[Abstract] The genus Piper (Piperaceae) is widely distributed in the tropical and subtropical regions of the world, and species belonging to this genus are included in the Ayurvedic system of medicine and in folklore medicine of Latin America. Phytochemical investigations of Piper species have led to the isolation of several classes of physiologically active compounds such as alkaloids, amides, pyrones, dihydrochalcones, flavonoids, phenylpropanoids, lignans and neolignans. In an ongoing investigation of bioactive secondary metabolites from Piper species, herein, we describe the isolation procedure of nine flavonoids, including two chalcones and two flavanones from the leaves of Piper delineatum Trel. (Piperaceae), a shrub native to tropical regions of the ...
[摘要] 蓟属（Piperaceae）广泛分布在世界的热带和亚热带地区，属于该属的种属包括在医学的阿育吠陀系统和拉丁美洲的民间传说医学中。 对Piper物质的植物化学研究已导致分离几类生理活性化合物，例如生物碱，酰胺，吡喃酮，二氢查耳酮，类黄酮，苯丙素类，木酚素和新木脂体。 在对来自Piper种的生物活性次级代谢物的进行中的研究中，我们描述了九种类黄酮的分离程序，包括来自叶脉的两种查耳酮和两种黄烷酮 。 （Pi科），灌木本地对美洲的热带地区。 所有化合物通过光谱和光谱测定法进行阐明，并与文献中报道的数据进行比较。
