Abstract
The extensive chemical investigation on the branches and leaves of Terminalia chebula var. tomentella (Combretaceae) led to the isolation of two new lignan glucosides with a furofuran skeleton, termitomenins F (1) and G (2). In addition, 19 known compounds including five lignan glucosides (3-7), six hydrolyzable tannins (8-13) and eight simple phenolics (14-21) were also identified. Their structures were determined by comprehensive spectroscopic analyses. It is noted that 8 and 9 were C-glycosidic hydrolyzable tannins with one hexahydroxydiphenoyl and one gallagyl group linked to an open-chain glucosyl C-1/O-2/O-3 and O-4/O-6, respectively, which were rarely found in plants. Nine known compounds, 6-9, 13, and 18-21, were procured from the titled plant for the first time, while 3-5, 10-12 and 14-17 were also found in the fruits. Notably, the known hydrolyzable tannins 8-13 exhibited stronger α-glucosidase inhibitory activities with IC50 values ranging from 0.10 to 3.12 μM, than the positive control, quercetin (IC50 = 9.38 ± 0.33 μM).

Abstract
A phytochemical investigation on the leaves of Tripterygium wilfordii Hook. F. was conducted, leading to the isolation of five undescribed dihydro-β-agarofuran sesquiterpenoids (1-5) and one known analogue (6). Their structures were determined by comprehensive spectroscopic analyses. The absolute configurations of the compounds were determined by comparison of the experimental ECD with the calculated data. In addition, all the compounds were evaluated for their neuroprotective activities against H2O2-induced cell injury in human neuroblastoma SH-SY5Y cells, and 3 showed the better protective effect with 76.63% cell viability comparing with the positive control Trolox (69.84%) at 12.5 μM.

Eleven sesquiterpenoids including four new eudesmane sesquiterpenoids, solanoids A-D (1-4), and seven known compounds (5-11) were isolated from the herbs of Solanum lyratum. By analyzing the UV, MS and NMR data, the gross structures of all isolates were established. The absolute configurations of these new compounds were determined by comparison of the experimental and calculated electronic circular dichroism (ECD) spectra. The in vitro cytotoxicity of all isolates against the hepatocellular carcinoma Hep3B and HepG2 cell lines was evaluated. Among them, compounds 7 and 11 exhibited moderate cytotoxicity against two cell lines.

Abstract
A phytochemical study on the fruits of Rubus idaeus L. (Rosaceae) yielded eight pairs of enantiomeric lignans, including one undescribed furolactone named (-)-idaeusinol A and six undescribed furofuran derivatives named (+/-)-idaeusinol B-D. The structures of these isolated compounds were elucidated by spectroscopic analyses and a combination of computational techniques including gauge-independent atomic orbital (GIAO) calculation of 1D NMR data and TD-DFT calculation of electronic circular dichroism (ECD) spectra. Bioactivity screenings suggested that (+)-idaeusinol D exhibited the most significant protective effect against H2O2-induced neurotoxicity at the concentration of 25 μM. In contrast, (-)-idaeusinol D, as the enantiomer of (+)-idaeusinol D, showed no effect against H2O2-induced neurotoxicity at both 25 and 50 μM concentration.

Abstract
Twelve previously undescribed phenolic meroterpenoids, cochlearols N-Y, along with two known analogs, ganocochlearins B and C, were isolated from the fruiting bodies of Ganoderma cochlear. Most of these substances were isolated as racemic mixtures. The structures of cochlearols N-Y were assigned based upon spectroscopic data and theoretical calculations. The renoprotective activities of these compounds were evaluated using normal and diseased rat renal interstitial fibroblast cells (NRK-49F). The results show that ganocochlearins S, U, X and Y display potent inhibitory activities against fibronectin overproduction in TGF-β1-induced NRK-49F cells.

Abstract
Encouraged by the in vivo anti-inflammatory effect of aqueous extract of Ilex asprella stems, a further phytochemical investigation on I. asprella stems oriented by the in vitro NO production inhibition in RAW264.7 cells was conducted, which led to the isolation of eight new phenolic constituents, namely asprenols A-H (1-8), together with 12 known ones (9-20). The structures of the new compounds were established by extensive spectroscopic data analyses of HR-ESI-MS, IR, UV, and 1D and 2D NMR, and the absolute configurations were determined by comparison of experimental and calculated ECD analyses. All isolated were evaluated for the inhibition against NO production in RAW 264.7 cells, and several compounds showed moderate inhibitory effect.
