ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents isolated from the whole plant of Aconitum tanguticum.</p><p><b>METHOD</b>Chemical constituents were isolated and purified from the title plant by using a combination of various chromatographic techniques including column chromatography over silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were elucidated by spectroscopic techniques including 1H-NMR, 13C-NMR, 2D-NMR, and ESI-MS.</p><p><b>RESULT</b>Seven compounds were isolated from this plant and their structures were identified as kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1-->6)-beta-D-galactopyranoside]-7-O-alpha-L-rhamnopyrano-side (1), kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside]-7-O-alpha-L-rhamnopyranoside (2), kaempferol 7-O-alpha-L-rhamnopyranoside (3), gentiopieroside (4), vomifoliol-9-O-beta-D-glucopyranoside (5), dihydrovomifoliol-9-O-beta-D-glucopyranoside (6) and 3,4-dihydroxyphenyl alcohol-beta-D-glucopyranoside (7).</p><p><b>CONCLUSION</b>All the compounds were isolated from this plant for the first time.</p>

ABSTRACT

Objective To establish a method for measuring serum content of gentiopicroside in Beagle dogs and to explore its internal pharmacokinetic features. Methods The rapid and sensitive HPLC method was adopted as external standard. After intravenous injection of gentiopicroside, serum samples of the Beagle were collected and measured on C18 reverse-phase chromatographic column after liquid -liquid extraction. Results The linear range of gentiopicroside was 0.1343~687.375 ?g?mL-1(r2=0.99993). The recovery was within 81.15 %~97.99 %. The limit of detection (LOD) was 0.1343 ?g?mL-1. Conclusion The pharmacokinetic process of gentiopicroside can be described as one-compartment model with intravenous injection , t1/2 = 1.1324 h, Ke = 0.5811 h-1, V= 0.5316 L?kg-1, CL = 0.3274 L?kg-1?h-1. This indicates that gentiopicroside can be quickly distributed and eliminated and is not liable to be accumulated in the body.

ABSTRACT

AIM: To establish an HPLC method of determining paeonol and cinnamaldehyde in Jiarong Tablet. METHODS: Column:Kromasil C_(18)(200 mm?4.6 mm I.D,5 ?m);mobile phase:MeOH-H_2O(65∶35);detection wavelength was at 288 nm;flow rate was 1.0 mL/min. RESULTS: The calibration curve showed a good linea-rity within the ranges of 0.003 6830.018 412 ?g for cinnamaldehyde,0.097 92-0.489 6 ?g for paeonol.(CONCLUSION:)The method is accurate and can be used for the quality control of Jiarong Tablet.
