**2.5.** *Hoslundia* **genus**

*Hoslundia* genus is represented by one species in SA *vizH. opposite*. The phytochemical studies of the aerial parts yielded an interesting and rare pyrano and furanoflavonoid derivatives in addition to euscaphic and (**13**) ursolic acid (**11**) [19, 20]; four abietane-type esters, 3-*O*-cinnamoylhosloppone (**14**), 3-*O*-benzoylhosloppone (**15**), 3-*O*-benzoylhosloquinone (**16**), and 3-*O*-benzoylhinokiol (**17**); 13 was found to exhibit MIC of 50 μg/mL against *M. tuberculosis*, while 14 inhibits the growth of the MDR strain K1 of *Plasmodium falciparum* in vitro with an IC50-value of 0.4 μg/mL [21].
