Bioactive Components
The major active constituents of Asparagus are steroidal saponins named as shatavarin I and shatavarin IV which are present in the roots. Asparagamine A, an alkaloid was isolated from root. Shatavarins are the glycoside of sarsasapogenin which are generally occurring in two types of skeletons furostanols and spirostanols rhamnose. 8-methoxy-5,6,4’-trihydroxyisoflavone a new isoflavone was isolated by roots of Aspargus (Saxena et al., 2000 and Aterya 1999).
