Background: Lepidogrammitis drymoglossoides (Baker) Ching (L. drymoglossoides), a member of the Polypodiaceae family, was used in the treatment of numerous diseases. However, none of the potential ingredients and the quality control methods concerning this plant medicine was pronounced. Objective: To identify chlorogenic acid (CGA) from L. drymoglossoides and develop a high performance liquid chromatography (HPLC) assay of CGA. Materials and Methods: UV, TLC, and HPLC were utilized to identify the phytochemicals of L. drymoglossoides and determine the CGA content, respectively. The HPLC conditions were as following: a Phenomenex Luna C18 (2) (250 × 4.6 mm i.d.; 5 μm particle size; 100 Å pore size) column; the mobile phase of the mixture of acetonitrile and 0.5% aqueous phosphoric acid (11.5:88.5 v/v); the flow rate of 1.0 mL/min and determination wavelength of 327 nm. Results: The proposed HPLC method has been developed and validated. The calibration curve was y = 28328x + 16610 (R2 = 0.9997). The intra-day and inter-day precision and intermediate precision were validated with the RSD less than 5%. The mean recovery rate of the method ranged from 95% to 104%, with the RSD less than 5%. The LOD and LQD values were 0.049 and 0.132 mg/L, respectively. The content of CGA in L. drymoglossoides approximately reached 0.24% (v/v) by the proposed extraction and determination methods. Conclusion: The assay method was simple, convenient, and accurate to the quantification of CGA and can be used for the quality control of the herb.
