Urinary calculi are stones (urolithiasis) that can form anywhere in urinary tract outside of the kidneys and mostly composed of calcium oxalate and phosphate, additionally with elevated throughout the last two decades in the world. Chemical composition plays a major part in nephrolithiasis. Therefore, the high concentrations of lithogenic substances in urine enhance the crystallization method in urine tract system. The most kidney stones form from calcium oxalate, the present study was inspected the effect of the crude aqueous extract as well as the fractionated methanol extract (ethyl acetate, isopropanol, acetone and methanol residue) of paronychia argentea on the crystallization of calcium oxalate salts. The effect of aqueous extract and fractionated methanol extract on the size, number, type of calcium oxalate crystals. Paronychia argentea both the crude aqueous and the fractionated extract, especially ethyl acetate fraction have antiurolithic activity via reducing crystal size as well as activate the formation of calcium oxalate dihydrate (COD) crystals out from calcium oxalate monohydrate (COM) with increasing concentration of extract. The shifting of crystallization process to producing calcium oxalate dihydrate (COD) rather than oxalate monohydrate (COM) and the reducing the crystal size and calcium ion concentration, in addition to the diuretic action of extract plays an important role in controlling urolithiasis.

Abstract The isolation of well formed crystals of the biomineral weddellite (calcium oxalate dihydrate) from Chamaecereus silvestrii, a Cactaceae species found in the northern part of Argentina, is described. Infrared spectroscopic measurements allow an unambiguous characterization of the nature of the crystals. This is the first report of the presence of a biomineral in this plant species.

AbstractPeople of north-eastern states of India consume raw areca-nut (RAN) and lime which could lead to oral, esophageal and gastric cancers. However, the incidence of these cancers are significantly lesser in those who consume pieces of Potentilla fulgens root along with RAN. Since evaluation of anticancer role, if any, of P. fulgens on RAN-mediated genetic alterations in human is difficult because of other compounding factors, this study was undertaken in mice to focus on gastric carcinogenesis since ad libitum administration of RAN extract with lime in drinking water induced stomach cancer due to greater exposure of its lining. A total of 160 mice were used at different time points and either methanol extract of P. fulgens roots (PRE) or mixture of four compounds of ethyl-acetate fraction (EA-mixture) was mixed with mice feed. Histological studies revealed that RAN + lime induced cancer in all the mice and interestingly only 20% developed cancer when PRE/EA-mixture was provided along with RAN + lime. Higher frequency of precocious anaphase and over expression of p53 and Securin genes were significantly reduced by PRE/EA-mixture. Thus PRE/EA-mixture mitigates the RAN-induced tumor-initiating process in stomach by maintaining expression of tumor suppressor and check-point genes under control.

Bioassay Guided Fractionation

Bioassay-guided fractionation of the cytotoxic ethyl acetate fraction of the sequential methanol extract from the leaves and twigs of Dasymaschalon sootepense led to the isolation of a new 7-hydroxy aporphine alkaloid, 6a,7-dehydrodasymachaline (1) along with the five known compounds (-)-nordicentrine (2), dicentrinone (3), (-)-sinactine (4), aristolactam AII (5) and epiberberine (6). Their structures were elucidated by spectroscopic methods. This is the first report of alkaloids 1–2 and 5–6 from the genus Dasymaschalon. Compounds 1 and 5 showed cytotoxicity against a panel of cancer cell lines.

AbstractThe phytochemical and antimicrobial activity of the petroleum ether and crude methanol extracts, chloroform and ethyl acetate fractions of the leaves of Lannea kerstingii were investigated. Phytochemical screening revealed the presence of steroids and triterpenes in the petroleum ether extract, steroid, triterpene, flavonoids and tannins in both crude methanol extract and chloroform fraction while the ethyl acetate fraction contained only flavonoids and tannins. The extracts exhibited antimicrobial activities with zones of inhibition ranging from 17.00 to 21.03, 20.10 to 25.24, 25.32 to 34.02 and 22.28 to 27.20 mm for petroleum ether extract, methanol extract, chloroform and ethyl acetate fractions respectively. The minimum inhibitory concentration was between 5 and 10mg/ml, 5mg/ml for the petroleum ether and methanol extract respectively, and between 2.5 and 5 mg/ml, 5mg/ml for the acetate fractions. The minimum bactericidal concentration for all the extracts was 40mg/ml respectively except for chloroform fraction which ranged from 20 to 40mg/ml. The minimum fungicidal concentration for all the extracts was found to be 40mg/ml respectively. This result indicates the broad spectrum antimicrobial potential of L. Kerstingii and justifies the use of this plant in traditional medicine.
