Abstract Four new alkaloid glycosides, zanthonitisides A–D (1-4), together with five known compounds (5–9) were isolated from the aqueous fraction of stems and twigs of Zanthoxylum nitidum (Roxb.) DC. Their structures were determined on the basis of extensive spectroscopic methods, including 1D-, 2D-NMR, MS, and CD data. All isolated compounds were evaluated for their cytotoxic activity against three human cancer cell lines, CT-26, MCF-7, and MKN-45. As results, compound 4 showed significant cytotoxic activity on MKN-45 cancer cell line with IC50 value of 7.4 ± 1.0 μM. Compound 9 exhibited moderate cytotoxic activity on all tested cancer cell lines with an IC50 values ranging from 34.7 to 44.7 μM.

Two novel prenylated benzophenone related meroterpenes, hypatulins A (1) and B (2), were isolated from the leaves of Hypericum patulum. The structures of 1 and 2 were assigned by spectroscopic analysis, chemical conversion, and calculations of the ECD (electron circular dichroism) spectra. Hypatulin A (1) had a unique densely substituted tricyclic octahydro-1,5-methanopentalene core, while hypatulin B (2) possessed a bicyclo[3.2.1]octane moiety. Hypatulin A (1) exhibited antimicrobacterial activ...

Abstract Eight oleanane- type saponins, glomerulosides A–H, were isolated from leaves of Glochidion glomerulatum. All isolated compounds were evaluated for cytotoxic activity on four human cancer cell lines, A-549, HT-29, OVCAR, and MCF-7. Glomerulosides C and E, which contain a benzoyloxy group at C-22, showed significant cytotoxic activities against the A-549, HT-29, and OVCAR cancer cell lines with IC 50 values ranging from 5.9 to 9.8 μM. Glomeruloside A showed cytotoxicity on HT-29 and OVCAR...

Five novel alkaloids, zanthomuurolanine (1), epi-zanthomuurolanine (2), zanthocadinanines A (3) and B (4), and epi-zanthocadinanine B (5), composed of dihydrochelerythrine and a cadinane-type sesquiterpene linked by a methylene bridge, have been isolated from stem bark of Zanthoxylum nitidum. These structures were elucidated by spectroscopic techniques (UV, IR, MS, CD, 1H NMR, 13C NMR, DEPT, COSY, NOESY, HSQC, and HMBC analyses). Single-crystal X-ray diffraction studies confirmed the relative co...

Nitidumpeptins A and B (1 and 2), two novel cyclic hexapeptides, were isolated from the herb Zanthoxylum nitidum var. tomentosum. Their planar structures were elucidated based on NMR and MS spectrometric analysis, and the absolute configurations were determined by the Marfey's method. Structurally, 1 is a unique peptide with a backbone bearing a pyrrolidine-2,5-dione unit, which is the first occurrence moiety specifically in a naturally occurring cyclohexapeptide. The total synthesis of 1 and 2 ...

Aronia melanocarpa, Cornus mas, and Chaenomeles superba leaf extracts contain large amounts of bioactive compounds—mainly polyphenols, which possess many health benefits including anti-cancer properties. Here, we investigate the biological effects of A. melanocarpa, C. mas, and C. superba leaf extracts on the human colon adenocarcinoma cell line Caco-2. The antiproliferative activity of the extracts was measured using the MTT assay. The most cytotoxic extract was C. mas (IC50 = 0.60%). The extra...

Abstract Zanthoxylum nitidum (Roxb.) DC. (ZN) belongs to the genus Zanthoxylum of Rutaceae and has various chemical ingredients and pharmacologic effects. Alkaloids are its main active constituents responsible for diverse pharmacologic effects, such as anti-tumor, anti-bacterial, anti-inflammatory, and analgesic activities. The chemical and pharmacological effects of ZN are well reported, but the in vivo pharmacokinetic profiles of its main active alkaloids are poorly investigated. This study ai...

Abstract Sichuan pepper, commonly used as a food seasoning, possesses unique anti-diabetic properties. This study uses ultra-high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF) to elucidate the chemical profile of Sichuan pepper. Further, an ultra-filtration was coupled with UHPLC-Q-TOF to screen the α-glucosidase inhibitors (AGIs) for the first time. Results confirmed significant variation in the content of hydroxyl-α-sanshool (HA...
