ACETYLATED ALKALOIDS FROM NARCISSUS-PSEUDONARCISSUS

Three new alkaloids, 10-norpluviine, 1-O-acetyl-10-norpluviine and 1,1 0-diacetyl-10-norpluviine, have been found in bulbs of Narcissus pseud onarcissus. The known O-acetylgalanthamine is reported for the first t ime as a natural product. 1,10-Diacetyl-10-norpluviine and O-acetylgal anthamine were identified by means of gas chromatography-mass spectrom etry and were prepared from 10-norpluviine and galanthamine. By COLOC and NOE experiments it was shown that 10-norpluviine is not identical with norpluviine, which should be named correctly as 9-norpluviine.
