Macroscopic Entries
| Spiraea Ulmaria L. (Filipendula Ulmaria (L.) Maxim.),
commonly known as Queen of the Meadow, or Meadow-sweet and many if not all the species of this genus contain a colorless volatile oil, very similar to the oil of gaultheria, but composed mainly of salicylic aldehyde, with only smaller amounts of methyl salicylate.
A yellow, crystalline powder of a bitter taste, insoluble in water, slightly so in alcohol, readily soluble in ether, and having an acid reaction. Spiraeaic acid (now recognized as salicylic acid) (J. Pr. Chem., xix) was separated from the flowers of S. Ulmaria by Lowig and Weidmann.
The roots of probably most of the species contain tannic acid, gallic acid, and when fresh some of the volatile oils.
