摘要(Abstract):

[Objective]To study the effect of shade on chemical constituents of the volatile oil in turmeric( Curcuma longa L.).[Methods]The volatile oil of turmeric under different degrees of the shade was extracted by steam distillation. The chemical constituents were analyzed by gas chromatography-mass spectrometry( GC-MS).[Results]34 constituents from turmeric under different degrees of shades were identified,accounting for 64. 10%,64. 33% and 70. 05% of total constituents,respectively,and the content of them decreased or increased with shading. Ar-turmerone is the main chemical constituent of the volatile oil,accounting for 44. 83%,47. 95% and 51. 90% of the total volatile oil,respectively,and the content was gradually increased with the increase in degree of shade.[Conclusions]There was a difference in the content of components of turmeric volatile oil under different degrees of shade,and increasing the degree of shade is conducive to the synthesis of arturmerone and other major active components in volatile oil.
