TLC 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.
