From the whole plant of Klainedoxa gabonenses betulinic acid ( 1), lupeol ( 2), s-sitosterol ( 3), �- amyran-3-one ( 4) and 3,3',4'-tri-O-methylellagic acid ( 5) were isolated. Similarly paullinomide A ( 6), �-amyrin (7), 2-(4-hydroxy-3,5-dimethoxyphenyl)-3-hydroxymethyl-2,3-dihydro-1,4,5-trioxaphenanthren-6-one ( 8), 5�- poriferastane-3s,6 �-diol ( 9), �-sitosterol ( 3), l-quebrachitol ( 10 ), and s-sitosterol glucopyranoside ( 11 ) were isolated from roots of Paullinia pinnata. Preliminary studies showed that 2-(4-hydroxy-3,5-dimethoxyphenyl)-3- hydroxymethyl-2,3-dihydro-1,4,5-trioxaphenanthren-6-one ( 8) showed moderate algicidal activity against the alga Chlorella fusca
