Abstract
Three new benzophenone glycosides, 2-O-β-D-glucopyranosyl-6,3',4'-trihydroxy-4-methoxybenzophenone (1), 4'-O-β-D-glucopyranosyl-2,4,6,3'-tetramethoxybenzophenone (2) and 2-O-β-D-glucopyranosyl-4'-hydroxy-6-methylbenzophenone (3), and a new flavonoid glycoside 5'-hydroxyombuoside (6), along with three known phenolic glycosides 4-O-β-D-glucopyranosyl-2,6,4'-trihydroxybenzophenone (4), mangiferin (5), and ombuoside (7), were isolated from the 80% ethanol extract of roots of Dobinea delavayi. Their structures were determined by the comprehensive analyses of the physicochemical properties and spectroscopic data (1D NMR, 2D NMR, and HR-ESI-MS). Cytotoxicity and in vitro antimalarial activity of compounds 1, 3, 4, 6, and 7 were evaluated by MTT colorimetric assay and β-hematin formation inhibition assay, respectively.

Abstract
A new prenylated coumestan, campylohirtin A (1), along with fifteen phenolic known compounds (2‒16) and four other known compounds (17‒20), was obtained from the 95% ethanol extract of roots of Campylotropis hirtella. Their structures were elucidated based on extensive spectroscopic analysis (1 D and 2 D-NMR, MS, UV and IR). In vitro antimalarial activities of compounds 1-3, 5-14 and 16 were evaluated by β-hematin formation inhibition assay. Compared with the positive control chloroquine diphosphate, compounds 8, 11 and 16 exhibited strong antimalarial activity with the IC50 values of 69.9, 33.2 and 75.4 µM, respectively. Compounds 1-3, 5-7 and 12 showed moderate antimalarial activities with IC50 values ranging from 134.6 µM to 578.6 µM.[Formula: see text].

Abstract
Ten new ent-kaurane diterpenoids, including two pairs of epimers 1/2 and 4/5 and a 6,7-seco-ent-kauranoid 10, were obtained from the aerial parts of Isodon serra. The structures of the new compounds were confirmed by extensive spectroscopic methods and electronic circular dichroism (ECD) data analysis. An anti-inflammatory assay was applied to evaluate their nitric oxide (NO) inhibitory activities by using LPS-stimulated BV-2 cells. Compounds 1 and 9 exhibited notable NO production inhibition with IC50 values of 15.6 and 7.3 μM, respectively. Moreover, the interactions of some bioactive diterpenoids with inducible nitric oxide synthase (iNOS) were explored by employing molecular docking studies.

Abstract
Eleven new angeloylated eudesmane sesquiterpenoids, dobinins D-N (2, 3, 5, 6, 8, 9, and 11-15), and four known compounds (1, 4, 7, and 10) were isolated from the roots of Dobinea delavayi. A new oxidation product (8a) was also obtained from dobinin H (8). Their structures were elucidated by spectroscopic data and single-crystal X-ray diffraction analyses. Dobinins K-N (12-15) are the first examples of rearrangement noreudesmane analogue sesquiterpenoids with a unique 6/5-fused carbon skeleton. A putative biosynthetic pathway of compounds 12-15 is proposed. Compound 12 exhibited significant antimalarial activity superior to artemisinin with the inhibition ratio of 59.1%, and compounds 3, 5, and 15 exhibited moderate antimalarial activities against Plasmodium yoelii BY265RFP with inhibition ratios ranging from 14.5% to 18.5% at a dose of 30 mg/kg/day. In addition, the apoptosis of P. yoelii BY265RFP by the depolarization of mitochondrial membrane potential with striking ROS production, after parasitized erythrocyte lysis mediated by cytokines IL-12 and IFN-γ, may be a possible mechanism of antimalarial action of compound 12 against P. yoelii BY265RFP.
