Plants and resins identified for analysis were purchased at pharmacies in Dunhuang and Beijing, and at Chinese pharmacies the Los Angeles area. Items not available at pharmacies were acquired from botanical gardens in the United States and China. Some sources were purchased at the chemical market in Old Delhi, India. Validation of the species was necessary to ensure accuracy; this was done with Liquid Chromatography-Photodiode Array-Mass Spectrometry (LC-PDA-MSn).

A database will be designed to manage the acquisition, horticultural, and reference information for each biological source.
