Maytenus aquifolium

Despite the broad medical potentials reported so far, the total synthesis of triterpene QMs is yet to be reported. On the contrary, the biosynthesis of triterpene QMs has recently been validated as from the oxidosqualene 88 (Scheme 8.16) in the plants including Maytenus aquifolium and Salacia campestris.10S With the assistance of HPLC analysis and isotopic labeling, it was found that triterpene QMs 90 were formed only in the root of these plants from friedelin 89 and similar cyclized intermediates, which were synthesized in the leaves from oxidosqualene by cyclase. [Pg.285]

Corsino et al. [22] reported that friedelane and quinonemethide biosynthesis is compartmentalized in Maytenus aquifolium and Salacia campestris, indicating cyclase activity in the leaves but not in the root bark. In order to confirm the possible translocation of friedelin derivatives, from the leaves to root bark, a solution of ( )5-3H-mevalonolactone was administered to the leaves of M. aquifolium seedlings. No labeled friedelin was detected in the root bark but, nevertheless, label quinonemethides were found. [Pg.639]
