Two new ent-clerodane diterpenoids, named isoscoparins R and S (1 and 2), were isolated from the aerial parts of Isodon scoparius. Their structures were characterized mainly by analyzing the NMR and HRESIMS data, and the relative configuration of compound 1 was determined by single-crystal X-ray diffraction. Compound 2 showed weak activity as an autophagic inhibitor. [ABSTRACT FROM AUTHOR]

Two new C-glucosyl flavonoids 6′′-O-feruloylspinosin and 6′′-O-feruloyl-6′′′-p-hydroxybenzoylspinosin, together with five known compounds, were isolated from the seeds ofZiziphus jujube(Rhamnaceae family). Their structures were elucidated on the basis of chemical and spectroscopic evidences. Compounds1–7showed moderate inhibitory effects against COX-1 and COX-2 enzymes. [ABSTRACT FROM PUBLISHER]

The EtOH extract of the roots ofPaeonia veitchiiafforded two new monoterpene glycosides paeonidanin I (1)and paeonidanin J (2), and a new dimeric monoterpene glycoside paeonidanin K (3). Their structures were elucidated on the basis of spectroscopic means and hydrolysis products. [ABSTRACT FROM PUBLISHER]

The EtOH extract of the roots ofPaeonia lactifloraafforded a new phenolic glycoside paenoside A (1) and a new monoterpene glycoside paeonin D (2), and five known monoterpene glycosides. Their structures were elucidated on the basis of spectroscopic means and hydrolysis products. All compounds displayed inhibitory potential against enzyme lipoxygenase. [ABSTRACT FROM PUBLISHER]
