Creep has been known and studied for textile materials for decades. In comparison, a newly observed phenomenon of inverse creep seems not to have received much attention. A new instrument has been fabricated to measure creep and inverse creep in textile materials particularly yarns. Creep and Inverse creep measurements on a few Cotton Yarns at different levels of stress have been studied, using the new instrument and results are reported in the present paper.

Leucas aspera linn. is commonly called as 'Pandharpheda' and is widely distributed throughout south India, having many medicinal properties. A sensitive, simple and accurate HPTLC method has been established for identification and quantification of beta-sitosterol from leucas aspera linn. whole plant powder. Quantification was carried out on pre-coated plate of HPTLC silica gel 60 F254 using mobile phase (toluene: ethyl acetate: formic acid, 12:7:1,v/v/v). CAMAG scanner IV set at visible light (520nm) for detection and quantification. The percentage concentrations of the beta-sitosterol were found to be 0.0672.Response was linear over the range of 0.1μg to 0.5μg with 0.66 and 0.314 of %CV respectively.CAMAG TLC-MS interface was used for the confirmation of m/z values of beta-sitosterol in standard as well as sample. The m/z value was found to be 397(M+H+-H2O). The method i.e. HPTLC and TLC-MS together provides a rapid and secure method for detection, identification and quantification of biomarker betasitosterol.
