Some pale yellow microneedles, m.p. 175-176°, were obtained in 0.8% yield from the leaves of Aleurites cordata STEUD. (Euphorbiaceae) and the hydrolysis of this glycoside afforded 1 mole each of quercetin and rhamnose, identifying it as quercitrin (quercetin-3-rhamnoside). The leaves of Firmiana simplex W. F. WIGHT (Sterculia-ceae), Ficus carica L. (Moraceae), and Humulus-lupulus L. var. cordifolius MAXIM. (Moraceae) afforded the same glycoside as pale yellow needles, m.p. 176°, in 0.15, 0.1, and 2.0% respective yields. This was identified as rutin, affording 1 mole each of quercetin, glucose, and rhamnose by hydrolysis.
