Bioassay-guided fractionation of the roots of Myrica adenophora led to isolation of 24 known compounds and hitherto unknown compounds, including three A-type proanthocyanidins [adenodimerins A-C], two esters of sucrose [myricadenins A and B ], and the phenolic glycoside 6'-O-galloyl orbicularin. Spectroscopic analyses were used to determine their structures. Adenodimerin A, myricananin C, and myricetin showed strong 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities, with SC50… Expand

Biological Activities of Triterpenoids and Phenolic Compounds from Myrica cerifera Bark
TLDR
Seven triterpenoids, 1, two diarylheptanoids, 8 and 9, four phenolic compounds, 10 – 13, and three other compounds, 14 – 16, were isolated from the hexane and MeOH extracts of the bark of Myrica cerifera L. (Myricaceae) suggesting that 8 induced apoptosis via both mitochondrial and death receptor pathways in HL60. Expand
