title: [Effects of enhanced UV-B radiation on leaf anthraquinones content and cell ultrastructure of Aloe vera L].
abstract: By using transmission electron microscopy and high performance liquid chromatography, this paper studied the effects of enhanced UV-B radiation on the leaf anthraquinones content and cell ultrastructure of Aloe vera L. After treated with enhanced UV-B radiation 6 hours per day for 20 days, the total anthraquinone content, barbaloin content, and aloe-emondin content in A. vera leaves increased by 31.8%, 11.3%, and 22.0%, respectively, chloroplast envelope membrane was slightly damaged, but the structure of other organelles had no significant change. It was suggested that UV-B radiation could promote the accumulation of anthraquinone in A. vera leaves, but had less effects on the leaf cell ultrastructure.
