Percent Composition: C 43.90%, H 7.37%, O 48.73%
Literature References: Occurs free in poison sumac (Rhus toxicodendron L., Anacardiaceae), combined in the form of glycosides of many plants. Preparation: Clark, J. Biol. Chem. 38, 255 (1919). Structure and configuration: Fischer, Morrell, Ber. 27, 384 (1894); Fischer, Zach, ibid. 45, 3762 (1912); Hirst, Macbeth, J. Chem. Soc. 1926, 23; Avery, Hirst, ibid. 1929, 2466.

Derivative Type: a-Form
Properties: Always obtained by crystn from H2O or EtOH. Monohydrate, holohedric rods from water, hemihedric monoclinic columns from alcohol. Loses water of crystn on heating and partially changes to the b-modification. Very sweet taste. mp 82-92°: Ghosh, Proc. R. Soc. Edinburgh 36, 216 (1915/16). Sublimes at 105° and 2 mm Hg. d420 1.4708. Shows mutarotation. [a]D20 -7.7° ? +8.9°: Hudson, Yanovsky, J. Am. Chem. Soc. 39, 1032 (1917).
Melting point: mp 82-92°: Ghosh, Proc. R. Soc. Edinburgh 36, 216 (1915/16)
Optical Rotation: [a]D20 -7.7° ? +8.9°: Hudson, Yanovsky, J. Am. Chem. Soc. 39, 1032 (1917)
Density: d420 1.4708
 
Derivative Type: b-Form
Properties: Prepd by heating a-rhamnose monohydrate on a steam bath; crystallized from anhydr acetone + alcohol. Needles, mp 122-126° (rapid heating). [a]D20 +31.5° (1 min, p = 10). After a short time the rotation adjusts to the same final value as a-rhamnose. The b-form is hygroscopic and changes into crystals of the a-modification upon exposure to moist air.
