Ursane‐ and oleane‐type triterpene glycosides from Ilex godajam

Abstract

Seven triterpenoid glycosides namely ilekudinoside D (1), kudinoside H (2), mateside (3), suavissimoside R1 (4), 3β‐[(α‐L‐arabinopyranosyl)oxy]‐19α‐hydro‐xyolean‐12‐en‐28‐oic acid 28‐β‐D‐glucopyranosyl ester (5), ilexoside XXXI (6), and silphioside B (7) were isolated from a methanol extract of the Ilex godajam branches and leaves by various chromatographic separations. Their structures were elucidated by extensive analysis of their NMR spectroscopic data as well as comparison of them with those reported. Compounds 1‐3 and 5‐7 were firstly isolated from I. godajam.

Phytochemical profile, in vitro anti‐inflammatory, and anti‐xanthine oxidase activity of durian fruit rind fractions (Durio zibethinus)

“…The LC/MS results revealed that fraction F2 from D. zibethinus fruit rinds contained various phytocompounds, including flavonoids, terpenoids, amino acids, stilbene glycosides (nonflavonoid), anthocyanins, and phenolics, consistent with previous studies (Masturi Alighiri et al ., 2020; Liu et al ., 2020b; Zhan et al ., 2021; Charoenphun & Klangbud, 2022; Cuong et al ., 2022). Notably, flavonoid compounds such as phlorizin and four different quercetin derivatives (quercetin‐3–O‐ arabinoside, quercetin glucoside, quercetin‐3‐O‐(6″‐trans p‐ coumaroyl‐2″‐gly) Rh, and dihydroquercetin‐glucosyl‐ rhamnosyl) were identified in fraction F2 (Table 4).…”
