This invention discloses a
traditional Chinese medicine compound for
adjuvant chemotherapy in
colorectal cancer and its preparation method. The compound is made from the following raw materials in parts by weight: 15-30 parts of
Polygonum cuspidatum and 10-20 parts of Citrus aurantium. The preparation method includes: purification treatment, physical
primary cell wall disruption, sonic-
enzyme synergistic deep
cell wall disruption,
enzyme inactivation and stabilization, extraction process, concentration process,
alcohol precipitation purification,
macroporous resin-directed debittering, multi-component complex molecular inclusion,
bitter taste receptor antagonism and synergistic taste correction,
drying and shaping. This invention's compound, through the precise combination of
Polygonum cuspidatum and Citrus aurantium, achieves multi-target synergistic effects, which can reduce the toxic side effects of
chemotherapy, enhance the killing effect of
chemotherapy on tumors, directly inhibit the proliferation, migration, and invasion of
colorectal cancer cells, improve the
tumor microenvironment, and reverse
chemotherapy resistance. This invention has the advantages of significant chemotherapy synergistic effect, clear
toxicity reduction effect, high safety, and wide clinical applicability, and is suitable for
adjuvant chemotherapy treatment of
colorectal cancer.
