黄连不同生长期小檗碱含量的变化 总被引:4,自引:0,他引:4
黄连通常栽培在海拔1500米左右的山地。一般生长7~8年后采挖。为了发展黄连生产,汉中地区开展了低海拔(600米~1100米)栽培黄连试验,并已推广生产,提供商品。我们对该区生长在海拔600米和1100米两处的黄连,分别按不同生长年限和一年中不同月份进行小檗碱含量测定,以探求小檗碱在黄连不同生长期中的变化规律,为确定黄连最适收获期提供依据。 相似文献

目的为了提高岩黄连悬浮培养细胞中生物碱的产量。方法以不同浓度黑曲霉诱导子处理岩黄连悬浮培养细胞。结果生物碱的产量随着诱导时间的延长迅速提高,到第6天达到最大值;添加50mg/L诱导子时生物碱产量最高,达到89.2mg/L,比时照组高出2.5倍,当诱导子浓度进一步升高时,生物碱产量反而降低;随着诱导子浓度从0mg/L增大到150mg/L,细胞生物量反而逐渐减少。结论黑曲霉诱导子可促进岩黄连细胞中生物碱的合成,最佳诱导子浓度是50mg/L;过高浓度的诱导子并不利于细胞生长和生物碱合成,细胞生物量的减少是导致生物碱产量下降的一个重要原因。该处理提供了一种简单有效的方法提高岩黄连细胞培养中生物碱的产量。 相似文献

Cassia occidentalis L. (Kasaundi) is a widely used medicinal plant. Earlier, we have shown that it possesses antimutagenic activity against benzo[a]pyrene (BaP) and cyclophosphamide (CP)-induced mutagenicity in mice. In this study, we investigated if this plant could also provide protection against CP-induced immunosuppression in animal models. Swiss albino male mice were treated per os with the aqueous extract of C. occidentalis (100 mg/kg, body weight (b.w.)) for 14 days. Cyclophosphamide was given intraperitoneally in a single dose of 50 mg/kg b.w. Body weight, relative organ weight, lymphoid organ cellularity, hemagglutination titre (HT), plaque forming cell (PFC) assay and quantitative hemolysis of SRBC (QHS) were studied in these animals. CP, as expected, showed suppressive effects on lymphoid organ weight and cellularity and other parameters of humoral immunity. Plant extract treatment itself produced no toxicity. The administration of plant extract to CP-exposed animals resulted in improved humoral responses. C. occidentalis treatment significantly (P<0.01) enhanced PFC response in CP-treated animals. In QHS assay, also C. occidentalis showed protection in CP-treated animals. Bone marrow cell counts, which were reduced in CP-treated animals, were reversed significantly (p<0.01) to normal levels in CP+ plant extract group animals. In our earlier study, we found that C. occidentalis modulated hepatic drug metabolizing enzymes. It is suggested that by a similar mechanism, it may be influencing the hematotoxic and immunotoxic responses of cyclophosphamide. 相似文献

Inhibitory and inductive effects of Corydalis saxicola Bunting total alkaloids (CSBTA) on cytochrome P450s in rats 下载免费PDF全文

Corydalis saxicola Bunting, a well‐known traditional Chinese medicine in south China, has been widely used for the treatment of various hepatic diseases. Its active ingredients are Corydalis saxicola Bunting total alkaloids (CSBTA), which primarily include dehydrocavidine, palmatine, and berberine. These representative alkaloids could be metabolized by hepatic CYP450s. Hence, it is necessary to investigate the potential influences of CSBTA on CYP450s to explore the possibility of herb–drug interactions. In present study, in vitro inhibition and in vivo induction studies were performed to evaluate the potential effects of CSBTA extract on CYP450s in rats. Inhibition assay illustrated that CSBTA exerted inhibitory effects on CYP1A2 (IC50, 38.08 μg/ml; Ki, 14.3 μg/ml), CYP2D1 (IC50, 20.89 μg/ml; Ki, 9.34 μg/ml), CYP2C6/11 (IC50 for diclofenac and S‐mephenytoin, 56.98 and 31.59 μg/ml; Ki, 39.0 and 23.8 μg/ml), and CYP2B1 (IC50, 48.49 μg/ml; Ki, 36.3 μg/ml) in a noncompetitive manner. Induction study showed CSBTA had obvious inhibitory rather than inductive effects on CYP1A2 and CYP2C6/11. Interestingly, neither inhibition nor induction on CYP3A was observed for CSBTA. In conclusion, CSBTA–drug interactions might occur through CYP450s inhibition, particularly CYP1A and CYP2D. Further studies are still needed to elucidate the underlying mechanisms of inhibition. 相似文献

Inhaled Cissampelos sympodialis Down‐Regulates Airway Allergic Reaction by Reducing Lung CD3+T Cells
Giciane C. Vieira Josenilson F. De Lima Regina C. B. Q. De Figueiredo Sandra R. Mascarenhas Claudio R. Bezerra‐Santos Marcia R. Piuvezam 《Phytotherapy research : PTR》2013,27(6):916-925
Cissampelos sympodialis Eichl. (Menispermaceae) root infusion is used in Northeast Brazil to treat allergic asthma. We have previously shown that oral use of the plant extract reduces eosinophil infiltration into the lung of ovalbumin (OVA)‐ sensitized mice. However, drugs taken by inhalation route to treat asthma achieve better outcomes. Thereby, in this study, we evaluated the inhaled C. sympodialis alcoholic extract as a therapeutic treatment in OVA‐sensitized BALB/c mice. The parameters which were analyzed consisted of leukocyte recruitment to the airway cavity, tissue remodeling and cell profile. The inhaled extract inhibited mainly eosinophil recruitment to the pleural cavity, bronchoalveolar lavage and peripheral blood. This treatment reduced the OVA‐specific IgE serum titer and leukocyte infiltration in the peribronchiolar and pulmonary perivascular areas as well as mucus production. In addition, we also tested isolated alkaloids from the plant extract. The flow cytometric analysis showed that methylwarifteine (MW) and, mainly, the inhaled extract reduced the number of CD3+T cells and eosinophil‐like cells. Therefore, inhaled C. sympodialis extract and MW lead to down‐regulation of inflammatory cell infiltration with remarkable decrease in the number of T cells in an experimental model of respiratory allergy, suggesting that the plant can be delivered via inhalation route to treat allergic asthma.
