Discovery and molecular elucidation of the anti-influenza material basis of Banlangen granules based on biological activities and ultra-high performance liquid chromatography coupled with quadrupole-orbitrap mass spectrometry.

Ethnopharmacological Relevance: Traditional Chinese medicine (TCM) has a wide range of applications, including human healthcare-associated treatments and bioactive compound discovery. However, complex chemical systems present a significant challenge for chemical-material-based research and quality control. For instance, Banlangen (BLG) granules is a well-acknowledged TCM preparation widely used in clinical treatment of virus infection.

Desorption Electrospray Ionization Mass Spectrometry Imaging Illustrates the Quality Characters of Isatidis Radix.

For a long history, herbal medicines have made significant contributions to human health all around the world. However, the exploration of an effective approach to illustrate their inner quality remains a challenge. So, it is imperative to develop new methods and technologies to characterize and identify quality markers of herbal medicines.

Microscopic Mass Spectrometry Imaging Reveals the Distribution of Phytochemicals in the Dried Root of .

The dried root of L. (Brassicaceae) is one of the most popular traditional Chinese medicines with well-recognized prevention and treatment effects against viral infections. Above 300 components have been isolated from this herb, but their spatial distribution in the root tissue remains unknown.

Micro-morphological identification study on Cordyceps sinensis (Berk.) Sacc. and its adulterants based on stereo microscope and desktop scanning electron microscope.

The Chinese Materia Medica, Cordyceps sinensis (called "Dongchongxiacao" in Chinese), used as a tonic for nearly 600 years by Traditional Chinese Medicine, which has been recorded by Chinese Pharmacopoeia. This drug is rare and precious, which in turn lead to the emergence of adulterants derived from the same genus of Cordyceps. The adulterants which can be commonly found in the market are Cordyceps gunnii (called "Gunichongcao" in Chinese), Cordyceps liangshanensis (called "Liangshanchongcao" in Chinese), and Cordyceps gracilis (called "Xinjiangchongcao" in Chinese).

Antiviral activity of Isatidis Radix derived glucosinolate isomers and their breakdown products against influenza A in vitro/ovo and mechanism of action.

Ethnopharmacological Relevance: Isatidis Radix, the sun-dried roots of Isatis indigotica Fortune ex Lindl., is one of the most usually used traditional Chinese medicines. For centuries, the herb has been employed in clinical practice for treatment of virus infection and inflammation.

[Expert consensus on prescription comment of Chinese traditional patent medicine for promoting the rational use of drugs in Beijing].

With the growth of number of Chinese patent medicines and clinical use, the rational use of Chinese medicine is becoming more and more serious. Due to the complexity of Chinese medicine theory and the uncertainty of clinical application, the prescription review of Chinese patent medicine always relied on experience in their respective, leading to the uncontrolled of clinical rational use. According to the traditional Chinese medicine (TCM) theory and characteristics of the unique clinical therapeutics, based on the practice experience and expertise comments, our paper formed the expert consensus on the prescription review of Chinese traditional patent medicine for promoting the rational use of drugs in Beijing.

[Guideline principle and technical requirement for preparing traditional Chinese medicine reference drug].

Traditional Chinese medicine (TCM) reference drug is a new form of TCM standard reference substance. The purpose of this guideline is to guide the establishment of the reference drug and standardize its investigation and application in national drug standards. Definition of TCM reference drug was specified and relating guideline and technical requirement were introduced in this paper.

[Application of microscopic spectroscopy in quality control of Niuhuang Qingxin pills].

Application of microscopic spectroscopy in quality control of Niuhuang Qingxin pills was discussed. First, microscopic characteristics specified by the statutory standard of Niuhuang Qingxin pills were summarized. Then new identification method was established for Dioscoreae Rhizoma, Saigae Tataricae Cornu, Cinnamomi Cortex and Saposhnikoviae Radix.

[Preliminary investigation on polymorphs of two traditional Chinese medicine reference substances].

Crystal structures of chemical drugs has been being investigated widely. But few attention has been paid to polymorphs-phenomena of active ingredients from Traditional Chinese Medicine(TCM). Taking anhydrous dehydroandrographolide and hydrousprim-O-glucosylcimifugin as example, differences between TCM reference substances (RSs) with different crystal structures were discussed by using microscopy, melting point determination, differential thermal analysis (DTA) and infrared (IR) methods.

Quantitative Analysis of Panax ginseng by FT-NIR Spectroscopy.

Near-infrared spectroscopy (NIRS), a rapid and efficient tool, was used to determine the total amount of nine ginsenosides in Panax ginseng. In the study, the regression models were established using multivariate regression methods with the results from conventional chemical analytical methods as reference values. The multivariate regression methods, partial least squares regression (PLSR) and principal component regression (PCR), were discussed and the PLSR was more suitable.

[Nondestructive identification of the root of mountain cultivation ginseng and growth years by near infrared spectroscopy].

Mountain cultivation ginseng (MCG) and garden cultivation ginseng (GCCG) were identified by near infrared spectroscopy, so were MCG of different growth years. 96 MCG samples of different growth years, including 24 of fifteen years and 72 of ten years, and 177 GCG samples were collected. After the near infrared spectra of these samples were collected, discriminant analysis was used to distinguish MCG and GCG, so was MCG of different years.

Rapid discrimination of Chinese red ginseng and Korean ginseng using an electronic nose coupled with chemometrics.

Red ginseng is a precious and widely used traditional Chinese medicine. At present, Chinese red ginseng and Korean ginseng are both commonly found on the market. To rapidly and nondestructively discriminate between Chinese red ginseng and Korean ginseng, an electronic nose coupled with chemometrics was developed.

Simultaneous determination of ginsenosides and lignans in Sheng-mai injection by ultra-performance liquid chromatography with diode array detection.

An ultra-performance liquid chromatography (UPLC) method with diode array detection was developed for simultaneous analysis of eight ginsenosides (ginsenosides Rg1, Re, Rf, Rb1, Rc, Rb2, Rb3, Rd) and one lignan (schizandrin) in Sheng-mai injection, a traditional Chinese medicine prescription widely used for the treatment of cardiovascular diseases.
