Abstract:
Hesperidin, the major flavonoid in citrus species, possesses various biological functions and pharmacological activities, however, its insolubility in water limits its bioavailability and medical or food application. When 8 g/L octenyl succinic anhydride modified sweet potato starch (OSA-SPS) with degree of substitution 0.0051 was applied to solubilize hesperidin under the conditions of stirring the mixture for 6 h at 2400 r/min, 50 °C and unadjusted pH, the solubilization efficiency of hesperidin was 6.52 folds higher than that without OSAS addition. It was noteworthy that the solubilization of hesperidin was obviously different from that of hesperetin (hydrolysate of hesperidin) either in starch origin of OSAS or in the influence of external factors. The interaction between OSA-SPS and hesperidin had been certified by means of FT-IR, XRD, DSC, 1H/2D NMR. These results would give a fundamental reference for probing specific mechanism between hesperidin and OSAS in the further research.

The carboxylate ion acts as a nucleophile that attacks the carbonyl carbon of the acid chloride to form a tetrahedral intermediate. Subsequently, the re-formation of the carbonyl group with the loss of the chloride ion as a leaving group leads to the formation of an acid...

However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.

The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
