Patchouli [Pogostemon cablin (Blanco) Benth.] is an aromatic, herbaceous plant belonging to the Lamiaceae family native to Southeast Asia. Its leaves produce an essential oil regularly used by the perfume and cosmetics industries. However, since patchouli from the Philippines and India were described and named Pogostemon patchouli, there has been a divergence in the identity of these species. The objective of the current study was to study the genetic diversity of patchouli accessions in the Active Germplasm Bank of Universidade Federal de Sergipe using microsatellite and inter simple sequence repeat markers. The results of both types of molecular markers showed that there are two well-defined clusters of accessions that harbor exclusive alleles. It was observed that these two clusters are genetically distant, suggesting that they belong to two different species. Based on the results, two accessions were classified as Pogostemon heyneanus and the remaining accessions were classified as P. cablin.
广藿香[Pogostemon cablin (Blanco) Benth.]是一种芳香草本植物，属于唇形科，原产于东南亚。其叶子能产生一种香精油，常用于香水和化妆品行业。然而，自从来自菲律宾和印度的广藿香被描述并命名为Pogostemon patchouli以来，这些物种的身份就出现了分歧。本研究的目的是利用微卫星和简单序列重复区间标记，研究塞尔希培联邦大学活性种质库中广藿香种质的遗传多样性。两种分子标记的结果都表明，有两个明确的种质聚类，它们含有独特的等位基因。据观察，这两个聚类在遗传上相距较远，表明它们属于两个不同的物种。基于这些结果，两个种质被归类为水香薷，其余的种质被归类为广藿香。
