Anatomical investigations on root, stem, and leaf of Gentiana olivieri Griseb.

Tüzün CY, Toker MC, Toker G - Pharmacogn Mag (2011)

Bottom Line: Gentiana olivieri Griseb. (Afat) (Gentianaceae), which has many bioactive compounds is used as antidiabetic, hepatoprotective, digestive aid, antidepressant, and antianemic in traditional medicine.Anatomical characters of the species were observed to be similar to the usual features of Gentianaceae anatomy.Intraxylary phloem, which was primarily the distinguishing feature between Gentianoideae and Menyanthoideae sub-families was observed in G. olivieri roots.

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.

Figure 0003: a, b. Cross-section of stem. Epidermis (E), cortex (C), sclerenchymatic ring (ScR), vascular bundles (Vb), pith (P), xylem (X), phloem (Ph)

Mentions: There was a cuticular layer, and 6.05 ± 1.7 µm thick. A single layer epidermis cells were isodiametric. Epidermis provided with 4–5 wings with the participation of parenchymatic cells of the cortex tissue [Figure 3a]. Cortex cells, which had large intercellular spaces were 3–6 layered and 4.29 ± 1.7 × 6.87 ± 2.34 µm in size. Underneath the epidermis, there was sclerenchymatic ring consisting of small, multi-layered cells surrounding the central cylinder, which was composed of parenchymatic tissue with thin primary cell walls (Thickness of sclerenchymatic ring was 205.6 ± 43.26 µm). Vascular bundles were in many (41–46) small groups [Figure 3b]. The xylem comprised tracheid with a regular single strand. The phloem was 1–2 layered and consisted of sieve-tube elements. Interfascicular cambium was absent and arrengement of vascular bundles were collateral. Bundles were surrounded by bundle sheath. There were large parenchymatic cells in pith. Crystalline structures were not observed.
