Studi Anatomi Dan Histokimia Daun Dan Cabang Tanaman Johar (Senna siamea (Lam.) H.S. Irwin & Barneby)

---

Johar (Senna siamea (Lam.) H.S. Irwin & Barneby) is one of species in Leguminosae family. Pharmacognosic studies are a step in determining the identity and quality value of medicinal plants. A study in pharmacognosy is the observation of microscopic characters. The purpose of this study was to analyze the anatomical structure and histochemistry of the leaves and branches of the Johar plant as a reference for microscopic characters. The study was conducted from December 2018 to February 2019. The anatomical preparation had been camed out at the Microtechnics Laboratory and Botanical Laboratory, FMIPA, Universitas Riau. The research method used paraffin method, paradermal and histochemistry. This study found each organ consist of three components dermal, ground and vascular. Idioblast cells use lined up on the upper side of the lamina, insert collateral vascular and leaf edges are composed of sclerenchyma. Stomata are bifacial and parasitic while trichomes are unicellular types. The trichomes in the petiole and rachis found with multicellular and unicellular type. Multicellular are commonly found in petioles, whereas in rachis are unicellular trichomes. Branches have experienced secondary growth with periderm and cambium found. Calcium oxalate crystals are found in various forms such as druse, sand, prism and raphide in certain locations in each organ. Histochemical tests showed positive alkaloids, tannins and lipophils in each organ with similarities or differences in cell location.
Key words: anatomy, branches, histochemistry, Johar, leaflet.
