Efficacy and tolerability of artichoke dry extract (drug/extract ratio 25-35:1, aquous extract, CY450) as coated tablets containing 450 mg extract (tradename: Valverde Artischocke bei Verdauungsbeschwerden) was investigated in the treatment of hyperlipoproteinemia and compared with placebo. 143 adult patients with initial total cholesterol of > 7.3 mmol/l (> 280 mg/dl) were included in a double blind, randomized, placebo controlled, multi-center clinical trial. Patients received 1,800 mg artichoke dry extract per day or placebo over 6 weeks. Changes of total cholesterol and LDL-cholesterol from baseline to the end of treatment showed a statistically significant superiority (p = 0.0001) of artichoke dry extract over placebo. The decrease of total cholesterol in the CY450 group was 18.5% compared to 8.6% in the placebo group. LDL-cholesterol decrease in the CY450 group was 22.9% and 6.3% for placebo. LDL/HDL ratio showed a decrease of 20.2% in the CY450 group and 7.2% in the placebo group. There were no drug related adverse events during this study indicating an excellent tolerability of artichoke dry extract. This prospective study could contribute clear evidence to recommend artichoke dry extract CY450 for treating hyperlipoproteinemia and, thus, prevention of atherosclerosis and coronary heart disease.

This study aimed to determine the effectiveness of different green extraction techniques (GETs) on targeted bioactive compounds from artichoke leaf by-products using deep eutectic solvent extraction (DESE), supercritical CO extraction (SCOE), subcritical water extraction (SWE), and ultrasound-assisted extraction (UAE). Moreover, (HR) LC-ESI-QTOF MS/MS and HPLC-PDA analyses were used to perform qualitative-quantitative analysis on the extracts, enabling the detection of several bioactive compounds, including luteolin, luteolin 7--glucoside, luteolin 7--rutinoside, apigenin rutinoside, chlorogenic acid, and cynaropicrin as the most representative ones. SWE showed better results than the other GETs (TPC: 23.

Caffeoylquinic acids (CQAs) are nutraceutical polyphenols highly represented in natural sources, including artichoke waste (AW). In this study a colorimetric method for rapid and sustainable detection of a 5-CQA isomer (Chlorogenic acid) in AW extract was developed by using alkaline Tris buffer (10 mmol L, pH 9) to generate a yellow color associated with 5- to 3-CQA isomerization reaction, as suggested by NMR and MS analyses. The strong absorbance at 360 nm was followed by standard UV-Vis methodology.

Dithiocarbamates are a class of fungicides widely used in many countries. In this study, methods for determining the ethylene-bis-dithiocarbamate (EBDC) subclass, and their degradation product ethylenethiourea (ETU) were validated by UHPLC-MS/MS in different types of dry herbs, which can be used as food and/or medicinal purposes. Mancozeb was used in the validation of the EBDC method, where it was initially complexed with EDTA, derivatized, extracted with dimethyl sulfate in acetonitrile, magnesium sulfate (MgSO), and sodium chloride (NaCl), and then purified using primary secondary amine (PSA).

The aim of this study was to assess whether dietary supplementation with a nutraceutical blend comprising extracts of bergamot and artichoke-both standardized in their characteristic polyphenolic fractions-could positively affect serum lipid concentration and insulin sensitivity, high-sensitivity C-reactive protein (hs-CRP), and indexes of non-alcoholic fatty liver disease (NAFLD) in 90 healthy individuals with suboptimal cholesterol levels. Participants were randomly allocated to treatment with a pill of either active treatment or placebo. After 6 weeks, the active-treated group experienced significant improvements in levels of triglycerides (TG), apolipoprotein B-100 (Apo B-100), and apolipoprotein AI (Apo AI) versus baseline.
