title: [Standardization of the aerial parts of Alchemilla].
abstract: Dried aerial parts of Alchemilla xanthochlora Rothm. (16 batches), A. glabra Neygenf. (1 batch), A. coriacea Buser (2 batches) and A. filicaulis Buser (3 batches) present a similar flavonoid and tanin pattern. In the case of A. xanthochlora, the mean levels of the principal compounds were: total flavonoids 2.22%, glucuronyl-3 quercetol 1.18%, tanins 16.0% and ellagic acid 0.36%. The flavonoid levels were higher before flowering and the tanin levels higher during flowering. Four commercial batches were examined for a comparative study. Pharmacopoeial specifications were proposed for a revision of the monograph "Alchemillae herba".
