Mallotus repandus

Jacoumaric acid (200) and jacarandic acid (201) have been isolated from Jacaranda caucana. Three new 13 H-ursane lactones (202)—(204) have been reported from Mallotus repandus. Other new compounds include barbinervic acid (205) from the leaves of Clethra barbinervis and the bauerene derivative myrtifolic acid (206) from the bark of Mesua myrtifolia. ...

The following example describes the results of the dereplication of an HTP fraction library for inhibition of melanin formation in an in vitro assay with a B16 cell line [54]. Briefly, following the inhibition and cell viability assay, the active organic extract from the whole plant of Mallotus repandus was fractionated with HTP. All of the HTP fractions were tested for melanin inhibitory activities. As shown in Figure 8, there are three major peaks exhibiting > 50% inhibitions of melanin synthesis and seven minor peaks exhibiting weaker inhibitions. The sharp activity peaks indicate the quality of the separations, which distributed the active components in three to five cells.
