In addition to the primary metabolites proteins, carbohydrates, and lipids, asparagus contains a large number of chemical constituents including flavanoids, amino acid derivatives, sulfur-containing acids, vitamins and saponins. Recent studies have indicated that some of these compounds possess health protective and pharmacological properties. We have initiated studies to examine saponins, α- tocopherol, and rutin in asparagus. The results confirmed that asparagus is a good source of these compounds. However, significant variations in their levels among different genotypes were observed. More studies are required to confirm the health benefits of these compounds.
