Identification and quantification of the fatty acids and isolation of (+)-pinitol, liriodenine, and (−)-N-acetyl-anonaine from empty capsules of Michelia champaca fruits. Crystal structure of (−)-N-acetylanonaine

Experimental and theoretical study on spectral features, reactivity, solvation, topoisomerase I inhibition and in vitro cytotoxicity in human HepG2 cells of guadiscine and guadiscidine aporphine alkaloids

“…The theoretical geometry optimization results of the studied molecules G1 and G2 ( Fig. 1 ) calculated at DFT B3LYP/6-311 G ++ (2df,3p) level of theory were compared with X-ray data of ( −)-N -acetyl-anonaine presented in literature [32] (see Table 1…”
