Hesperetic Acid
in chemistry, C10H10O4, obtained by the action of alkalis on hesperidin. It melts at 225°.
Fused with caustic potash, it is decomposed into acetic and protocatechuic acids, hydrogen being liberated.
HESPERETIN (-per'e-tin), in chemistry, C6H5O2-C10H2O3. It is obtained along with glucose by the action of dilute acids on hesperidin. It is recrystallized from ether; the crystals are white, and melt at 223°. Hesperetin is really insoluble in alcohol. Heated to 100° with caustic potash, it yields hesperetic acid and phloro-glucin.
HESPERIA (-pē'ri-ä), in astronomy, an asteroid, the 69th found; discovered by Schiaparelli, April 29, 1861. In entomology, the typical genus of the family Hesperidæ. The species fly with extreme rapidity.
HESSE HESPERIDES (-per'i-dēz), in Greek mythology the name of the famous sisters (Ægle, Erythia, Hestia, Arethusa) who, assisted by the dragon Ladon, guarded the golden apples which Hera had received, on her marriage with Zeus, from Ge. With the assistance of Atlas the apples were stolen by Hercules, who killed the dragon.
