The aromatics fractions of crude oil and source rocks have been analyzed by high performance liquid chromatography (HPLC) using reversed phase column ODS-C18 and gradient elution from methanol and water ( 80:20 ) to methanol(100% ) at 70 min. A variable wavelength UV detector was used in this work. The sample mixed of 12 types for different benzene rings aromatics (naphthalene, biphenyl, phenanthrene, anthracene, f luoranthene, pyrene, chrysene, benzo ( a ) anthracene, perylene, benzo ( a ) pyrene, coronene and pentacene ) has been identified at different UV wavelength (254 nm, 285 nm, 300 nm, and 320 nm ) . The results identified showed that each type has higher absorption and especically, lowerbenzene rinsg aromatics have obvious absorption at UV 254 nm; that coronene has obviou high absorption, chrysene and benzene(a)anthracene have still higher absorption, but other aromatics have lower absorption, at uv 285nm) that coronene has still obvious high absorption, pyrene and chrysene and perylene have lower and other aromatics have very low absorption at 300nm; that each type has very low absorption at 320nm. That means the lower benzene ring aromatics have high absorption at 254nm; the higher benzene ring aromatics have high absorption at 285nm or 300nm and at 254nm higher ring aromatics have absorption, too. So that the aromatics compositions of crude oil and source rocks can be analyzed by HPLC of different UV wavelength detections.

An HPLC method for the determination of tetramethylpyrazine in serum and application of this method to tetramethylpyrazine deposition studies in human body were described. Tetramethylpyrazine was extracted from alkalinized serum with dichloromethane using methaqualone as internal standard. A RP μ-Bondapak-C_(18) (10μm) column fitted with a variable-wavelength UV spectrophotometer operated at 280 nm was used. The mobile phase was methanol-water (58: 42). The detection limit of the method was 0.0174 μg/ml serum. Assay linearity was shown over the range of 0.0291~5.816 μg/ml serum with a regression coefficient of 0.9999. The extraction recovery was 99.84% and no interference was found from endogenous compounds, metabolites of parent drug or other commonly used drugs. For the serum concentration following oral administration of tetramethylpyrazine capsules to healthy volunteers (n=6), the best fit was found to be with a two compartment open model. After administration of 174.5 mg dose, the pharmacokinetic parameters were as follows. Tp=0.5102 h, Cmax=3.114 μg/ml, AUC=5.893 mg/L·h, T_(1/2) (Ka)=0.1508 h,T_(1/2)(α)=0.4855 h, T_(1/2)(β)=2.894 h, Cl=15.7 L· h~(-1), V_c=17.70 L, V=66.77 L.The result imply that tetramethylpyrazine is absorbed rapidly, distributedwidely in the body, and also eliminated at a fairly rapid rate.

A high performance liquid chromatography method was used for quantitative determination of albendazole (Alb) and its major metabolites, albendazole sulfoxide (AlbSO) and albendazole sulphone (AlbSP) in plasma of rabbits and mice. A ODS (5μm) column ditted with a variable wavelength UV detector at 292 nm was used for assay, and mebendazole was used as internal standard. The mobile phase used was 48% methanol / H2O (v / v, containing HClO4 0.6 ml·L-1) with a flow rate of 1 ml. min-1. The detectable limitation of Alb or AlbSO in plasma was 5 ng·ml-1, while that of AlbSP was 10 ng·ml-1. The recoveries of Alb, AlbSO and AlbSP by the method were 93.5%, 96.6% and 99.2%, respectively. The results showed that the method is simple, precise and sensitive and is suitable for pharmacokinetic study and microdetermination of the relevant substances present in the tissues.
