Galium verum

Wool dyed with Rubia tinctorum and Galium verum Alizarin, quinalizarin, purpurin, xanthopurpurin, purpuroxanthin dimethyl ether, munjistin, rubiadin, nordamnacanthal, anthragallol, kermesic acid, hystazarin, emodin, quinizarin HCI/MeOH/ h2o A H20 B ACN with AcOH or FA 250 nm/ESI ( ) HPLC optimization... 

Analysis of dyed fibres allows identification of real colouring components of natural dyestuffs taking part in the dyeing process. Wool threads dyed with madder (Rubia tinc-torum) as well as Our Lady s bedstraw (Galium verum), were studied by HPLC DAD ESI MS" (SIM mode).[8] Chromatograms of the extracts from wool dyed with madder... 

In the threads dyed with Galium verum, purpurin and mbiadin were identified as the main components.

To prepare a painted fabric for comparative purposes, small bands of ferrous oxide, an alizarin/purpurin mixture, ground up bloodroot (Sanguinaria canadensis L.) and bedstraw (Galium verum L.) were painted on linen fabric (Testfabrics L-57). As carriers or binder for the pigment colorants to be painted on the fibrous materials, beef fat was used as a substitute for bear grease and egg white was used as source for albumin. The various combinations of these materials were mixed and painted on areas of the test fabric as outlined in Table III. The painted test fabric was left to diy for 24 hours.

Galium verum New extraction method. Pseudopurpurin is the main component, but purpurin, and in contrast to Rubia peregrina, alizarin can also be clearly identified. The red spot is, as in the case of Rubia peregrina, probably rubiadin. 

It is interesting to know that the plant yellow bedstraw Galium verum) has been used formerly in Britain to curdle milk although it never became a useful rennet substitute.
