Dringo plant (Acorus calamus L.) is a medicinal plant with the main chemical components (major compound) is asaron (β-asarone) are commonly found in a rhizome, but did not rule these compounds are also present in other parts including leaves. β-asarone have high activity against Microsporum gypseum as antimicrobial, Trichopyton rubrum, and Penicillum marneffei and have anti-carcinogenic effects. This study aimed to determine the contents of β-asarone most of the leaves and rhizomes of plants dringo (A. calamus) by TLC-densitometry method. The leaves and rhizomes of each extracted by maceration method using n-hexane solvent. TLC performed on a standard profile and the sample was eluted with the eluent n-hexane: ethyl acetate (8: 2), then the TLC profiles scanned by TLCdensitometry at a wavelength of 313 nm maximum. The results showed levels of β-asaron on plant rhizomes dringo (A. calamus) leaves more than a ratio of 1: 0.58. β-asarone contained in the rhizome as 2743.49 mg / mL, while the leaves as much as 1593.63 mg / mL.
