Continentalic acid from Aralia continentalis shows activity against methicillin-resistant Staphylococcus aureus.[Pubmed:16619343]
Phytother Res. 2006 Jun;20(6):511-4.
In a continuing search for compounds with antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), a chloroform extract of roots of Aralia continentalis was found to contain Continentalic acid (CA, C(20)H(30)O(2)), a diterpenic acid. This compound exhibited potent activity against standard methicillin-susceptible Staphylococcus aureus (MSSA) as well as clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA). It was determined that Continentalic acid had minimum inhibitory concentrations (MICs) of approximately 8-16 microg/mL against S. aureus, including the MSSA and MRSA standard strains. Therefore, the results obtained in this study suggest that Continentalic acid might have potential as an adjunct in the treatment of antibiotic-resistant bacteria.
Ultra-performance convergence chromatography for the quantitative determination of bioactive compounds in Aralia continentalis Kitagawa as quality control markers.[Pubmed:28306202]
J Sep Sci. 2017 May;40(9):2071-2079.
A rapid ultra-performance convergence chromatography method was developed for the quantitative determination of bioactive compounds in Aralia continentalis as quality control markers. Quantitative analysis indicated the presence of two major bioactive compounds: diterpenoid acids Continentalic acid and kaurenoic acid. Using a Torus 1-aminoanthracene column, Continentalic acid and kaurenoic acid were separated in less than 8 min. The method was validated with respect to precision, accuracy, and linearity according to the International Conference on Harmonization guidelines. The optimized method exhibited a good linear correlation (r(2) > 0.996), excellent precision (RSD < 1.0%), and acceptable recoveries (99.97-100.26%). Limits of detection for Continentalic acid and kaurenoic acid were 0.068 and 0.097 mug/mL, respectively, while their corresponding limits of quantitation were 0.207 and 0.295 mug/mL. The system performance of ultra-performance convergence chromatography was compared with that of conventional high-performance liquid chromatography with respect to analysis time and efficiency. The proposed method was found to be reliable and convenient for the quantitative analysis of Continentalic acid and kaurenoic acid in A. continentalis from South Korea and A. pubescens from China. This study is expected to serve as a guideline for the quality control of Aralia continentalis.
In vitro Cytotoxicity of Methanol Extract from Aerial Parts of Aralia cachemirica and Purified Continentalic Acid.[Pubmed:26997711]
Indian J Pharm Sci. 2015 Nov-Dec;77(6):792-5.
The present study was designed to evaluate the in vitro cytotoxic effect of methanol extract of aerial parts including stems, leaves and twigs of Aralia cachemirica and purified Continentalic acid isolated from this extract against a panel of human cancer cell lines of varied tissues. Percentage of growth inhibition was evaluated by sulphorhodamine B assay. Purified Continentalic acid showed moderate cytotoxicity against all the cell lines used. In contrast, the extract exhibited significant concentration dependant cytotoxicity against A-549 (lung), THP-1 (leukemia) and MCF-7 (breast) cell lines. This work highlights cytotoxic potential of this extract, which can further be explored for different constituents for their possible use autonomously or in combined manner in cancer therapy. The detailed analysis of their cytotoxicity has been presented in this paper.
Continentalic acid from Aralia continentalis induces growth inhibition and apoptosis in HepG2 cells.[Pubmed:18806961]
Arch Pharm Res. 2008 Sep;31(9):1172-8.
In this study, we investigated the effects of Continentalic acid (CA, (-)-pimara-8(14), 15-diene-19-oic acid), a diterpenic acid, isolated from Aralia continentalis, on the proliferation and apoptosis induction of HepG2 cells. In 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, the inhibitory effect became gradually stronger with the passage of time, 24, 48 and 72 h after treatment with CA, and the most significant effect was observed at 72 h. CA treatment for 72 h induced DNA fragmentation in a dose-dependent manner. Furthermore, flow cytometric analysis of HepG2 cells exposed to CA showed that apoptotic cells increased in a dose-dependent manner. The induction of apoptosis in HepG2 cells by CA was mediated through the activation of caspase-3, Bak, and Bax, and then through the cleavage of peroxisome proliferator-activated receptor (PARP) and the down-regulation of Bcl-2. These results demonstrate that CA efficiently induces apoptosis and is a good candidate for further evaluation as an effective chemotherapeutic agent.
Anti-inflammatory activity of the constituents of the roots of Aralia continentalis.[Pubmed:19784580]
Arch Pharm Res. 2009 Sep;32(9):1237-43.
To assess the anti-inflammatory activity of the constituents of the roots of Aralia continentalis, ent-pimara-8(14),15-diene-19-oic acid (Continentalic acid, pimaradienoic acid, compound I), 7beta-hydroxy-ent-pimara-8(14),15-diene-19-oic acid (compound II), 7-oxo-ent-pimara-8(14),15-diene-19-oic acid (compound III), 15alpha,16alpha-epoxy-17-hydroxy-ent-kauran-19-oic acid (compound IV) and ent-kaura-16-en-19-oic acid (kaurenoic acid, compound V), their inhibitory effects against cyclooxygenase-2 (COX-2)-catalyzed PGE(2) and inducible nitric oxide synthase (iNOS)-catalyzed NO production by lipopolysaccharide-treated RAW 264.7 cells were examined. Among the compounds tested, compound III and V moderately inhibited NO production. In addition, compound III weakly inhibited PGE2 production, while treatment with compounds II and IV at concentrations of up to 100 microM had no significant effects. Conversely, compound I only weakly inhibited PGE2 and NO production. To elucidate the mechanism by which these changes occurred, the iNOS down-regulating capacity of compound III was investigated. Western blot analysis and an electrophoretic mobility shift assay demonstrated that compound III weakly inhibited COX-2 and iNOS expression at 50-100 microM, and inhibited NF-kappaB activation. When in vivo anti-inflammatory activities of compounds I, III and V were examined, intraperitoneal injection of 4-100 mg/kg of compound I and V significantly inhibited carrageenan-induced paw edema in mice, whereas compound III did not. Taken together, the results of this study suggest that some constituents of A. continentalis, especially compounds I, III and V, exert significant anti-inflammatory activity, which suggests that these constituents contribute, at least in part, to the anti-inflammatory action of the roots of A. continentalis.
