Objective: Determined by HPLC method cinnamon single Fried fluid and cinnamon and red halloysite different proportion of gegenqinlian decoction of liquid water extraction fits the liquid and naphtha in cinnamic acid and cinnamaldehyde content

material basis from the pharmacodynamic changes of Chishizhi Wei on the role of the phase of cinnamon. Method :Take the cinnamon

cinnamon drew red halloysite and cinnamon compatibility of purified red halloysite three groups of compatibility of medicinal herbs

adopt heating reflux extraction and volatile oil extraction meanwhile extraction and collected water extraction liquid and naphtha two composition points

to extract use HPLC analysis. Adopt chromatographic column:Phenomenex-C18(4.6 mm×250 mm

5 μm)

column temperature 30 ℃

velocity was 1.0 mL ·min-1

detected wavelength was 254 nm

mobile phase was acetonitrile(A)-0.1% phosphate(B)

binary linear gradient elution 0-30 min

90% B-65% B(10% A-35% A);30-50 min

65% B(35% A)conditions

determination of water extraction fluid cinnamic acid and cinnamaldehyde content. Adopt chromatographic column:Phenomenex-C18(4.6 mm×250 mm

5 μm)

column temperature was 30 ℃.Velocity was 1.0 mL ·min-1

detected wavelength was 280 nm

mobile phase was acetonitrile(A)-0.1% phosphate(B)

0-30 min

65% B(35% A)conditions

determination of cinnamaldehyde content of volatile oil. Result: Cinnamon drew compatibility red halloysite and cinnamon purified water extract-alcohol compatibility red halloysite in liquid cinnamic acid content of single Fried cinnamon herbs according to drop respectively 30.71%

53.54%

cinnamaldehyde not detected. Volatile oil of cinnamaldehyde content decreased respectively 7.21%

75.89%. Conclusion: Cinnamon and red halloysite after cinnamic acid and compatibility of cinnamaldehyde content decreased

and drop extent with relevant red halloysite percentage.
