Our studies report the isolation of seventeen compounds (1–17), which include three phenolic acids (12–14), seven flavonoids (3, 6, 8, 11, 15–17), four secolignans (1, 2, 5 and 9), one tetrahydrofuran lignin (10) and two alkaloids (4 and 7). These compounds have been obtained from the Peperomia tetraphylla using chromatographic methods. Their structures were confirmed based on spectroscopic methods. Among them, five compounds (4, 7, 8, 11 and 15) were found in the family, four compounds (3 and 12–14) were firstly reported from genus Peperomia, and four compounds (6, 9, 16 and 17) were firstly obtained from this species. Furthermore, the chemotaxonomic significance of these ingredients from the whole plants of P. tetraphylla has been discussed in detail.

我们的研究报告分离出了17种化合物（1–17），其中包括三种酚酸（12–14），七种类黄酮（3、6、8、11、15–17），四种豆蔻精（1、2、5和8）。 9），一种四氢呋喃木质素（10）和两种生物碱（4和7）。这些化合物已使用色谱法从四叶Peperomiatetraphylla获得。根据光谱法确认了它们的结构。其中，在该家族中发现了5种化合物（4、7、8、11和15），首先报道了Peperomia属中的4种化合物（3和12-14），以及4种化合物（6、9、16和17）。最初是从该物种获得的。此外，已经详细讨论了来自四叶假单胞菌整个植物的这些成分的化学分类学意义。
