Abstract:
Objective To establish and improve the quality standard of ginkgo semen decoction pieces. Methods The morphological character for 29 batches of ginkgo gemen and 12 batches of stir-fried ginkgo gemen were observed, and the moisture contents were assayed using the method in Chinese Pharmacopoeia 2015 edition, the first supplement. Results The character of ginkgo gemen and stir-fried ginkgo gemen were consistent in different batches. The moisture content of ginkgo gemen was 8.8% to 12.2%, with an average of 10.5%. The moisture content of stir-fried ginkgo gemen was from 5.4% to 12.3%, with an average of 8.9%. Considering that ginkgo semen decoction pieces are stored for a long time, they are prone to the attack of mildew and insects, and the moisture limit is set to be no more than 10.0% in ginkgo gemen and stir-fried ginkgo. Conclusion Compared with the Chinese Pharmacopoeia 2015 edition, the first supplement, the character identification for ginkgo semen decoction pieces was added and the quality standards were improved. The moisture content of ginkgo semen decoction pieces needs to be strictly controlled under 10.0% to prevent mildew and insects.
