OBJECTIVE To isolate and identify compounds from Picria fel-tarrae in order to utilize it better. METHOD Constituents from Picria fel-tarrae were isolated by several column chromatography and their structures were elucidated on the basis of chemical and spectral analysis. RESULT Six compounds, N-benzoylphenylalanyl-L-phenylalaninol acetate (1),(More)
AIM To investigate the chemical constituents from Picria fel-terrae Lour. METHODS Column chromatography techniques were used to isolate the chemical constituents, physico-chemical constants and spectroscopic analysis were employed for structural elucidation. Results Two triterpenoids named picfeltarraenone I (1) and picfeltarraenin XI (2) were isolated,(More)
OBJECTIVE To determine the content of linarin in Yuye Jiedu granule. METHOD A HPLC method was developed. The chromatographic conditions are as follows Luna C18 column and acetonitrile-0.05 mol x L(-1) phosphate buffer-phosphoric acid (30:70:0.06) as mobil phase, detection wavelenth at 327 nm. RESULT The linear range of linarin was 0.025-0.50 microg. The(More)
In 0.008 mol x L(-1) HCl medium, [AuCl4]- and I- combine to form [AuI4]-. [AuI4]- reacts with berberine (BB) to form (AuI4-BB) association molecule. The molecules aggregate automatically owing to strong hydrophobic and molecular forces. And (AuI4-BB)n association nanoparticles with orange-yellow color were observed. It exhibits a resonance scattering peak(More)
In 0.01 mol x L(-1) HCl medium, red color [PtI6]2- and quinine combine to form association molecule. The molecules aggregate automatically owing to strong hydrophobic and molecular forces. And PtI6-quinine association particles with violet-red color formed. It exhibits three resonance scattering peaks at 310 nm, 400 nm and 610 nm, and a Rayleigh scattering(More)
AIM To study compounds isolated from Picria fel-terrae. METHODS The chemical constituents were separated and purified by column chromatography on silica gel and MCI. Their structures were identified on the basis of spectral data (IR, UV, MS, ID NMR and 2D NMR). RESULTS A new cucurbitacin, along with a known one, were obtained from the 60% EtOH extract(More)
AIM To study the relationship between resonance Rayleigh scattering(RRS) and the formation of association nanoparticle, and to develop a new and sensitive RRS method for the determination of trace berberine (BB). METHODS The association nanoparticle between BB and tetraphenylboron (TPB) was investigated by means of RRS, absorption spectral method and(More)
OBJECTIVE To observe the effects of Naomaitai capsule on the learning and memory abilities and the content of acetylcholine(Ach) in the brain tissue of the model rat. METHOD One vascular dementia(VD) model was produced by occlusion of bilateral common carotid arteries in rats with following steps: ischemia 20 minutes-reperfusion 10 minutes-ischemia 20(More)
OBJECTIVE To study the volatile regularity of menthol and borneol in granule and lozenge at different temperature. METHOD Kinetic method with GC being detection technique. RESULT The volatility of menthol and borneol acts as a pseudo first-order reaction in open system. Under the same condition, the volatile rate of menthol and borneol in granule is(More)
