The quality of two samples (Indian and German mother tincture) of
Linn. prepared from marigold flowers have been evaluated on the basis of homeopathic literature. In addition to non-specific standards, two biomarkers, rutin and quercitin, have been used for microfingerprinting analysis of the samples of mother tincture. The results indicated the total absence of rutin in the Indian mother tincture whereas both rutin and quercitin were present in the German mother tincture. On the basis of these results a ratio calculation was performed. The study will be useful to manufacturers of homeopathic mother tinctures.
