Dong quai
Dong quai is the root of Angelica sinensis, a perennial in the carrot family (Apiaceae) cultivated mainly in Gansu province, China. Roots are dug in autumn, dried, sliced or milled, and sold as powder, slices or extracts made with water or ethanol. Extracts are often standardized to ligustilide or ferulic acid by HPLC, and the root is traded in TCM grades by size and origin.
Suppliers sell different products under the same name. Specify the one you need.
Dried, sliced root sold by grade for decoctions.
Dried, milled root for capsules and blends.
Water or ethanol extract with declared ferulic acid or ligustilide by HPLC.
Water decoction concentrated and granulated on a carrier, a common TCM format.
Compare each result with your own specification when the lot arrives.
Store root and powder sealed in lined containers, cool and dry; the oily root draws insects and mold if kept humid. Ligustilide is volatile and unstable, so extracts are kept sealed and out of light. Suppliers set shelf life or retest dates.
Marker content varies with origin, root age and processing, and fumigation practice varies by supplier. Record supplier lot, origin, SO2 result and assay, and rotate first-expiry-first-out.
