Abstract:
A HPLC method was established for simultaneous determination of two organic acids(chlorogenic acid and ferulic acid) and five phthalides(senkyunolide I, senkyunolide H, senkyunolide A, ligustilide, and butylidenephthalide) in Angelicae Sinensis Radix and its processed products to clarify the underlying material transferring rules. The analysis was performed on a Welch Ultimate C_8 column(4.6 mm×250 mm, 5 μm) with acetonitrile(A)-0.085% phosphoric acid water(B) as the mobile phase in a gradient elution mode at the flow rate of 1.1 mL·min~(-1), the column temperature of 25 ℃, the detection wavelength of 280 nm, and the injection volume of 10 μL. Under these conditions, the content of the above-mentioned seven components was analyzed in 15 batches of Angelicae Sinensis Radix and its processed products, and the transfer rate of each compound was calculated. As a result, in the processed products, the average content of chlorogenic acid was slightly decreased and that of ferulic acid was equivalent to the medicinal materials. The content of senkyunolide I, senkyunolide H, senkyunolide A, and butylidenephthalide showed an increasing trend in the processed products as compared with the medicinal materials. The mass fraction of ligustilide in the medicinal materials was above 0.7%(0.94% on average), meeting the requirement of 0.6% in the Hong Kong Chinese Materia Medica Standards, but was 0.47% on average in the processed products, which was decreased by 50% approximately. Further investigation showed that the content of ligustilide in freshly made processed products of Angelicae Sinensis Radix did not change significantly compared with that in the medicinal materials, indicating that the loss of ligustilide in the processed products mainly occurred in the storage. Therefore, Angelicae Sinensis Radix is suitable for storing in the form of medicinal materials and the freshly made processed products should be used except for special cases. Additionally, it is recommended to control the content of volatile oils or ligustilide in medicinal materials and processed products of Angelicae Sinensis Radix to ensure its effectiveness in clinical medication.
