OBJECTIVE To compare the chemical differences in 4 commercial specifications of Scutellaria Radix, research the affection of decayed central xylem part on the crude drug's chemical composition and provide scientific data for production, processing, sale and clinical applications of Scutellariae Radix. METHOD Macroscopical identification method was used for observation of different specifications of Scutellariae Radix, including Qinwang, Tiaoqin both in 1st class and 2nd class and inferior samples. HPLC fingerprint method was used to analyze chemically the decayed central xylem part and non-decayed part as well as complete sample, and the results were described by the relative peak area. RESULT The morphological characteristics of 4 specifications are greatly different from one another mainly in root diameters, root lengths and the proportions of decayed central xylem part in the root, and so the authors classified Qinwang and Tiaoqin in 1st class as Kuqin for all samples of them which have decayed central xylem; and classified Tiaoqin in 2nd class and the inferior samples as Ziqin, for having little decayed central xylem. The 4 specifications collected from the same producing area have similar HPLC fingerprint profile to one another, while they are different in relative peak area. The peak area ratios of aglycone to their glucuronide (baicalein/baicalin, wogonin/wogonoside, oroxylin A/oroxylin A-7-O-glucuronide) from Kuqin were significantly higher than those of Ziqin. The total area of the peaks in HPLC fingerprint chromatographs of decayed central xylem part were quite lower than that of non-decayed part, whereas peak areas of the characteristic peaks and the 3 peak area ratios of decayed central xylem were significantly higher than those of non-decayed part which could be used as characteristic parameters to distinguish Kuqin and Ziqin. CONCLUSION Four commercial specifications of Scutellariae Radix can be classified as Kuqin and Ziqin respectively according to morphological characteristics and the proportions of decayed central xylem part in the root. The chemical characteristics of Kuqin and Ziqin are different from each other, so it's worth clarifying the similarities and differences of Kuqin and Ziqin in future. The result in this research can be used as references for identification and quality control of Scutellariae Radix specifications, and investigation on effective components of Kuqin and Ziqin.
目的比较4种市售黄芩药材的化学成分差异，研究中央木质部腐烂对黄芩药材化学成分的影响，为黄芩的生产、加工、销售和临床应用提供科学依据。方法采用宏观鉴别方法，对黄芩、调芩等黄芩药材的一等品、二等品及劣品进行宏观鉴别。采用高效液相色谱指纹图谱法对腐烂的中央木质部和未腐烂的部分以及完整样品进行化学分析，并用相对峰面积来描述结果。结果4个品种的形态特征差异较大，主要表现在根径、根长和中心木质部腐烂部位在根中的比例等方面，因此对中心木质部腐烂的品种均将秦王和调琴归为第一类苦琴;因中心木质部腐烂较少，将跳琴归为第二类，次类归为紫琴。同一产地4种药材的HPLC指纹图谱相似，但相对峰面积不同。苦芩苷元与葡萄糖苷(黄芩苷/黄芩苷、枸杞苷/枸杞苷、oroxylin A/oroxylin A-7- o -glucuronide)的峰面积比显著高于紫芹。中央木质部腐烂的HPLC指纹图谱中各峰的总面积明显小于未腐烂的木质部，而中央木质部的特征峰的峰面积和3个峰面积比明显高于未腐烂的木质部，可以作为区分库琴和紫琴的特征参数。结论根据黄芩的形态特征和根部中心木质部腐烂的比例，4种商品规格的黄芩可分别归类为苦芩和紫芩。Kuqin和Ziqin的化学特征各不相同，因此在今后澄清Kuqin和Ziqin的异同是值得的。本研究结果可为黄芩药材的鉴别和质量控制以及苦芩、紫芩有效成分的研究提供参考。

