“…In previous studies, it has been reported that red betel leaf extract has been shown to have antiinflammatory effects (Wahjuni and Astawa 2016), (Ginting et al 2021), antidiabetic (Wahjuni et al 2017), antioxidants (Alfarabi et al 2010), antirheumatism (Maslikah et al 2019). From identifying phytochemical components, red betel leaf is reported to contain flavonoid, alkaloid, tannin-polyphenolic compounds, steroids, terpenoids and saponins (Lely et al 2021). Compounds that have been isolated from red betel leaf include pipercroside A and B phenolic glycosides (Li et al 2019);sitosterol and 2-(5', 6' dimethoxy-3', 4'-methylenedioxyphenyl)-6-(3", 4", 5"-trimethoxyphenyl)-3,7-dioxabicyclo [3,3,0] octane (Emrizal et al 2014), compound bicyclo[3.2.1]octanoid neolignans of guianin-type named as, (1′R, 2′R, 3′S, 7S, 8R)-Δ5′, 8′-2-acetoxy-3, 4, 5, 3′, 5′-pentamethoxy-4′oxo-8.1′,7.3′-neolignan (crocatin A) and (1′R, 2′R, 3′S, 7S, 8R)-Δ5′, 8′-2′-hydroxy-3, 4, 5, 3′, 5′-pentamethoxy-4′-oxo-8.1′,7.3′-neolignan (crocatin B) (Arbain et al 2018).…”
