Abstract
Rhubarb (Rheum officinale Baill.) is a species that belongs to Polygonaceae
family. Rhubarb has long been used in the traditional medicine. The metabolites
contained in rhubarb are rhein, emodin, chrysophanol and flavonoids. Anatomical
characteristics can describe the microscopic structure of a plant. Therefore, this
research was conducted with the aim of analyzing the anatomical structure of the
rhubarb stem through its anatomical characteristics. The stem used was 1-1.5
years old, which was cut 1 cm from the end and 7 μm thickness. The preparations
were stained using double staining, 1% safranin in water and 0.5% fast green in
95% alcohol. The result showed that secondary structure stem consisted of
feloderm with relatively elongated round cells; the cortex is composed of
parenchyma cells and had intercellular and pith that dominated the stem diameter;
and performed an open collateral-type bundle.
