Altered biomass allocation and quality improvement in roots of Indian . through physiological interventions.

Ashwagandha (), known as Indian , contains three major bioactive compounds, withaferin-A (WA), 12-deoxywithastramonolide (WO) and withanoloide A (WD). In a field experiment, the impacts of foliar application of growth retardants/promoters was assessed with respect to biomass allocation pattern and major withanoloide content at different phenological stages in Biomass accumulation pattern showed that foliar application of 500 mg lethrel at 50, 65, 85, 105, and 120 days after sowing (DAS) restricted phenological progression and reduced berry weight by 61% as comparted to the control at 160 DAS. 500 mg l succinic acid foliar application resulted in maximum plant height (56.

Accumulation of three important bioactive compounds in different plant parts of Withania somnifera and its determination by the LC-ESI-MS-MS (MRM) method.

A comprehensive experiment was conducted to study the accumulation pattern and determination of three important bioactive compounds namely withaferin-A (WA), 12-deoxywithastramonolide (WO) and withanolide-A (WD) and its determination by the liquid chromatography/electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS) method in root, stem, fruits and leaves of Withania somnifera. A rapid and sensitive LC-ESI-MS-MS method was developed and validated for the determination of these three important bioactive compounds, having same molecular weight. The multiple reaction monitoring method was established by two transitions for each analyte and intense transition used for quantification.

Next Generation Sequencing and Transcriptome Analysis Predicts Biosynthetic Pathway of Sennosides from Senna (Cassia angustifolia Vahl.), a Non-Model Plant with Potent Laxative Properties.

Senna (Cassia angustifolia Vahl.) is a world's natural laxative medicinal plant. Laxative properties are due to sennosides (anthraquinone glycosides) natural products.
