Figure 9. Characterization of 430D-F5 major constituents.

Figure 9

(a) LC-FTMS ESI negative and positive base peak chromatograms for 430D-F5. All peaks correspond to data presented in Suppl. Table 4. (b) Putative structural matches are listed by peak number. Peak 2 was determined to be C30H17O10 and putative structural matches include: (2a) amentoflavone, (2b) agathisflavone, and (2c) robustaflavone. Peak 4 was determined to be C30H21O10 and putative structural matches include: (4a) chamaejasmin, (4b) tetrahydroamentoflavone, and (4c) tetrahydrorobustaflavone. Peak 14 was determined to be C30H45O4 and putative structural matches include: (14a) albsapogenin, (14b) (13α,14β,17α,20 R,24Z)-3α-hydroxy-21-oxolanosta-8,24-dien-26-oic acid, (14c) (13α,14β,17α,20 S,24Z)-3α-hydroxy-21-oxolanosta-8,24-dien-26-oic acid, (14d) (3α,13α,14β,17α,24Z)-3-hydroxy-7-oxo-lanosta-8,24-dien-26-oic acid, and (14e) mollinoic acid. Peak 19 was determined to be C30H45O4 and putative structural matches include (19) isomasticadienonalic acid.
