[Analysis and study of total flavone and trace element in carthmus tinctorius L]

The content of total flavone in carthmus tinctorius L in Xinjiang was determined by ultraviolet spectrophotometry with scan from 200 to 400 nm where the maximum absorption wavelength was 267.00 nm. The contents of ten trace elements and constant elements in carthmus tinctorius L including potassium, sodium, calcium, magnesium, iron, chromium, nickel, manganese, copper and zinc were determined by flame atomic absorption spectrophotometry. The results showed that there were comparatively rich trace elements and high total flavone, among which are comparatively high calcium, magnesium, chromium, copper and zinc in carthmus tinctorius L. It provided useful data for discussing the relationship between the content of total flavone and the trace elements in carthmus tinctorius L, and for studing the relationship between the trace elements in carthmus tinctorius L and the cure for cardio-cerebral vascular disease.
