Using reverse-phase high performance liquid chromatography (RP-HPLC), the abundances of lawsone, quercetin, MNQ, and kaempferol were measured in HAEIBS (Figure 2) and were 19.32, 2.87, 31.15, and 64.98 mg/g, respectively (Table 1).
Of the 4 compounds isolated from HAEIBS, quercetin and kaempferol on nematodes have also been examined by our group.
