L-dopa, a dopaminergic agonist, is the gold standard for the treatment of Parkinson's disease. However, due to the long-term toxicity and adverse effects of using L-dopa as the first-line therapy for Parkinson's disease, a search for alternative medications is an important current challenge. Traditional Ayurvedic medicine has suggested the use of Linn.

Introduction: Asparagus racemosus Willd (Asparagaceae family), known as Shatavari, is important in Ayurveda and traditional Thai medicines. The saponin glycosides, shatavarin I and IV are major constituents in its roots and may be responsible for their actions including protection against lipid peroxidation and carcinogenesis.

Objective: To develop an immunoaffinity column for isolating compounds with structures related to shatavarin IV from crude extracts of A.

High performance centrifugal partition chromatography (HPCPC) was applied to the rapid isolation and purification of saponin glycosides in Asparagus racemosus Willd. root. A two-phase solvent system composed of CHC13-MeOH-water (4:4:2, v/v) in descending mode was used for the separation, yielding shatavarin.

The objective of this study was to investigate thermal and mechanical properties as well as in vitro drug release of Eudragit® RL (ERL) film using chlorpheniramine maleate (CPM) as either active pharmaceutical ingredient or non-traditional plasticizer. Differential scanning calorimeter was used to measure the glass transition temperature (Tg) of 0-100% w/w CPM in ERL physical mixture. Instron testing machine was used to investigate Young's modulus, tensile stress and tensile strain (%) of ERL film containing 20-60% w/w CPM.

Introduction: Bacopa monnieri contains pseudojujubogenin glycosides as pharmacologically active compounds. In order to screen large numbers of plant samples for the presence of pseudojujubogenin glycosides, a rapid and simple assay system is required for application to small quantities of test materials. Immunoassays using monoclonal antibodies could be useful for the determination of small quantities of pseudojujubogenin glycosides in plant extracts.

Aim Of The Study: Bacopa monnieri (Brahmi) is extensively used in traditional Indian medicine as a nerve tonic and thought to improve memory. To examine the neuroprotective effects of Brahmi extract, we tested its protection against the beta-amyloid protein (25-35) and glutamate-induced neurotoxicity in primary cortical cultured neurons.

Materials And Methods: Neuroprotective effects were determined by measuring neuronal cell viability following beta-amyloid and glutamate treatment with and without Brahmi extract.
