Industrially used and endangered listed medicinal plantAndrographis paniculatawas cultivated between rows of ten-year-oldMorus alba(mulberry) plantation, spaced at 10′ × 10′ under a Randomized Block Design, already existed for sericulture purposes, and evaluated for its performance in terms of content of its three major bioactive diterpene lactones 14-deoxy-11,12-didehydroandrographolide, andrographolide, and neoandrographolide to examine the effect of intercropping on these constituents. Matured plants were harvested and the aerial parts were shade dried, milled, defatted, and extracted with methanol. The extracts were analyzed using HPLTC method validated for linearity, precision, specificity, and accuracy in accordance with the ICH guidelines. Pure lactones required for quantitative determination were isolated from column chromatography of the ethylacetate fraction of the methanol extract obtained from the aerial parts of the plant. Densitometric quantification was performed on Silica gel 60F254pre-coated glass plates with a mobile phase of chloroform:methanol (7:1,v/v) in a twin trough chamber saturated for 20 min. Statistical analysis revealed significant increase in the contents of these lactones in theA. paniculatawhen intercropped than grown as sole crops. Thus, suitability of intercropping ofA. paniculatain mulberry based cropping system was demonstrated. [ABSTRACT FROM PUBLISHER] |
