Abstract:

To address the issues of anthocyanin content and the types of monomeric anthocyanins in mulberries from the Yunnan region, 39 varieties of mulberries were investigated and analyzed for their anthocyanin content. The total anthocyanin content was determined using the pH differential method, the monomeric anthocyanin content was measured using high-performance liquid chromatography (HPLC), and the absorbance of red pigments in the edible parts of the mulberries was detected using spectrophotometry. The results showed that total anthocyanins were detected in 32 out of the 39 mulberry samples, and four types of monomeric anthocyanins were identified: cyanidin, pelargonidin, peonidin, and malvidin. Cyanidin was detected in 36 samples, pelargonidin in 33 samples, peonidin in 1 sample, and malvidin in 4 samples. Red pigments were detected in all 39 samples, with darker-colored mulberry fruits exhibiting higher red pigment content. The varieties ‘YX002’, ‘Hongguo 2’, ‘Jialing 30’, ‘Mengtong 4’, and ‘YX001’ has exhibit high levels of red pigments and anthocyanins, along with a rich diversity of monomeric anthocyanins. Among these, ‘YX002’ can have the highest total anthocyanin content, reaching 59.05 mg/L, and both cyanidin and pelargonidin also be detected in this variety.
