alcaloides, também foram isolados constituintes químicos de outras classes como o esteroide β-sitosterol, os flavonoides luteolina e 3-metóxi-luteolina, o triterpeno ácido betulínico e o ácido trans-cinâmico. A partir do levantamento bibliográfico foi possível observar que os compostos estão sendo relatados pela primeira vez nesta espécie. The phytochemical study of flowers and green fruits of Senna spectabilis furnished a new substituted 2,6-dialkylpiperidin-3-ol alkaloid, named

In addition to non-alkaloidal, chemical constituents from other chemical classes were also identified, including the steroid β-sitosterol, the flavonoids luteolin and 3-methoxyluteolin, the triterpene betulinic acid and trans-cinnamic acid. To our knowledge, compounds are being reported for the first time in this species.
