Abstract: Two tetrahydroisoquinoline alkaloids were extracted from the alkaloid fraction of a methanol extract of the seeds of Calycotome Villosa Subsp. intermedia. Their structures were established as (R)-1-hydroxymethyl-7-8-dimethoxy-1,2,3,4-tetrahydro- isoquinoline (1) and (S)-7-hydroxymethyl-2-3-dimethoxy-7,8,9,10-tetrahydroisoquinoline chloride (2) by spectroscopic techniques and X-ray diffraction analysis.
Keywords: Calycotome villosa (Poiret) Link Subsp. Intermedia; alkaloids; tetrahydroisoquinoline; spectroscopy; X-ray crystal structure determination. Calycotome villosa (Poiret) Link Subsp. Intermedia; alkaloids; tetrahydroisoquinoline; spectroscopy; X-ray crystal structure determination.