OBJECTIVE: To observe the difference between the combination therapy of alpha-interferon (IFN-alpha) therapy Yixuesheng Capsule and the monotherapy of IFN-alpha in treatment of chronic hepatitis B. METHOD: A total of 288 patients with HBeAg-positive chronic hepatitis B proven by liver biopsy were included in this study. During the individualized therapy, they received hypodermic injection of IFN-alpha 1b, with 5 MU x time(-1) and three times x w(-1). Of them, 125 patients received combination therapy with Yixuesheng Capsule for three months, with 1.0 g/time and three times/d; and 163 patients received only IFN-alpha 1b (the IFN-alpha monotherapy group). After the course of therapy, all patients were followed up for at least 24 months. The intention-to-treat analysis was adopted for statistic analysis. RESULT: The two groups showed no statistical significance by gender, age, liver necroinflammation grading, liver fibrosis staging, serum ALT levels, serum HBV DNA levels and IFN-alpha therapy course. The whole course and the 24-month follow-up visit cover all of 112 patients in the combination treatment group and 141 cases in the IFN-alpha monotherapy group. The response rates of the combination treatment group and the IFN-alpha monotherapy group were 48.0% (60/125) and 35.0% (57/163) (x = 4.980, P = 0.026) at the end of treatment, respectively, 45.6% (57/125) and 33.1% (54/163) (x2 = 4.645, P =0.031) at the end of 12-month-follow-up period, respectively, and 38.4% (48/125) and 32.5% (53/163) (x2 = 1.076, P = 0.300) at the end of 24-month follow-up period, respectively. CONCLUSION: The combination treatment with IFN-alpha and Yixuesheng Capsule shows a slightly better sustained efficacy on HBeAg-positive chronic hepatitis B patients compared with IFN-alpha monotherapy.

: Baicalein, a flavonoid compound extracted from dried roots of traditional Chinese medicine Scutellaria baicalensis, has been widely applied as an antioxidant and anti-inflammatory agent. With continuous studies on its mechanisms, recent findings suggest that baicalein has some effect on neuroprotection and improvement of clinical symptoms in neurodegenerative diseases such as Parkinson's disease. Recent studies showed that its neuroprotective efficacy is closely related to such functions as antiinflammatory, antioxidative stress, protecting chondriosome, inhibiting glutamate neurotoxicity, promoting nerve growth and inhibiting alpha-synuclein protein-aggregate activities. The aim of this article is to summarize the neuroprotective effects of baicalein in Parkinson's disease.

OBJECTIVE To determine the structures and contents of the volatile components of flowers of Fritillaria thunbergii, and investigate the effects of operation modes on its volatile components. METHOD The volatile oils were first obtained by the hydrodistillation assay and then submitted to gas chromatography-time-of flight mass spectrometry (GC-TOF-MS) analysis. RESULT More than 60 peaks were resolved, and 39 of which were identified quantitatively and qualitatively based on high-resolution spectra and compounds library screening. Among these identified components, the octadecatrienoic acid methyl esters were major components in the unprocessed flowers, while some aromatic aldehydes and ketones, such as benzeneacetaldehyde and 1-(2-hydroxy-5-methylphenyl)-ethanone, were prominent components in the flowers both dried in the fluidized bed and in shadow. In addition, the flowers dried in the fluidized bed were more fragrant than other flowers. CONCLUSION The component and contents closely related to their processing mode, and the fluided bed drying may be a best choice to process the flowers of F. thunbergii.

During Pre-Qin and Qin-Han Dynasty, the origin production places of Huanglian were small and limited. During Weijin-Nanbei Dynasty, the origin production places of Huanglian grew in number gradually. During Sui-Tang and Song-Yuan Dynasty, the origin production places of Huanglian were enlarged quickly. During Ming and Qing Dynasty, the origin production places of Huanglian were expended small-size. The origin production places of Huanglian were enlarged because its functions and demands added and planting-technology skills developed.

OBJECTIVE To search for low-molecular-weight neuritogenic compounds from the traditional Chinese medicine (TCM). METHOD An extract library of TCM was prepared. Targeted isolation guided by biological screening led to the discovery of compound 1, and its structure was elucidated by analysis of spectroscopic methods and comparison of spectroscopic data with these reported from the literature. RESULT A neuritogenic compound 1, 3-O-beta-D-glucopyranosyl-22E, 24R-5alpha, 8alpha-epidioxyergosta-6, 22-diene, was isolated and identified from the methanol extract of T. fuciformis. This compound showed a significant neuritogenic activity against PC12 cells at 3 micromol x L(-1)). CONCLUSION Methonal extract of T. fuciformis and targeted compound 1 both showed significant neuritogenic activity against PC12 cells. These results suggested that the extract and compound 1 might be used to prevent and treat neurodegenerative disease such as Alzheimer's disease.
