RESUMO

The present study aims to investigate the lignans from the flower buds of Magnolia biondii. The isolation and purification of the compounds were performed by column chromatographies on Diaion HP-20, silica gel, and Sephadex LH-20, combined with semi-preparative HPLC. Their structures were elucidated on the basis of spectral data and physiochemical properties. Eighteen compounds were isolated and identified as magnolin (1), epimagnolin (2), eudesmin (3), kobusin (4), aschantin (5), lirioresinol B dimethyl ether (6), pinoresinol monomethy ether (7), (+)-de-O-methylmagnolin (8), isoeucommin A (9), syringaresinol 4-O-ß-D-glucopyranoside (10), phillygenin (11), lariciresinol-4'-O-ß-1-D-glucoside (12), conicaoside (13), (7'S, 8'R)-dihydrodehydrodiconiferylalcohol (14), 7R*, 8S*-dihydrodehydrodiconiferyl alcohol 4-O-ß-D-glucopyranoside (15), 7S, 8R-erythro-7, 9, 9'-trihydroxy-3, 3'-dimethoxy-8-O-4'-neolignan 4-O-ß-D-glucopyranoside (16), 7S, 8R-erythro-4, 9, 9'-trihydroxy-3, 3'-dimethoxy-8-O-4'-neolignan-7-O-ß-D-glucopyranoside (17), and (+)-isolariciresinol (18).

RESUMO

Ranae Oviductus has a high economic and social value, but its adulterants are more numerous, which causes a great confusion to the market. Using DNA bar code technology based on COI sequence for PCR amplification and sequencing of the identified Rana dybowskii, R. chensinensis, R. huanrensis and R. amurensiss, the COI gene database of four species of Rana was established, and comparing the measured sequence with the sequence of GenBank, four kinds of Rana were identified. The MEGA (molecular evolutionary genetics analysis) 7 .0 software was used to calculate the genetic distance of K2P and construct the NJ (neighbor-joining) system cluster tree. The sequence of the four species of Rana measured were clustered into one group with the sequence of the four kinds of Rana downloaded from GenBank, but separated from the two outer groups downloaded from GenBank. The COI gene of the R. dybowskii was likely to have regional differences, however this technique failed to distinguish male and female Rana. The results showed that DNA bar code technology could accurately identify the base of original animal of R. oviductus. It indicates that DNA bar code COI provides a new method for the identification of R. oviductus.

RESUMO

Pulsatilla chinensis f. alba D. K. Zang 1993 is a forma of Pulsatilla chinensis (Bge.) Regel, the root of P. chinensis is traditional Chinese medicine called Pulsatillae radix. The biggest difference between P. chinensis f. alba and P. chinensis is that P. chinensis f. alba sepals is white. The complete chloroplast genome of P. chinensis f. alba was sequenced using the Illumina NovaSeq platform for the first time. The lengths of the genome, large single-copy (LSC), small single-copy (SSC), two inverted repeats (IRs), and GC content were 163,654 bp, 82,355 bp, 19,069 bp, 31,115 bp, and 37.2%, respectively. It had 134 genes, including 90 protein-coding genes, 36 tRNA genes, and eight rRNA genes. The maximum-likelihood tree indicated that P. chinensis f. alba had a closer relationship with P. chinensis. This study would provide a theoretical basis for the further study of Pulsatilla plants genetics phylogenetic research.

RESUMO

In the title hydrated mol-ecular salt, C(11)H(14)N(3)O(+)·Br(-)·H(2)O, the Br(-) anion is split and appears as two independent half-occupied Br(-) anions on twofold rotation axes. The dihedral angle between the phenyl ring and the mean plane of the 2,3-dihydro-1H-pyrazole ring (r.m.s. devation = 0.014 Å) is 62.43 (7)°. In the crystal, the components are connected via O-H⋯Br and N-H⋯O hydrogen bonds to form a one-dimensional polymeric structure propagating along [001].

