title: Levels of lantadenes, bioactive pentacyclic triterpenoids, in young and mature leaves of Lantana camara var. aculeata.
abstract: Levels of the lantadene pentacyclic triterpenes were quantified in young and mature leaf samples of Lantana camara var. aculeata, by HPLC. The amount of different lantadenes (mg/100 g dry wt.) in young and mature leaf samples, respectively, was: lantadene A, 491.5 +/- 6.3, 805.9 +/- 52.8; lantadene B, 347.0 +/- 3.0, 522.3 +/- 37.1; lantadene C, 191.3 +/- 10.3, 424.8 +/- 39.1; lantadene D, 49.7 +/- 5.3, 177.4 +/- 19.0; reduced lantadene A, 19.1 +/- 2.3, 28.7 +/- 4.5; reduced lantadene B, 13.0 +/- 1.3, 18.6 +/- 1.2; and 22 beta-hydroxyoleanonic acid, 82.5 +/- 11.4, 167.7 +/- 30.1.
