Platynecic acid

C10H14O4 Senecic acid lactone or Platynecic acid Platyphylline Senecionine 154-155 41.8° ... [Pg.115]

Senecic acid lactone was first isolated upon hydrolysis of senecionine by Barger and Blackie (43). It was compared directly and was found identical with platynecic acid by de Waal. Senecic acid lactone was also isolated upon hydrolysis of rosmarinine (6, 22) but Richardson and Warren (43a) found that senecic acid was obtained under certain conditions of hydrolysis and isolation. These workers proceeded to convert senecic acid to senecic acid lactone. They further indicated that differences in recorded physical properties and difficulties in the purification of this lactonic acid were probably due to the presence of mixtures of senecic acid and senecic acid lactone. [Pg.147]

Senecionine was extracted from the sources indicated in the following yields Senecio vulgaris L., 0.17% Senecio viscosus, 0.075% Senecio squcdi-dus, 0.06% Senecio aureus L., 0.006% Senecio ilicifolius, 0.02% Senecio pseudo-arnica, 0.02% Senecio integerrimus, 0.3%. On the basis of the structure postulated by Manske (19) for senecic acid lactone (platynecic acid), the structure of senecionine would be CIII. [Pg.159]
