Abstract:

Lignan is considered one of the most important bio-active components in flaxseed, and has attracted attention in recent years because of the efficacies of anti-cancer, antioxidation, anti-inflammation, diabetes prevention and cardiovascular system protection. In order to make a better understanding of the exploitation and utilization of flaxseed lignan, based on the domestic and foreign literature reviews, this article mainly reviewed the research progress on the extraction technology and biological activity application of flaxseed lignan. The effective extraction of lignan from flaxseed is the basis of bioactivity research. Different extraction processes can not only cause the difference in the extraction rate of lignan, but also affect its biological activity. This article summarizes some commonly used extraction methods for flaxseed lignan, including organic solvent extraction, subcritical water extraction and microbial fermentation. At the same time, the application of bioactivities is summed up and the research progress of lignan in the pharmaceutical field is emphasized. This article proposes prospects for the future research direction of flaxseed lignan, aiming to provide theoretical basis for the in-depth research, development and application of flaxseed lignan in the fields of medical industry and health industry.

Key words: Flaxseed lignan, extraction technology, extraction rate, bioactivity
