不同采收期对野菊花质量的影响
Effects of different harvesting periods on the quality of Chrysanthemi Indici Flos
摘要
Abstract
Chrysanthemi Indici Flos （YJH） samples of different harvesting periods （the bud period：HL，the early flowering period：CH，the full bloom period：SH，the final flowering period：ZH） were collected from September to October，and the stems&leaves（JY）samples of SH samples were collected synchronously. The HPLC fingerprint of the water extract of YJH samples was established and their antibacterial activities were determined. The results showed that the biomass of YJH samples was SH > CH > ZH > HL. The HPLC fingerprinting results showed：Along with the picking periods，the components of YJH samples water extraction varied from less to more，and their content increased gradually， which reached the peak during the full blooming period，and then declined. Results of antibacterial effects on Escherichia coli and Staphylococcus aureus showed the bud stage samples is the strongest，and the final flowering stage samples is poor. By comprehensive analysis of biomass，chemical composition，and antibiosis，harvesting YJH in the full blooming period could achieve the largest output of medicinal materials，better medicinal effects，and better quality. Meanwhile，harvesting in the full blooming period could save labor costs and realize comprehensive utilization of herbal resources，which is of great significance to achieve high-quality development of YJH industry.关键词
