Mineral oil residues in soil and apple under temperate conditions of Kashmir, India.

The study was undertaken to ascertain the persistence of Orchol-13, a mineral oil used against insect pests of horticultural fruit crops in soil and apple following the dormant and summer applications of 2 and 0.75% respectively. Soil samples were collected during dormant, while as both soil and apple samples were collected during summer season.

Risk assessment, dissipation behavior and persistence of quinalphos in/on green pea by gas chromatography with electron capture detector.

Chemical investigation was carried out to examine the risk assessment, dissipation behavior, persistence, and half-life period of quinalphos in/on green pea fruit by spraying quinalphos at fruiting stage followed by another application after 10-day interval. The samples were extracted by using the quick, easy, cheap, effective, rugged, and safe method, and the residues of quinalphos were analyzed by gas chromatography with electron capture detector. Herein, we report a novel, accurate, and cost-effective gas chromatography method for the determination of average deposits of quinalphos in/on green pea.

Quantification, dissipation behavior and risk assessment of ethion in green pea by gas chromatography-electron capture detector.

Residue investigation was carried out to scrutinize the persistence, dissipation behavior, half-life, and risk assessment of ethion on green pea fruit by spraying ethion at the fruiting stage followed by another application at 10 day intervals. The samples were extracted by using a quick, easy, low-cost, effective, rugged, and safe method, and the residues of ethion were analyzed by gas chromatography with electron capture detection. Here we report a novel, accurate, and cost-effective gas chromatography method for the determination of average deposits of ethion on green pea.

Anthelmintic, antimicrobial, antioxidant and cytotoxic activity of Caltha palustris var. alba Kashmir, India.

The methanolic extract obtained from the root portion of Caltha palustris var. alba was evaluated for its anthelmintic efficacy against gastrointestinal nematodes of sheep under both in vitro and in vivo conditions using worm motility inhibition (WMI) assay and fecal egg count reduction (FECR) assay, respectively. The extract was subjected to antimicrobial activity using agar-well diffusion method against different bacterial strains.

Chromatographic analysis, anti-proliferative and radical scavenging activity of Pinus wallichina essential oil growing in high altitude areas of Kashmir, India.

Purpose: To evaluate the in vitro anti-proliferative and radical scavenging properties of the essential oil and its fractions and to determine the chemo-type of P. wallichiana essential oil.

Method: Pinus wallichiana oil was extracted by hydro-distillation and fractionated by silica gel column chromatography method.
