Compound Analysis and Genetic Study of Selected Plectranthus scutellarioides Varieties from Indonesia

Background: Plectranthus scutellarioides is one of medicinal plants in Indonesia, which has several hundred varieties but only one is known by local people as medicine. Objective: Six varieties of Plectranthus scutellarioides were analyzed for their total flavonoid content, chemical compound, and moleculer genetic. Methods: TFCs were analyzed using AlCl 3 colorimetric method, chemical compounds were identified using TLC-scanning densitometer, GC-MS, and FTIR, moleculer genetic were observed using DNA barcoding rbcL gene. Results: The TFCs of trailing psycholeus, and flamingo varieties were higher than the other varieties. TLC-scanner densitometer showed that color blaze dark star, trailing psycholeus, and trailing queen had similar profiles, as did beale street, trailing rose, and flamingo. The GC-MS results showed notable difference in trailing psycholeus and…
