Kết quả xác định tên khoa học và phân tích hàm lượng acid clorogenic của các mẫu kim ngân hoa thu tại Hải Dương và Hà Nam

Abstract

A total of 6 Lonicera samples were collected in different ecological areas in Chi Linh, Hai Duong and Thanh Liem, Ha Nam. The result of scientific name identification of 6 collected samples showed that 4 samples are Lonicera macrantha (D. Don) Spreng. species, 1 sample is L. confusa DC. species, and 1 sample is L. japonica Thunb. species. Chlorogenic acid contents of all collected samples are from 0.011 to 0.304%. Results also showed that the acid chlorogenic content of L. japonica Thunb. species is highest (0.304%), followed by L. confusa DC. species (0.055%). The chlorogenic acid contents of L. macrantha (D. Don) Spreng. are from 0.011-0.021%. These studies will help to identify Lonicera species currently in Hai Duong and Ha Nam provinces and select high-quality species (chlorogenic acid content) for plant production.
