Abstract
Context: Zanthoxylum armatum (Rutaceae) fruit, bark and leaves are used for various conditions of ailments in traditional systems of medicine since ancient times. Aims: This study is designed to lay down the various pharmacognostic and phytochemical standards which will be helpful to ensure the purity, safety, and efficacy of this medicinal plant. Materials and Methods: Various methods including macroscopic, microscopic, physicochemical, and phytochemical methods were applied to determine the diagnostic features for the identification and standardization of intact and powdered drug of Z. armatum leaf, fruit, and bark. Results: The shape, size, color, odor, surface characteristics were determined for the intact drug and powdered materials of leaf, bark and fruit of Z. armatum. Light and electron microscope images of cross-section of leaf and powdered microscopy revealed useful diagnostic features. Histochemical, phytochemical, physicochemical including fluorescence analysis of powdered drug proved useful to differentiate the powdered drug material. High performance liquid chromatography analysis showed the presence of important phytoconstituents such as gallic acid and rutin. Conclusion: The data generated from this study would be of help in the authentication of various parts of Z. armatum, an important constituent of various herbal drug formulations. The qualitative and quantitative microscopic features would prove useful for laying down pharmacopoeial standards. Morphology as well as various pharmacognostic aspects of different parts of the plant were studied and have been described here along with phytochemical, physicochemical studies, which will help in authentication and quality control.

Abstract
Phytochemical investigation of the ethanol extract from the roots of Toddalia asiatica resulted in the isolation of eight new alkaloids, 8-methoxynorchelerythrine (1), 11-demethylrhoifoline B (2), 8-methoxynitidine (3), 8-acetylnorchelerythrine (4), 8,9,10,12-tetramethoxynorchelerythrine (5), isointegriamide (6), 1-demethyl dicentrinone (7), and 11-hydroxy-10-methoxy-(2,3)-methylenedioxytetrahydroprotoberberine (8), together with 10 known alkaloids. Their structures were determined on the basis of spectroscopic analyses, including 1D-NMR, 2D-NMR, and HR-ESI-MS. The isolated components were evaluated in vitro for cytotoxic activities against eight tumor cell lines, antimicrobial activities against two Gram-positive bacteria and five Gram-negative bacteria, and antifungal activities against five pathogens. Benzo[c]phenanthridine and secobenzo[c]phenantridine alkaloids exhibited significant cytotoxic, antimicrobial and antifungal properties.

Abstract
Background: Zanthoxylum simullans Hance is a popular natural spice belonging to the Rutaceae family and it is one of the common prescribed herbs in traditional Chinese medicine. Materials and Methods: The chemical constituents were mainly isolated and purified by silica gel column chromatography and semi-preparative High Performance Liquid Chromatography. Their structures were identified by comparing the spectral data with those reported in the literature. Cytotoxic activities for the isolated acridone alkaloids were evaluated against two prostate cancer cell lines PC-3M and Lymph Node Carcinoma of Prostate (LNCaP), and their antimalarial activities were tested against two different strains of the parasite Plasmodium falciparum 3D7, and Dd2. Results: The root bark MeOH extract of Z. simullans Hance afforded β-sitosterol, 4-methoxy benzoic acid, daucosterol, and five acridone alkaloids, normelicopidine, normelicopine, melicopine, melicopidine, and melicopicine. All five acridone alkaloids were isolated from this plant for the first time and exhibited certain cytotoxic and antimalarial activities in vitro. Conclusion: Normelicopidine was the most active against PC-3M, LNCaP and Dd2 with IC50 values of 12.5, 21.1, and 18.9 ug/mL respectively.

Abstract
Pyrano[3,2- c]pyridone and pyrano[3,2- c]quinolone structural motifs are commonly found in alkaloids manifesting diverse biological activities. As part of a program aimed at structural simplification of bioactive natural products utilizing multicomponent synthetic processes, we developed compound libraries based on these privileged heterocyclic scaffolds. The selected library members display low nanomolar antiproliferative activity and induce apoptosis in human cancer cell lines. Mechanistic studies reveal that these compounds induce cell cycle arrest in the G2/M phase and block in vitro tubulin polymerization. Because of the successful clinical use of microtubule-targeting agents, these heterocyclic libraries are expected to provide promising new leads in anticancer drug design.

Abstract
Three polyketide compounds, surinone A, surinone B, surinone C and one acylresorcinol, suranone, along with thirty known compounds, were isolated from the whole plant of Peperomia sui. Their structures were elucidated from spectral analysis. Several compounds showed cytotoxic activity against HONE-1 and NUGC-3 cell lines in vitro.

Abstract
A pyrrole alkaloid, pyrrolezanthine [5-hydroxymethyl-1-[2-(4-hydroxyphenyl)-ethyl]-1H-pyrrole-2-carbaldehyde]; a lignan, (-)-simulanol [4- [3-hydroxymethyl-5-((E)-3-hydroxypropenyl)-7-methoxy-2,3-dihydrobenzofuran-2-yl]-2,6-dimethoxy-phenol] and a monocyclic gamma-pyrone, zanthopyranone [3,5-dimethoxy-2-methyl-pyran-4-one], together with 28 known compounds were isolated from the stem wood of Formosan Zanthoxylum simulans. Their structures were determined through spectral analyses. Among the isolates, 11 compounds showed anti-platelet aggregation activity in vitro.

Abstract
A total of 11 methanol extracts obtained from four different Nepalese Zanthoxylum species were screened for their antiproliferative activity against the growth of human keratinocytes (HaCaT cells). The extract obtained from Z. armatum barks was highly active with an IC50 value of 11 micrograms/mL. Also, the extracts obtained from Z. oxyphyllum barks and roots with IC50 values of 53 and 57 micrograms/mL, respectively, showed potent activity. Their antiproliferative activity was not due to cytotoxic effects on cell membranes, as documented by the activity of lactate dehydrogenase released from the cytoplasm of keratinocytes, which did not exceed that of the control value. Rather, they also protected against radical-induced damage to model membranes stimulated with 2,2'-azo-bis(2-amidinopropane) dihydrochloride.
