Isolation of four ecdysones from Ajuga iva roots and a rapid semiquantitative method for ecdysone determination.
The ethereal extract of AJUGA IVA (L.) S CHREB. 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%).
