The structures of these compounds were determined on the basis of their SP 1 sp H NMR, SP 13 sp C NMR, and ESI-MS spectroscopic data, and by comparison with those previously reported in the literature as compounds B 1-13 b : I n i -hexacos-5,8,11-trienoic acid ( B 1 b ), -sitosterol ( B 2 b ), aurantiamide acetate ( B 3 b ), I cis i -9-octadecenoic acid ( B 4 b ), ( I Z i )-undec-4-ene ( B 5 b ), dodecyl ( I Z i )-9-hexadecenoate ( B 6 b ), neochlorogenic acid ( B 7 b ), chlorogenic acid ( B 8 b ), cryptochlorogenic acid ( B 9 b ), isochlorogenic acid B ( B 10 b ), 4,5-di I O i -caffeoyl quinic acid I n i -butyl ester ( B 11 b ), isochlorogenic acid A ( B 12 b ), isochlorogenic acid C ( B 13 b ). Then their chemical structures were determined by comparing the physical data ( SP 1 sp H NMR, SP 13 sp C NMR, ESI-MS) with the values given in the literature. It is worth noting that compounds B 1 b , B 3-6 b , and B 11 b were never isolated from this plant, while compound B 3 b has never previously been reported from the Asteraceae family. Fraction 4 was applied to a silica gel (mesh 300-400) column with a step gradient of petroleum ether and ethyl acetate (6:4->5:5), additionally isolated by Sephadex LH-20 column (trichloromethane-methanol, 1:1) to give B 4 b (280.6 mg) and B 5 b (4.8 mg).
