摘要: Qualitative analysis of the nonanthocyanin phenolics from 2 mulberry cultivars, da-10 and hongguo, was performed by HPLC-DAD-ESI-MS/MS method. Six compounds were identified (procatechuic acid, chlorogenic 4-caffeolyquinic taxifolin, rutin, quercetin) 3 others (3,5-diCQA, taxifolin-hexoside, kamepferol-hexoside) tentatively identified. Quantification phenolic HPLC-DAD, which revealed that rutin (111.38 90.79 microg/g FW) major in cultivars. Phenolic acids cultivar (54.68 far more than hongguo (14.93 FW).

These results relevant to not only control color stability organoleptic characteristics juice wine but also exploitation functional foods made mulberry.
