Trichocladabiflavone A, a chalcone-flavonone type biflavonoid from Alsto.

A chalcone-flavonone type biflavonoid, trichocladabiflavone A (), along with eight known biflavonoids () were isolated from the 70% EtOH extract of . Their structures were elucidated by extensive spectroscopic analyses. Compound was the first chalcone-flavonone type biflavonoid reported in the genus .

Palhinosides A-H: Flavone Glucosidic Truxinate Esters with Neuroprotective Activities from .

Palhinosides A-H (-), new flavone glucosidic truxinate esters, including β-truxinate and μ-truxinate forms, were isolated from . Their structures were elucidated by extensive spectroscopic methods and chemical analyses. The flavone glucoside cyclodimers possess a unique cyclobutane ring in their carbon scaffolds.

Neolignans and serratane triterpenoids with inhibitory effects on xanthine oxidase from Palhinhaea cernua.

Three new neolignans, lycocernuasides B-D (1-3), three new serratane triterpenoids, lycernuic ketones D (8) and E (9), and lycernuic A (10), together with six known compounds, were isolated from the 75% aqueous EtOH extract of Palhinhaea cernua. Their structures and absolute configurations were established primarily by NMR, HRESIMS and circular dichroism (CD). All compounds were evaluated the inhibitory activities of xanthine oxidase.

Two new compounds from the green peel of Juglans mandshurica.

A new cyclic diarylheptanoid (1) and a new flavone glucoside (2), along with seven known compounds, were isolated from the green peel of Juglans mandshurica. Their structures were elucidated based on extensive spectroscopic analyses. Moreover, the cytotoxicity against NCI-H460, A549, and K562 cancer cells of compounds 1-6 was evaluated.

New Selaginellin derivatives from Selaginella tamariscina.

Two new selaginellin derivatives selaginellin P (1) and selaginellin Q (2) were isolated from Selaginella tamariscina. The structures of 1 and 2 were established as 2,4'-dihydroxy-4-methyl-3-[(4-hydroxyphenyl)ethynyl]biphene (1) and 2,4'-dihydroxy-3-[(4-hydroxyphenyl)ethynyl]biphene (2) on the basis of spectroscopic means including HR-ESI-MS, 1D, and 2D NMR experiments.

Unciflavones A-F, six novel flavonoids from Selaginella uncinata (Desv.) Spring.

Six new flavonoids, unciflavones A-F (1-6), have been isolated from medicinal plant Selaginella uncinata (Desv.) Spring. Their structures were established on the basis of extensive NMR analysis including 1D NMR ((1)H, (13)C and DEPT) and 2D NMR (COSY, HSQC, HMBC) experiments as well as HRESIMS analysis.
