Anthraquinone and Naphthoquinone Derivatives from the Pericarps of Juglans sigillata

Chemistry of Natural Compounds, 2019
Four new anthraquinones (1–4), along with four known ones (5–8) and five known naphthoquinones (9–13), were isolated from the green pericarps of Juglans sigillata. The structures of the new compounds were elucidated as 1,3-diethoxycarbonyl-8-hydroxy-9,10-anthraquinone (1), 1,3-diethoxycarbonyl-5-hydroxy-9,10-anthraquinone (2), 1-ethoxycarbonyl-8 ...

Triterpenoids from Juglans sigillata and their anti-inflammatory and radical scavenging activity

Journal of Asian Natural Products Research, 2022
A phytochemical investigation on 90% methanol extract from the leaves of Juglans sigillata led to the isolation of three new triterpenoids, jugsigiloids A-C (1-3). Structural elucidation of all the compounds were performed by spectral methods such as 1 D and 2 D (1H-1H COSY, HMQC, and HMBC) NMR spectroscopy, in addition to high resolution mass ...

Comparative study of chemical compositions and antioxidant capacities of oils obtained from two species of walnut: Juglans regia and Juglans sigillata

Food Chemistry, 2019
This study compared the lipid compositions, minor components contents, oxidative stability index, and free radical scavenging capacities of walnut oils from two species in China: Juglans regia (common walnut) and Juglans sigillata (iron walnut). The results showed that iron walnut oil contained lower C16:0 (4.97-5.25%) and special fatty acid (erucic ...

[Study on diarylheptanoids from green peel of Juglans sigillata].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2019
The chemical constituents from green peel of Juglans sigillata were isolated by column chomatographies over silica gel, Sephadex LH-20, and MCI. Four diarylheptanoids were isolated and their structures were characterized as dihydropterocarine(1), 3',4″-epoxy-1-(4'-hydroxy-phenyl)-7-(3″-methoxyl-phenyl)-heptan-3α-ol(2), pterocarine(3), and 1-(4'-hydroxy-
