Quercus acuta Thunb. (Fagaceae) (QA) is cultivated as a dietary and ornamental plant in China, Japan, South Korea, and Taiwan. It has been widely used as the main ingredient of acorn tofu, a traditional food in China and South Korea. The aim of this study was to determine in vitro and in vivo xanthine oxidase (XO) inhibitory and antihyperuricemic activities of an ethyl acetate extract of QA leaf (QALE) and identify its active phytochemicals using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography (LC) systems...

To evaluate the antibacterial activity of 12 ethanol extracts of Thai traditional herb against oral pathogens. The antibacterial activities were assessed by agar well diffusion, broth microdilution, and time-kill methods. Antibiofilm activity was investigated using a 3-[4,5-dimethyl-2-thiazolyl]-2,5-diphenyl-2H-tetrazolium-bromide (MTT) assay. High performance liquid chromatography (HPLC), thin layer chromatography (TLC) fingerprinting, and TLC-bioautography were used to determine the active antibacterial compounds...

Fufang Xueshuantong (FXT) is a well-known Chinese herbal formula which has been used to treat cardiovascular and ophthalmic diseases, especially diabetic retinopathy. Panax notoginseng (Burkill) F.H. Chen (PN) is the main herb of FXT, whose major bioactive constituents are ginsenosides. However, the scientific basis of the compatibility of FXT is still ambiguous. The present study investigated the scientific basis of the compatibility of FXT by comparing the pharmacokinetics of marker compounds after oral administrations of PN and FXT...

Table olives are especially rich in pentacyclic triterpenic compounds, which exert several biological activities. A crucial step in order to know if these compounds could contribute to the beneficial and healthy properties of this food is their measurement in blood. Therefore, the present study describes a simple and accurate liquid-liquid extraction followed by LC-QqQ-MS analysis for the simultaneous determination of the main pentacyclic triterpenes from Olea europaea L. in rat plasma. The method was validated by the analysis of blank plasma samples spiked with pure compounds, obtaining a linear correlation, adequate sensitivity with a limit of quantification ranging from 1nM for maslinic acid to 10nM for uvaol...

A compound, which is a selective peroxisome proliferator activated receptor (PPAR) agonist, was investigated. The aim of the presented studies was to evaluate the potential of the further development of the compound. Fundamental physicochemical properties and stability of the compound were characterized in solution by liquid chromatography and NMR and in solid-state by various techniques. The drug itself is a poorly soluble lipophilic acid with tendency to form aggregates in solution. The neutral form was only obtained in amorphous form with a glass-transition temperature of approximately 0°C...

Almost no pharmacokinetic compounds to date have been precisely linked with the activity of their herbal or Traditional Chinese Medicine (TCM) formula. This creates challenges for pharmacokinetic significance and application of the TCM. In our study, a sensitive and selective liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed to quantitatively or qualitatively determine multiple-components (tanshinol, ferulic acid, protocatechuic acid, rosmarinic acid, salvianolic acid B, baicalin and 9'-methyl lithospermate B) in rat plasma following the oral administration of Denshen-Chuanxiong-Honghua (DCH) extract (20g/kg)...

The objective of this study was to determine the variation in content of 74 different active pharmaceutical ingredients (APIs) and compare it with what is known in the literature for the content uniformity of extemporaneous prepared capsules. Active pharmaceutical ingredients quantification was performed by high-performance liquid chromatography, via a stability-indicating method. Samples for all active pharmaceutical ingredients were taken throughout a 90-day period and the content was determined. In total, 5,190 different samples were analyzed for 74 different active pharmaceutical ingredients at room (15°C to 25°C) or controlled refrigerated temperature (2°C to 8°C)...

Hydroxycarbamide, available as tablets, is a pharmacological agent for fetal hemoglobin induction such as sickle cell anemia. The need for alternative dosage form options for patients unable to take tablets led hospital pharmacies to prepare solutions and suspensions. The objective of this study was to determine the stability of hydroxycarbamide in Ora-Plus in combination with either Ora-Sweet or Ora-Sweet SF, Ora-Blend, or Ora-Blend SF suspending agents. The studied samples were compounded into 100-mg/mL suspensions and stored in 60-mL amber glass bottles at room (22°C to 25°C) or refrigerated (4°C to 8°C) temperature...

