Monosodium urate deposits almost exclusively in the connective tissues of patients with gout. Acetone dried homogenates of bovine nasal cartilage, but not of other tissues, markedly enhances the solubility of urate in buffers having molarities and hydrogen ion concentrations similar to that of most body fluids. The components of cartilage responsible for this effect are the proteinpolysaccharides, compounds of protein and chondroitin sulfate, called PPL. A progressive increase in PPL concentration results in a corresponding increase in urate solubility. If, on the other hand, unbound chondroitin sulfate or PPL digested by trypsin is used, then no significant augmentation of urate solubility occurs indicating that the integrity of the molecule is essential. One subfraction of PPL, PPL(5), causes an even more exaggerated response while another, PPL(3), causes a lesser one. These proteinpolysaccharide macro-molecules also inhibit the crystallization of urate from a supersaturated medium. The mechanism of the solubilizing phenomenon is not known. It is suggested that some type of physical or chemical binding is responsible. When, as a result of normal or accelerated connective tissue turnover, PPL is enzymatically destroyed, urate crystals then precipitate from the saturated tissue fluids.

Ranunculus muricatus is commonly known as spiny fruit buttercup and is used in the treatment of intermittent fevers, gout and asthma. Qualitative analysis of phytochemicals of Ranunculus muricatus indicated the presence of saponins, tannins, phenols, flavonoids and alkaloids. Saponins were present in high amount as compared with other chemicals. Inorganic and heavy metals constituents were determined. Heavy metals estimation in the sample showed that iron was present in high amount followed by zinc even then the concentration of these metals is below acceptable limit. The physical parameters, antioxidant and antimicrobial activities of the extracts were determined. Acetone extract fraction showed optimal antioxidant activity as compared to ethanol and chloroform fractions of the candidate plant. The antimicrobial and antifungal activities of the crude extract and extract fractions were determined by well agar diffusion method. Highest zone of inhibitions were observed for crude extract followed by acetone extract fraction against Micrococcus luteus. Antifungal activities were high for crude extracts against Candida Albican. Findings of this study show that Ranunculus muricatus has a good medicinal impact.
