Macedonic acid

Macedonic acid has now been shown to be (133) it was converted into the known 3)3,21 a-diacetoxyisoglabrolide (134). New oleananes include barrinic acid (135) from Barringtonia acutangula and 11-oxo- -amyrin (136) and its... 

Macedonic acid diglucuronide (102) has been isolated from G. echinata and G. pallidiflora by Kusano et al. (219). The saponin also occurs in G. macedonica, but not in G. uralensis and G. glabra (private communication from Dr. Kusano he and his co-workers consider that G. macedonica is a separate species from G. echinata).
