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 0004: a, b. Cross-section of leaf c. Surface section of leaf. Upper epidermis (ue), xylem (x), phloem (ph), vasculary bundle sheath (bs), vascular bundles (vb), lower epidermis (le). Stoma (st), spongy parenchyma (sp), palisade parenchyma (pp), epidermis (e)

Mentions: In a cross section of the leaf, cuticle of the lower epidermis was thicker than of the upper one [Table 1]. Both epidermis cells were almost isodiametric, rectangular, and papillose [Figure 4a]. Although mesophyll consisted of nearly same type cells, palisade, and spongy parenchyma cells were differenciated. Palisade tissue seemed similar to spongy parenchyma cells because palisade tissue spreaded out infrequently in the leaf and had relatively large intercellular spaces. Cells under the upper epidermis, which were perpendicular to the surface, thin, and elongated longitudinally pointed out that these were palisade parenchyma cells [Figure 4b]. Palisade parenchyma cells were 1–3 layered whereas spongy parenchyma cells were 4–5 layered. Vascular bundles except the midrib were embedded in mesophyll. They had collateral structure type. There was not sclerenchymatic tissue in the bundles but parenchymatic bundle sheath was present [Figure 4ab].
