Abstract:
PicrosideⅡ, one of the most effective components extracted from picrorhiza, has been reported with neuronal protective activity. To isolate the picroside Ⅱ and similar structure moleculars from picrorhiza effectively, molecularly imprinted polymer (MIP) was prepared by precipitation polymerization with Picroside Ⅱ as template molecule and TRIM as cross-linkers. The MIP was with high affinity and excellent stereo-selectivity toward Picroside Ⅱ and similar structure molecular. The purity of picroside is 70% of target sample. This research might offer a novel method for the enrichment and determi

Abstract:
Picrorhiza kurroagrown in the Northwestern Himalayan region is used in various herbal formulations but extensive harvesting of this plant has led it to near extinction. The active constituents responsible for the medicinal properties ofP. kurroahave been identified as picroside-I and picroside-II which are present in a particular ratio (1 : 1.5) in herbal formulations like Picroliv. The biosynthetic pathway of picrosides has been partially deciphered till date and needs to be elucidated completely. Review of literature revealed that no information is available as of today on the proteome analy

Abstract:
The aim of the present study is to determine the physicochemical properties of Picroside-II, a phytochemical obtained from the herb of Picrorhiza kurroa. The solubility study of picroside-II shows that it has better solubility in water up to 2.46 mg/mL than organic solvents. The solubility of picroside-II in linseed oil was found to be 71.46 mg/mL. The solubility of Picroside-II in surfactant like Transcutol P and labrasol was found to be 907.80 and 535.90 mg/mL, respectively. Picroside-II had a melting point in the range of 130 to 135°C. The log P value of picroside-II was estimated using sha

Objective: To optimize the therapeutic dose and time window of picrosede II in cerebral ischemic injury in rats by orthogonal test. Methods The forebrain ischemia model was established by a bilateral common carotid artery occlusion (BCCAO) Method: Rats were randomly grouped according to orthogonal experimental design and treated by injecting picroside II intraperitonenally at different ischemic times with different doses. The concentration of lipid perioxide malondialdehyde (MDA) in serum and brain was determined by thiobarbituric acid assay. The activity of superoxide dismutase (SOD

Abstract:
Background Picroside II (P-II) is the main bioactive constituent of Picrorhiza Kurroa, a traditional Chinese herb of interest for its proven anti-inflammatory properties. Its beneficial effects have been noted across several physiological systems, including the nervous, circulatory, and digestive, capable of treating a wide range of diseases. Nevertheless, the potential of Picroside II to treat osteoarthritis (OA) and the mechanisms behind its efficacy remain largely unexplored.

Abstract:
Picroside I and picroside II are two compounds found in the Picrorhiza Kurroa plant, which have anti-cirrhosis, antioxidant, anti-inflammatory, fever, and asthma effects, etc. They are included in the ingredients of many dietary supplement products that help protect the liver and bile, prevent oxidation, etc. Therefore, determining the content of these two active ingredients in dietary supplements is necessary to evaluate product quality. In this study, highperformance liquid chromatography (HPLC-PDA) was used to simultaneously determine picroside I and picroside II in dietary supplements. The

Abstract:
Chronic obstructive pulmonary disease (COPD) is a major inflammatory lung disease characterized by irreversible and progressive airflow obstruction. Although corticosteroids are often used to reduce inflammation, steroid therapies are insufficient in patients with refractory COPD. Both serum amyloid A (SAA) and IL-33 have been implicated in the pathology of steroid-resistant lung inflammation. Picroside II isolated from Pseudolysimachion rotundum var. subintegrum (Plantaginaceae) is a major bioactive component of YPL-001, which has completed phase-2a clinical trials in chronic obstructive pulm

Abstract:
Picroside II is an active constituent extracted from the traditional Chinese medicine (TCM) Hu-Huang-Lian. To evaluate the neuroprotective effect of picroside II, PC12 cells were treated with glutamate in vitro and male ICR mice were treated with AlCl 3in vivo. Pre-treatment of PC12 cells with picroside II could enhance the cell viability and decrease the level of intracellular reactive oxygen species (ROS) induced by glutamate. By DNA fragmentation and flow cytometry assay, picroside II (1.2 mg/ml) significantly prevented glutamate-induced cell apoptosis. In the animal study, amnesia was indu
