Hemiterpene glycosides and a phenylisobutanoid were isolated from P. scandens.
Hemiterpene glycosides, pothobanosides B and C, showed anti-estrogenic activity.
Hemiterpene glycoside, pothobanoside A, showed hyaluronidase inhibitory activity.
Pothobanoside C inhibited histamine release to the same degree as the positive control.
