Functional Properties and Volatile Compounds of Baishouwu Flowers (Cynanchum Auriculatum)
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 3
Abstract
The well-known Chinese medical herb, namely Baishouwu owns an increasing interest, since its root extracts as well as fractions have considerable range of important pharmacological values. This work aims at studying the functional properties and volatile compounds of Baishouwu flowers. The study uses a Solid Phase Microextraction (SPME) with a Gas Chromatography coupled with a Mass Spectro- -metry (GC/MS). The results of our studies can be summarized as follows: the Water Absorption Index (WAI) of Baishouwu flowers equals 348.94 ± 0.5%, while the Oil Absorption Index (OAI) is 121.43 ± 0.2%. A good foaming capacity and stability value of Baishouwu flowers is reached, 11.7 ± 0.5 % after one hour. The bulk density of Baishouwu flowers is 0.54 ± 0.01 g/ml, which is essential for packaging as well as transportation. The swelling power of Baishouwu flowers reaches 9.74 ± 0.22 g/g, while the water solubility is 42.8 ± 0.7 %. Furthermore, total of 98 volatile compounds are detected. These include acids, aldehydes, alcohols, esters, hydrocarbons, ketones, furans, halogens, phenols, bases, lactones, flavors list, pyrans, coumarins in addition to other compounds.
