Among all varieties, color blaze dark star was the one commonly used in Indonesia as traditional medicine. Optimization extraction process, qualitative phytochemical analysis, and preliminary assessment of toxicity of color blaze dark star and trailing queen variety of Plectranthus scutellarioides were investigated. Extraction process in color blaze dark star variety using Microwave assisted extraction show the highest %yield of extract but in trailing queen variety the highest %yield of extract was obtained from soxhletation method. Qualitative phytochemical analysis using thin layer chromatography from methanol, ethanol, and water extract with all method of extraction showed that both of varieties of Plectranthus scutellarioides contain alkaloid, flavonoid, tannin, and phenol.
