“…Therefore, this study has greatly enriched the chemical constituents and diversity. Among them, 15 flavonoids, including procyanidin B2 (peak 9) (Wang et al, 2017b), dihydromyricetin (peak 10) (Chu et al, 2018), (-)-epicatechin (peak 11) (Osman et al, 2019), puerarin (peak 12) (Wang et al, 2016), rutin (peak 24) (Sun et al, 2017), naringin (peak 28) (Ahmad et al, 2014), hesperidin (peak 32) (Li et al, 2019a), myricetin (peak 35) (Yuan et al, 2015), eriodictyol (peak 40) (Lei et al, 2020), quercetin (peak 41) (Saccol et al, 2019), naringenin (peak 43) (Zhu et al, 2015), kaempferol (peak 44) (Pan et al, 2018), diosmetin (peak 46) (Chen et al, 2019), nobiletin (peak 51) (Li et al, 2019a), and tangeretin (peak 53) (Li et al, 2019c), have been reported to have arthritis inhibitory effect in rats. Additionally, cinnamaldehyde (peak 8, phenylpropanoid) (Mateen et al, 2019), ursolic acid (peak 65, triterpenoid) (Kim et al, 2018), linoleic acid (peak 67, fatty acid) (Wang et al, 2011) and emodin (peak 54, other) (Zhu et al, 2013) were also exhibited anti-arthritis activities in vivo.…”
