GC fingerprinting of Lignum dalbergia odoriferae / 中成药

ABSTRACT

Objective: To establish the GC fingerprinting of Lignum dalbergia odoriferae. Methods: The measurement conditions applied are as follows DB 5 (0.32mm?30m 0.25?m) column; detector FID; internal standard tetradecyl alchohol. Results: Fingerprint of Lignum dalbergia odoriferae consisted of 7 peaks. The area of peaks exceeded 90% of total one. RSD of precision and reproducibility is in the range of 5%. Conclusion: The method can be used for quality control of Lignum dalbergia odoriferae.
