The discovery and identification of novel natural products of medicinal importance in the herbal medicine industry becomes a challenge. The complexity of this process can be reduced by dereplication strategies. The current study includes a method based on high-performance liquid chromatography (HPLC), using the evaporative light scattering detector (ELSD) to identify the 12 most common secondary metabolites in plant extracts. Twelve compounds including rutin, taxifolin, quercetin, apigenin, kaempferol, betulinic acid, oleanolic acid, betulin, lupeol, stigmasterol, and β-sitosterol were analyzed simultaneously. The polarity of the compounds varied greatly from highly polar (flavonoids) to non-polar (triterpenes and sterols). This method was also tested for HPLC-DAD and HPLC-ESI-MS/MS analysis. Oleanolic acid and ursolic acid could not be separated in HPLC-ELSD analysis but were differentiated using LC-ESI-MS/MS analysis due to different fragment ions. The regression values (R2 > 0.996) showed good linearity in the range of 50–1000 µg/mL for all compounds. The range of LOD and LOQ values were 7.76–38.30 µg/mL and 23.52–116.06 µg/mL, respectively. %RSD and % trueness values of inter and intraday studies were mostly <10%. This method was applied on 10 species of medicinal plants. The dereplication strategy has the potential to facilitate and shorten the identification process of common secondary metabolites in complex plant extracts.

"The development of novel routes for the production of functional textiles is an urgent need. Natural dyes are a safe and sustainable choice for the colouration of textiles. To achieve the colouration of textiles with natural dyes, mordanting methods have been highly explored; the present work targets the functional natural dyeing of cotton by the in-situ development of azoic dye. The paper discusses a new application approach of a novel natural dye (derived from conical prickles of Bombax ceiba bark) to cotton using mosquito repellent ethyl anthranilate. The dye obtained from the extract of Bombax ceiba bark conical prickles (CPBCE) was further converted into azoic dye by reacting it with diazotised ethyl anthranilate. The developed coloured cotton fabric was endowed with mosquito repellence, antibacterial action, and UV protection. The colouration properties and fastness of dyed samples were examined using standard methods. Moreover, the dyed samples were also characterised using TGA (thermogravimetric analysis) and XRD (X-ray diffraction) analysis. Thus, 100% mosquito repellent properties, good antibacterial protection, and excellent UV protection were imparted to cotton."
