Asparagus saponins: chemical characterization, bioavailability and intervention in human health

Abstract

In the last years, there has been increasing interest in the research on saponins from food sources. Many epidemiological studies have pointed out their versatile health benefits. Since saponins are directly associated with human dietary ingredients and health, there is a need to evaluate their structure and function relationship. Asparagus spears are one of the main dietary sources of steroidal saponins.Most recent researches have focused on the health aspects of asparagus saponins for humans. Many asparagus saponins have cytotoxic and antitumor activities together with cholesterol lowering effect. This review highlights the structural features of saponins in asparagus, their beneficial roles in human health, and as well as their bioavailability and role on diet.
