Abstract EN
Processing of crude drug is a key character of traditional Chinese medicine (TCM), which could enhance the efficacy and/or reduce the toxicity of crude drugs to fulfill different requirements of TCM clinical practice.
Epimedii folium (EF) is a widely used TCM.
As a traditional method of TCM, EF is processed with refined mutton fat before being used in clinical practice.
It has been reported that processing EF with mutton fat could improve the bioavailability and intestinal absorption of epimedium flavonoids and thus enhances the pharmacological effects.
For economic benefits, it is possible to adulterate processed EF with unprocessed drug or process EF with cheaper plant oils.
In the present study, 17 batches of crude and processed EF samples were collected from the Chinese market and 10 batches of replica processed drugs were prepared with different edible plant oils and animal fats in our laboratory.
Elemental analyzer coupled with isotopic ratio mass spectrometry (EA-IRMS) was applied to determine the δ13C values of the cyclohexane extracts of those samples.
Significant differences could be observed in the results.
EA-IRMS could be used to discriminate raw EF, processed EF, and EF processed with C3 plant oils.
