Physicochemical characteristics and phytochemical profiles of yellow and red Physalis (Physalis alkekengi L. and P. pubescens L.) fruits cultivated in China.
Physicochemical characteristics and phytochemical profiles of red (Physalis alkekengi L., RP) and yellow (P. pubescens L., YP) Physalis fruits cultivated in three provinces of China were characterized. YP fruits showed significantly lower levels of total organic acids and elevated total sugars than those of RP. A total of 18 compounds was tentatively identified in hydromethanolic extracts of Physalis fruits applying HPLC-DAD-ESI-MSn and HR-ESI-MS. Cinnamoyl and hydroxycinnamoyl conjugates prevailed in both fruits. Diverse mono- and dihexosides of cinnamic, coumaric, caffeic, ferulic, and sinapic acid were found in YP, while RP merely contained feruloyl and sinapoyl hexosides. N,N´-dicaffeoylspermidine isomers were found in YP fruits, whereas N,N´-bis(dihydrocaffeoyl)spermine was exclusively detected in two of the RP samples. Additionally, two HDMF (4-hydroxy-2,5-dimethyl-3(2H)-furanone) hexosides were tentatively identified for the first time in YP. Both RP and YP fruits collected from three different provinces in China showed a significant intraspecific variability regarding their phytochemical profiles, despite their similar morphological fruit traits.
