Studying morphology and anatomy of Polysicas scutellarius (Burm. F.) Forsberg.

Abstract

   According to recent studies, the hexane and ethyl acetate extracts from leaves of Polyscias scutellarius (Burm. F.) Fosberg. could resistant to Acinetobacter sp., which was isolated on human skin. The leaves of this tree also contain compounds such as stigmasterol; spinasterol; 3-O-β-D-Glucopyranosylstigmasterol… Studying the morphological and anatomical features of P. scutellarius provides the basis for species identification and testing of medicinal herbs by microbiological methods. Roots, stems, petioles, leaf blades of fresh plant samples were cut into thin slices with a razor blade, and micro-stained with double dye alum green iodide. While other species in the genus Polyscias have a compound leaf pattern, P. scutellarius (Burm. F.) Fosberg. has a simple leaf pattern, the leaf margin is curved upwards, the leaf blade is like a fork, leaf veins shaped like feathers, prominent on the upper surface, leaf stem with joints; about the anatomical structure, P. scutellarius has cytoplasmic tubules, calcium oxalate crystals in organs, calcium oxalate crystals in the organs; the libe club on the stem and root are similar to the anatomical structure of P. fruticosa (L.) Harms. The morphological characteristics and anatomical structures of roots, stems and leaves of P. scutellarius (Burm. F.) Fosberg helps to identify species more exactly.
