通过对番泻花和青果的植物化学研究，发现了一种新的取代的2,6-二烷基胡椒碱-3-醇生物碱，命名为(-)-7-羟基胡椒碱，以及已知的5种胡椒碱：(-)-cassine, (-)-spectaline, (-)-3- o- acetylspectaline, (-)-7-hydroxyspectaline和(-)- iso6 -spectaline。除非生物碱外，还鉴定了其他化学类的化学成分，包括类固醇β -谷甾醇、类黄酮木犀草素和3-甲氧基木犀草素、三萜白桦酸和反式肉桂酸。据我们所知，这些化合物是首次在该物种中被报道。
The phytochemical study of flowers and green fruits of Senna spectabilis furnished a new substituted 2,6-dialkylpiperidin-3-ol alkaloid, named (-)-7-hydroxycassine, along with five known piperidine alkaloids: (-)-cassine, (-)-spectaline, (-)-3-O-acetylspectaline, (-)-7-hydroxyspectaline and (-)-iso-6-spectaline. In addition to non-alkaloidal, chemical constituents from other chemical classes were also identified, including the steroid beta-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.
