Abstract A new dibenzo- p -dioxin biphenyl bisbenzylisoquinoline alkaloid, pachyovatamine, has been isolated from an extract of the leaves and stems of Pachygoneovatafrom Sri Lanka. The alkaloid was characterized by a consideration of its physicochemical data and conversion to O -acetyltiliacorinine. Pachygonamine, N -methylpachygonamine and tiliamosine were also isolated from the same extract.

bioconversion into nortiliacorinine A. Parallel feedings of (+)-(S)- and (-)-(R)-N-methyl-coclaurines and (-)-(S)-, and ( + )-(R)-coclaurines revealed that the stereo-specificity is maintained in the biosynthesis of nortiliacorinine A from 1-benzylisoquinoline precursors and established ‘S,S’-configuration at the two asymmetric centres in nortiliacorinine A.

Neben den bekannten Alkaloiden Tiliacorinin (1), Nortiliacorinin A (2) und Tiliacorin (3) wurde Yanangcorinin (4) als neues Bisbenzylisochinolin‐Alkaloid vom Dibenzodioxin‐diphenyltyp isoliert und seine Struktur durch spektroskopische Methoden und chemische Umwandlung bewiesen.
Sublingual dosage forms comprising a bitter active ingredient (including sildenafil, tadalafil, tetrahydrocannabinol, and cannabidiol) and a bitterness reducing agent are described. Methods of treating sexual dysfunction by administering the sublingual dosage form to an individual in need thereof are also described.
