Figure 1From: Simultaneous determination of five active compounds in chimonanthus nitens by double-development HPTLC and scanning densitometryTLC chromatograms of mixed standards and methanol extracts of Chimonanthus nitens for (A) one and (B) twice development on silica gel 60 TLC plate viewed (left) at λ = 365 nm and (right) after coloration with 1% vanillin-H 2 SO 4 solution. Mobile phase of chloroform-methanol (9‐1, v/v) was for the first development, and petroleum ether-ethyl acetate (10‐1, v/v) was for the second development. C1-C3 were three samples of Chimonanthus nitens derived from Wuyuan, Jiangxi Province. S, mixed standards; 1, scopoletin; 2, scoparone; 3, linalool; 4, β-caryophyllene; 5, cineole.Back to article page
