A comprehensive evaluation of 25 common chrysanthemum varieties in China was carried out for their chemical constituents, antioxidant activity, and hepatoprotective effects. Initially, the water extracts from chrysanthemums were analysed using liquid chromatography-mass spectrometry and 29 chemical components were identified. It was observed that chrysanthemums were rich in chemical constituents with significant differences in the contents of phenolic acids and flavonoids among the varieties.

Afterwards, the antioxidant activities of different chrysanthemums were investigated through different assays. The relationships between nine main components and antioxidant activities were examined to identify the antioxidant constitutes in chrysanthemums. The study also examined the capacity for each cultivar to protect against cell damage, with certain cultivars standing out with higher efficacy.

The hepatoprotective effects of eight mainstream varieties were determined using a model of acute alcoholic liver injury. The chrysanthemums were found to protect the liver from injury by impacting relevant liver function and antioxidant indexes. Selected varieties could decrease certain liver activities, while others significantly decreased harmful content in liver tissue, showing significant antioxidant capacity.
