Complete Genome Sequence of HKU8 Isolated from Human Blood.

Members of the genus are strongly associated with human diseases. We present here the complete genome sequence of HKU8, which consists of one circular chromosome. The strain characteristically contains various genes encoding for enzymes involved in arylamidase utilization.

[Simultaneous determination of 5 kinds of alkaloids in Kechuanning tablets by SPE-UPLC under different UV-vis wavelength].

The paper is to establish a method for simultaneous determination of 5 kinds of alkaloids in ephedra and poppy which are in Kechuanning tablets. Solid-phase extraction (SPE) was adopted in pretreatment, and a UPLC method with 2 different wavelengths had been developed: 210 nm for the detection of morphine, codeine phosphate, ephedrine hydrochloride and pseudoephedrine hydrochloride, and 251 nm for papaverine hydrochloride. The column used was Acquity UPLC BEH C18 (100 mm x 2.

[Determination of nucleosides in siweilingzhi mixture by HPCE].

Objective: To establish a method for determining nucleosides (adenoside and guanoside) in Siweilingzhi Mixture by HPCE.

Method: Adenoside and guanoside were separated within 25 min using an 20 mmol.L-1 borate buffer with 30 mmol.

[Quantitative analysis of organophosphorous pesticide residues in Chinese drugs].

This paper reports the GC determination of 13 organophosphorous pesticides in Chinese drugs Flos Ionicerae and Moluodan etc by the present method of Japan for determining pesticide residues. The results suggest that the determined samples do not contain the above said 13 organophosphorous pesticides.

[Quantitative analysis of organochlorine pesticide residues in Chinese drugs].

This paper reports the GC determination of 20 organochlorine pesticides in Chinese drugs Flos Ionicerae and Moluodan etc by the present method of Japan for determinaing pesticide residues. The results suggest that except Folium Isatidis, Radix Codonopsis and Sanqi Pian all accord with the for provisions pesticide residues in Japanese foodstuffs.

[Quality of rhizoma Anemarrhenae grown for different periods of time and gathered in different seasons].

The experimental results have shown that except the stem and leaves all kinds of Rhizoma Anemarrhenae and all parts of the herb contain sarsasapogenin, but the contents are different. Furthermore, the root and peel of Rhizoma Anemarrhenae may be used as drug instead of Rhizoma Anemarrhenae.

[Quality standards for qingwei huanglian pills].

In the paper systematic studies on quality standards for Qingwei Huanglian Pills are reported, along with the TLC identification of Gardenia jasminoides, Scutellaria baicalensis and Anemarrhena asphodeloides and the quantitative determination of berberine in Coptis chinensis and Phellodendron chinese by TLC densitometric method. To simplify the operation, the same solvent was used for both the identification and determination. The quantitative method is simple, sensitive, reproducible and accurate.

[Quality standard of kaixiong shunqi pills].

This paper adds TLC identification of binglang and other three cruds drugs to the quality control of kakxiong shunqi pills incorporated in Chinese Pharmacopoeia. The contents of magnolol and honokinol were determined by TLC scanning. The method is simple, rapid accurate, and useful in controlling the quality of kaixiong shunqi pills.

[Determination of glycyrrhetinic acid in radix Glycyrrhizae by TLC densitometry].

A TLC densitometric method for the determination of glycyrrhetinic acid in Radix Glycyrrhizae is described. The method is accurate, sensitive and simple. The recovery of glycyrrhetinic acid is 98.

[Determination of tangshenoside I in Codonopsis pilosula Nannf. by TLC-UV spectrophotometric method].

A method of thin layer chromatographic separation and ultraviolet spectrophotometric determination of tangshenoside I in Codonopsis pilosula is described. A comparison of the contents in various samples is made. The contents of tangshenoside I in frosted sample have been found to be twice as much as in normal drug.

[Chemical constituents of Codonopsis pilosula Nannf].

An exclusive constituent has been isolated from the water soluble parts of root of Codonopsis pilosula for the first time. The constituent has been confirmed to be tangshenosid I.
