), phenylalanine (12), and tyrosine (13); and two dopamine analogues N-acetylnoradrenaline (14) and its dimer, trans-2-(3',4'-dihydroxyphenyl)-3-acetylamino-7-(N-acetyl-2"-amino-ethylene)-1,4-benzodioxane (15). Their structures were decisively elucidated by spectroscopic analysis, including 1D and 2D NMR techniques.
