Chemical constituents of Caulophyllum robustum and its antitumor activities / 中草药

Objective To study the chemical constituents of Caulophyllum robustum and its antitumor activities. Methods The chemical constituents were isolated and purified with silica gel column chromatography, dextran gel Sephadex LH-20, and other chromatographic methods. Their structures were determined by physicochemical and spectral analysis. Furthermore, the cytotoxicity of these chemical components against the NSCLC A549 cell line was measured by CCK-8 method. Results Eleven compounds were isolated and identified as collinsogenin (1), hederagenin (2), eechinocystic acid 3-O-α-L-arabinopyranoside (3), magnolamide (4), (-)-magnocurarine (5), columbamine (6), 4,4’-diphenylmethane-bis (methyl) carbamate (7), (-)-8,8’-dimethoxy-L-O-(β-D- glucopyranosyl) secoisolariciresinol (8), asechipuroside A (9), 2-[4-(3-hydroxy-1-propenyl)-2-methoxyphenoxy]-1,3-propanediol (10), and 1-linoleoylglycerol (11). Conclusion Compounds 1-2 and 4-11 are isolated from Caulophyllum robustum genus for the first time. Compounds 1 and 2 show moderate inhibited effect on the proliferation of NSCLC A549 cell line.

Determination of six saponins in Caulophyllum robustum by QAMS / 中草药

Objective: To establish a method of quantitative analysis of multi-components by single-marker (QAMS) for simultaneous determining six saponins in Caulophyllum robustum. Methods: Cauloside G was used as the internal reference standard; The relative correction factors of cauloside H, leonticin D, cauloside D, cauloside B, and cauloside C in C. robustum were calculated. To achieve the QAMS, the contents of indicative saponins were calculated by relative correction factors. At the same time, the external standard method was used to detect the contents of six kinds of ingredients in medicinal materials, and feasibility of QAMS was verified. Results: The relative correction factor had good reproducibility, there were no significant differences among the calculated values of multi-evaluation and measured values of the external standard method. Conclusion: In the absence of reference substance situation, QAMS can be used for the quality evaluation of C. robustum, and the method is accurate and reliable.

Saponin constituents from roots and rhizomes of Caulophyllum robustum / 中草药

Objective: To separate the saponins from the roots and rhizomes of Caulophyllum robustum and determine their chemical structures. Methods: The chemical constituents were isolated by repeated silica gel chromatography, medium pressure column chromatography, and semi-preparative liquid chromatography. Their structures were elucidated by the data of NMR and MS. Results: Ten compounds were isolated from the roots and rhizomes of C. robustum and the structures of compounds 1-10 were identified as echinocystic acid-3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside (1), 3-O-α-L-arabinopyranosylhederagenin-28-O-β-D- glucopyranosyl-(1→6)-β-D-glucopyranoside (2), HN-saponin H (3), ciwujianosides A1 (4), glycoside L-K1 (5), 3-O-β-D- glucopyranosyl-(1→3)-α-L-arabinopyranosyl-hederagenin-28-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-gluco-pyranoside (6), leonticin F (7), 3-O-β-D-glucopyranosyl-(1→3) [β-D-glucopyranosyl-(1→2)] α-L-arabinopyranosyl-echinocystic acid-28-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (8), leonticin A (9), and morroniside (10). Conclusion: Compound 10 is a iridoid. Compounds 1 and 10 are firstly isolated from the plants of Caulophyllum Maxim., compouds 2-9 are isolated from this plant for the first time.

Impacto socioeconómico del Caulophyllum en pacientes con inmadurez cervical / Social and economic impact of Caulophyllum in patients with cervical immaturity

Se realizó un estudio descriptivo y transversal de 1 994 mujeres, ingresadas en el Hospital Ginecoobstétrico Docente "Tamara Bunke Bider", de Santiago de Cuba, desde enero del 2011 hasta diciembre del 2012, con vistas a valorar el tratamiento con Caulophyllum en la maduración cervical y propiciar el trabajo de parto espontáneo antes de las 42 semanas o la respuesta positiva a la inducción, así como la determinación del impacto socioeconómico de este método. En la casuística disminuyeron las inducciones y cesáreas, a la vez que se incrementaron los partos eutócicos, lo cual garantizó una mejor calidad en la atención a las pacientes, con menos gastos de recursos materiales y capital humano, así como también con reducción de los costos hospitalarios.

A descriptive and cross sectional study of 1 994 women, admitted in "Tamara Bunke Bider" Teaching Gynecological and Obstetrical Hospital in Santiago de Cuba was carried out from January, 2011 to December, 2012, with the aim of evaluating the treatment with Caulophyllum in the cervical maturation and to propitiate the spontaneous childbirth before the 42 weeks or the positive response to the induction, as well as the determination of the socioeconomic impact of this method. The inductions and caesarean sections decreased in the case material, at the same time eutocic childbirths were increased, which guaranteed a better quality in the care to these patients, with less expenses of material resources and human capital, as well as with reduction of the hospital costs.
