Objective: To study the chemical constituents of Suregada glomeruldata.
Method: Isolation and purification were carried out on silica gel, sephardex LH -20, ODS column chromatography etc. Constituents were identified by physicochemical properties and spectral analysis.
Result: Nine compounds, Jolkinolide B (1), 8alpha, 14-dihydro-7-oxo-jolkinolide E (2), helioscopinolide B (3), ent-kauran-16beta, 17-diol (4), 7-oxo-beta-sitosterol (5), scopoletin (6), adenosine (7), 1'-sinapoylglucose (8), sucrose (9), were obtained and identified.
Conclusion: Compounds 2-9 were isolated from S. glomerulata for the first time.

Improper management of wood impregnation chemicals and treated wood has led to soil contamination at many wood treatment sites, particularly with toxic substances like creosote oil and chromated copper arsenate (CCA). The simultaneous presence of these pollutants complicates the choice of soil remediation technologies, especially if they are to be applied in situ. In this laboratory study, we attempted to immobilise arsenic (As) and simultaneously degrade polycyclic aromatic hydrocarbons (PAHs) (constituents of creosote oil) by applying a modified electrochemical oxidation method.

Background & Aim: Hemolytic anemia is a blood disorder whose incidence is increasing in the world in recent years especially after the pandemic. Conventional treatments include use of steroids and immunosuppresants that are accompanied by numerous adverse effects. With growing interest in using complex multi-component formulations for multi-targeted therapy, the present study aims to investigate the therapeutic efficacy of a traditional herbomineral preparation, , which has been traditionally used as a supplement in iron-deficiency anemia, against phenylhydrazine-induced hemolytic anemia in rodent models.
