Summary: | •The volatile compounds of Rosa roxburghii Tratt samples from 4 origins were extracted by SAFE, HS-SPME.•143 volatiles were identified in Rosa roxburghii Tratt.•45 odor-active compounds were determined by GC-O.•Sensory attributes, odor-active compounds and origins were correlated by PLSR.
Rosa roxburghii Tratt (RRT) has become popular owing to its high vitamin C content. Volatiles are important factors that affect the quality of RRTs and their processed products. In this study, volatile compounds were extracted using headspace-solid phase microextraction (HS-SPME) and solvent-assisted flavor evaporation (SAFE); 143 volatile compounds were identified by gas chromatography-mass spectrometry (GC–MS), and RRT from different origins were well distinguished based on principal component analysis. 45 odor-active components were identified using gas chromatography-olfactometry (GC-O). Through quantitative descriptive analysis (QDA), there were prominent “grassy” and “tea-like” attributes in RRT. Partial least-squares regression (PLSR) revealed that Longli RRT was greatly related to “tea-like” and “woody” attributes. Among the volatiles identified, alcohols and esters were considered the dominant volatile compounds of RRT, 4-methoxy-2,5-dimethyl-3(2H)-furanone was the most prominent compound. This study enriches the flavor chemistry theory of RRT and provides a scientific basis for optimizing the aroma of RRT and its processed products. |
