摘　　要：Pineappleweed(Matricaria discoidea DC.,Asteraceae)herb is an essential oil containing raw material with spasmolytic and anti-inflammatory activity.It is also rich in phenolics,which may be used in pharmaceutical practice.This study aimed to investigate the phenolic and amino acid composition and the hyporific and analgesic effects of the M.discoidea aqueous-ethanolic extract and its amino acid modifications.In addition,we developed a polyethylene oxide gel formulation with M.discoidea extracts for the 3D-printed oral solid dosage preparations.In M.discoidea extracts,16 phenolic substances and 14 amino acids were established.The extract and its amino acid preparations revealed both analgesic and soporific activity in the studies with rodents.Amino acids enhanced these effects.Arginine,β-alanine,glycine,valine,and lysine potentiated the analgesic activity by 27%–64%,whileβ-alanine,glycine,and valine increased the soporific activity by 136%,176%,and 129%,respectively.The composition of the polyethylene oxide(PEO)printing gel with the M.discoidea extract was developed,and its printability was confirmed.The proposed 3D-printed medicines could be implemented for sleep disorders and painful conditions.
