Abstract

The invention provides a UPLC detection method for various steroidal saponins in Chonglou yunnanensis or its multi-bud strains. The above detection method is simple, accurate, short in analysis time and good in stability, and can be used for detection of steroidal saponins in Chonglou yunnanensis or its multi-bud strains.

Description

Technical field [0001] The invention relates to the field of quality detection of Chinese medicinal materials, in particular to a UPLC detection method for various steroidal saponins in Yunnan Chonglou or its multi-bud strains. Background technique [0002] The first edition of the Pharmacopoeia of the People’s Republic of China in the 2015 edition contains the species of Liliaceae Parispolyphylla Smith var.yunnanensis (Franch.) Hand.-Mazz. or Parispolyphylla Smith var.chinensis (Franch.) Hara The dry rhizomes have the effects of clearing heat and detoxification, reducing swelling and pain, cooling the liver and relieving shock. Modern studies have shown that Chonglou has anti-tumor, hemostasis, immune regulation, sedation, and analgesic effects, and steroidal saponins are the main active ingredients that play a role. In recent years, due to the huge market demand for heavy buildings, endangered wild resources, high requirements for artificial breeding technology, and long culti...
