Abstract
Seven previously undescribed diterpenoids, tinocrisposides A-D (1-4) and borapetic acids A (5), B (6), and C (7), together with 16 known compounds, were isolated from the stem of Tinospora crispa (Menispermaceae). The structures of the new isolates were elucidated by spectroscopic and chemical methods. The β-cell protective effect of the tested compounds was examined on insulin-secreting BRIN-BD11 cells under dexamethasone treatment. Diterpene glycosides 12, 14-16, and 18 presented a substantial protective effect on BRIN-BD11 cells treated with dexamethasone in a dose-dependent manner. Compounds 4 and 17 with two sugar moieties exhibited clear protective effects on β-cells.

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2021; 69:1251-1258.

Abstract
A case of baled alfalfa hay contaminated with multiple weeds induced hepatotoxicity and death in cattle. The hepatotoxic compounds were isolated by bioassay-guided fractionation using a mouse model and identified as salviarin, salvianduline D, rhyacophiline, and 7-hydroxyrhyacophiline. The structure of 7-hydroxyrhyacophiline has not been previously reported. All compounds were found to induce severe acute hepatic necrosis within 24-48 h after a single oral dosage (260-280 mg/kg). The identified diterpenes are known to be found among different Salvia species which led to finding dried plant parts of Salvia reflexa within bales of weedy hay and subsequently a population of S. reflexa was found along the field edges and irrigation ditch banks of the alfalfa hay field. It was thus determined that S. reflexa was responsible for the hepatotoxicity observed in cattle fed the contaminated hay.

Abstract
Both DNA barcoding and phylogenetic data of the studied botanical material suggested the existence a new population of Galphimia glauca. Their leaves afforded three new nor-3,4-seco-friedelanes named galphimines M-O, together with known galphimines D, E, G, and I. Galphimines M and N possess bicyclic orthoacetates which are the first examples of orthoesters found in the Malpighiaceae family, while galphimine O has a 27,20-δ-lactone moiety. The structures elucidation followed from spectroscopic means and the absolute configuration followed from single crystal X-ray diffraction analyses. Tests for antibacterial and antifungal activities of galphimines N and M showed no promising effects.

Abstract
Four new neo-clerodanes, crotonolins C-F (3-6), were isolated from the stem bark of Croton oligandrus together with the known clerodane crotonzambefuran A, the abietanes 7-β-hydroxydehydroabietic acid and 7-oxodehydroabietic acid, and ferulic acid. Their structures were elucidated by spectroscopic analyses including 1D and 2D NMR and HRESIMS and by comparison with previously reported data. The cytotoxicity of the isolated compounds against A549, MCF7, PC3 and PNT2 cells was evaluated using the MTT assay. Only 7-β-hydroxydehydroabietic acid showed a moderate level of activity against PC3 cells with an IC50 value of 68.9 ± 6.6 µM.

Abstract
Six new phenolic acid derivatives, salviachinensines A-F (1-6), together with 14 known compounds (7-20) were isolated from the Chinese medicinal plant Salvia chinensis. The structures of salviachinensines A-F (1-6) were elucidated by NMR spectroscopy, bioinspired chemical synthesis, ECD analysis, and quantum chemical calculation methods. Compounds 2 and 3 are a pair of cis- trans isomers, and compounds 5 and 6 a pair of epimers. The solvent-induced isomerization of compounds 5 and 6 and the hypothetical biogenetic pathway of compounds 1-6, as well as the antiproliferative property and the ability of 1 to induce apoptosis and arrest cell cycle progression of MOLM-13 cells, were also investigated.

Abstract
New clerodane diterpenes, 12-epi-megalocarpodolide D (2) and an epimeric mixture of crotonolins A (3) and B (4), were isolated from the bark of Croton oligandrus following a bioassay-guided isolation protocol. Known compounds, megalocarpodolide D (1), 12-epi-crotocorylifuran (5), cluytyl-ferulate (6), hexacosanoyl- ferulate (7), vanillin (8), acetyl-aleuritolic acid (9) and lupeol (10), were also isolated. The structures of the isolated compounds (1–10) were elucidated by spectroscopic means. The cytotoxicity of compounds 1–10 was assessed against A549, MCF7, PC3 and PNT2 cell lines using the MTT assay. Compounds 1 and 2 showed moderate levels of activity against both A549 and MCF7 cells with 1 being the most active with IC50 values of 63.8 ± 13.8 and 136.2 ± 22.7 µM against A549 and MCF7 cells, respectively. The epimeric mixture of 3 and 4 was moderately active against A549 and PC3 cells (IC50 = 128.6 ± 31.0 and 111.2 ± 2.9 µM, respectively).

Abstract
Eleven neo-clerodane diterpenoids (1-11) including the new analogues 1, 2, and 10, and 3',5,6,7-tetrahydroxy-4'-methoxyflavone (12) were isolated from the aerial parts of Salvia polystachya. Polystachyne G (1) and 15-epi-polystachyne G (2) were isolated as an epimeric mixture, containing a 5-hydroxyfuran-2(5H)-one unit in the side chain at C-12 of the neo-clerodane framework. Polystachyne H (10) contains a 1(10),2-diene moiety and a tertiary C-4 hydroxy group. The structures of these compounds were established by analysis of their NMR spectroscopic and MS spectrometric data. The absolute configurations of compounds 3, 4, and 10 were determined through single-crystal X-ray diffraction analysis. The antibacterial, antifungal, and phytotoxic activities of the diterpenoids were determined. In addition, the stimulatory effect of the expression of extracellular matrix components of nine of the isolates (1-8 and 11) was assayed. Compounds 1-4, 8, and 11 increased the expression of the genes codifying for type I, type III, and type V collagens and for elastin.