Oral liquids are safe alternatives to solid dosage forms, notably for elderly and pediatric patients that present dysphagia. The use of ready-to-use suspending vehicles such as SyrSpend SF PH4 is a suitable resource for pharmacists as they constitute a safe and timesaving option that has been studied often. The objective of this study was to evaluate the stability of 10 commonly used active pharmaceutical ingredients (allopurinol 20 mg/mL; amitriptyline hydrochloride 10 mg/mL; carbamazepine 25 mg/mL; domperidone 5 mg/mL; isoniazid 10 mg/mL; ketoconazole 20 mg/mL; lisinopril 1 mg/mL; naproxen 25 mg/mL; paracetamol [acetaminophen] 50 mg/mL; and sertraline hydrochloride 10 mg/mL) compounded in oral suspensions using SyrSpend SF PH4 as the vehicle throughout the study period and stored both at controlled refrigerated (2°C to 8°C) and room temperature (20°C to 25°C)...

Scutellariabaicalensis (SB) is a traditional Chinese medicine for treating infectious and inflammatory diseases. Our recent study shows potent antibacterial effects of nanoparticle-encapsulated chlorhexidine (Nano-CHX). Herein, we explored the synergistic effects of the nanoparticle-encapsulated SB (Nano-SB) and Nano-CHX on oral bacterial biofilms. Loading efficiency of Nano-SB was determined by thermogravimetric analysis, and its releasing profile was assessed by high-performance liquid chromatographyusing baicalin (a flavonoid compound of SB) as the marker...

The purpose of this study was to develop extemporaneously compounded oral liquid formulations of aripiprazole for use in pediatric patients and those patients unable to swallow the solid oral dosage forms. Aripiprazole tablets(30 mg) were ground to a fine powder and suspended at a concentration of 1.0 mg/mL in either a 1:1 blend of Ora-Plus and Ora-Sweet, or 1% methylcellulose and Simple Syrup NF. Five amber, plastic liquid prescription bottles of each formulation were stored at 4°C, and aripiprazole content was measured by ultra-performance liquid chromatography time-of-flight mass spectrometry at 0, 14, 32, 67, and 91 days...

Marine invertebrates have been attracting the attention of researchers for their application in nutrition, agriculture, and the pharmaceutical industry, among others. Concerning sea anemones (Cnidaria), little is known regarding their metabolic profiles and potential value as a source of pharmacologically-active agents. In this work, the chemical profiles of two species of sea anemones Actinia equina and Anemonia sulcata, were studied by high-performance liquid chromatography with diode-array detection (HPLC-DAD) and its impact upon immune and gastric cells was evaluated...

Currently the pharmacokinetic (PK) research of herbal medicines is still limited and facing critical technical challenges on quantitative analysis of multi-components from biological matrices which often accompanied by lacking of authentic standards and low concentration. This present work contributes to the development of an integrated strategy for extensive pharmacokinetics assessments, and a selective and sensitive method independent of authentic standards for multi-components analysis based on the use of ultra-performance liquid chromatography/quadrupole-time-of-flight/MS(E) (UPLC-TOF-MS(E)) and UPLC-TOF-MRM (rnhanced target)...

A rapid and sensitive liquid chromatography with tandem mass spectrometry (LC-MS/MS) method was developed and validated for the simultaneous determination of luteolin, luteolin-7-O-glucopyranoside, physalin A, physalin D and physalin L in rat plasma. Scutellarein and dexamethasone were used as the internal standards (IS). Plasma samples were prepared by liquid-liquid extraction with ethyl acetate. The five constituents were separated on an Acquity UPLC BEH C18 column (100 mm × 2.1 mm, 1.7 µm). A gradient elution procedure was used with acetonitrile(A) - 0...
