Abstract
The ethereal extract of Ajuga iva (L.) SCHREB. roots, yielded 4 ecdysones. Three were proved to be cyasterone, makisterone A and
ecdysterone, by using UV, IR, MS spectral methods and comparison with standard samples.
Spectral data indicate that the fourth ecdysone is similar to cyasterone but having
an additional hydroxy group in the side-chain.
The chromatographic pattern of ecdysone content in roots, stems and leaves is presented
as well as a rapid and simple Semiquantitative method for their estimation. The roots
had the highest total content (0.381%).