RESUMO

In the title compound, [Na(C(10)H(9)O(6))(C(10)H(10)O(6))]·0.5C(10)H(8)N(2)·H(2)O, the Na atom is eight-coordinated in an distorted dicapped-octa-hedral geometry by eight O atoms from a 2-(2-carb-oxy-meth-oxy-phen-oxy)acetate (o-BDOAH) anion and a 2,2'-(o-phenyl-enedi-oxy)diacetic acid (o-BDOAH(2)) mol-ecule. The uncoordinated 4,4'-bipyridine mol-ecule is arranged around an inversion center and exhibits rotational disorder. A three-dimensional supra-molecular network is built up in the crystal through O-H⋯O and O-H⋯N hydrogen bonds between the uncoordinated water mol-ecule, the uncoordinated 4,4'-bipyridine mol-ecule and the sodium complex mol-ecule.

RESUMO

Chinese yam (CY), used as both a traditional Chinese medicine and a nutritious food, is an excellent candidate for treating septic cardiomyopathy (SCM). Adenosine, arbutin and allantoin are the major active components in the aqueous extract of CY. The aim of the present study was to interpret the roles of CY, adenosine, arbutin and allantoin in SCM treatment. Firstly, significant physiological indexes were examined to assess the model and treatment effects of CY, adenosine, arbutin and allantoin. Then, a metabolomic approach was utilized to reveal the metabolic disorders in SCM concerning the intervention of CY/adenosine/arbutin/allantoin. The integrated results demonstrated that adenosine, arbutin and allantoin are responsible for the efficacy of CY on SCM treatment by regulating amino acid, arachidonic acid, sphingolipid, glycerophospholipid and glycol metabolism. Moreover, adenosine and/or arbutin could be used as a substitute for CY in treating SCM, and allantoin efficacy was slightly weaker. This integrated metabolomic approach performed excellently in understanding the herbal function and the roles of its components.

RESUMO

A UPLC-QTOF-MS based metabolomics research was conducted to explore potential biomarkers which would increase our understanding of the model and to assess the integral efficacy of Descurainia sophia seeds extract (DS-A). Additionally, DS-A was split into five fractions in descending order of polarity, which were utilized to illustrate the mechanism together. The 26 identified biomarkers were mainly related to disturbances in phenylalanine, tyrosine, tryptophan, purine, arginine, and proline metabolism. Furthermore, heat map, hierarchical cluster analysis (HCA), and correlation network diagram of biomarkers perturbed by modeling were all conducted. The results of heat map and HCA suggested that fat oil fraction could reverse the abnormal metabolism in the model to some extent; meanwhile the metabolic inhibitory effect produced by the other four fractions helped to relieve cardiac load and compensate the insufficient energy supplement induced by the existing heart and lung injury in model rats. Briefly, the split fractions interfered with the model from different aspects and ultimately constituted the overall effects of extract. In conclusion, the metabolomics method, combined with split fractions of extract, is a powerful approach for illustrating pathologic changes of Chinese medicine syndrome and action mechanisms of traditional Chinese medicine.

RESUMO

A sensitive HPLC method was developed for the quantitative determination of isoliquiritin apioside (ILA) and isoliquiritin (IL) in rat plasma. After protein precipitation with acetonitrile, chloroform was used to separate lipid-soluble impurities from the plasma samples and remove acetonitrile. A chromatography was carried out on Diamonsil C18 (150 × 4.6 mm; 5 µm) analytical column, using a mobile phase consisting of water (containing phosphoric acid 0.1%, v/v); acetonitrile (72 : 28, v/v) at a flow rate of 1.0 mL/min. The wavelength-switching technology was performed to determine ILA and IL at 360 nm and wogonoside (internal standard, IS) at 276 nm. The calibration curves of ILA and IL were fairly linear over the concentration ranges of 0.060-3.84 µg/mL (r = 0.9954) and 0.075-4.80 µg/mL (r = 0.9968), respectively. The average extract recoveries of ILA, IL, and IS were all over 80%. The precision and accuracy for all concentrations of quality controls and standards were within 15%. The lower limit of quantification (LLOQ) was 0.060 µg/mL for ILA and 0.075 µg/mL for IL. The method was used in pharmacokinetic study after an oral administration of Zhigancao extract to rats.
