Acridone alkaloids with cytotoxic and antimalarial activities from Zanthoxylum simullans Hance
Chao Wang, Jinfu Wan,1 Zhinan Mei, and Xinzhou Yang
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
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.

In vitro anthelmintic activity of Zanthoxylum simulans essential oil against Haemonchus contortus.
Qi H, Wang WX, Dai JL, Zhu L.
Abstract
The need for new anthelmintic agents with low impact on the environment is becoming urgent. Phytotherapy is an alternative method to control gastrointestinal nematodes in small ruminants. This study aims to determine the composition of Zanthoxylum simulans essential oil (ZSEO) and evaluate the in vitro ovicidal and larvicidal effects of ZSEO on Haemonchus contortus using egg hatch assay, larval development assay (LDA), and larval migration inhibition assay (LMIA). The chemical composition of ZSEO was determined through gas chromatography and mass spectrometry and 94 compounds were identified from the ZSEO. The major constituents of ZSEO were borneol (18.61%), β-elemene (10.87%). ZSEO and borneol both at 40 mg/mL inhibited larval hatching by 100%, with LC50 values of 3.98 and 1.50mg/mL, respectively. The LC50 value of β-elemene was not determined because of its insufficient activity. The results of LDA showed that ZSEO, borneol, and β-elemene all at 40 mg/mL inhibited larval development by 99.8%, 100%, and 55.4%, respectively, and exhibited dose-dependent responses with LC50 values of 4.02, 1.99, and 32.17 mg/mL, respectively. The results of LMIA showed that ZSEO, borneol, and β-elemene all at 40 mg/mL inhibited larval migration by 74.3%, 97.0%, and 53.2%, respectively. ZSEO presented ovicidal and larvicidal activities in vitro. Therefore, Zanthoxylum may be an alternative source of anthelmintic agents to control gastrointestinal nematodes in sheep.
