Abstract

Background: Gentiana olivieri Griseb. (Afat) (Gentianaceae), which has many bioactive compounds is used as antidiabetic, hepatoprotective, digestive aid, antidepressant, and antianemic in traditional medicine.

Materials and methods: Root, stem, and leaf sections of G. olivieri were taken free hand or by sliding microtome and examined on light microscope.

Results: Anatomical characters of the species were observed to be similar to the usual features of Gentianaceae anatomy.

Conclusion: Intraxylary phloem, which was primarily the distinguishing feature between Gentianoideae and Menyanthoideae sub-families was observed in G. olivieri roots.

Keywords: Gentiana olivieri; Gentianaceae; root; stem and leaf anatomy.
