During the present study an analytical method based on reverse-phase high performance liquid chromatography photodiode array detection method was developed for simultaneous determination of withaferin-A and withanolide-A in plant parts of two cytotypes (diploid n=12 & tetraploid n=24) of Physalis angulata. All the plant parts were extracted in different solvent solutions i.e., acidic [HCl] methanol, methanol, n-hexane, chloroform. Both the compounds were comparatively analyzed. The results revealed that tetraploid cytotype (n=24) showed the higher composition of both the reference compounds. The HPLC separation process was performed on Attantis T3 Column (5µm pore size, 4.6mm×250mm) with diode-array detection held at 25°C utilizing, acetonitrile and water as mobile phase at flow rate of 0.8mL/min in isocratic elution. Calibration curves produced satisfactory linear regression (r 2 >0.999) for each examined sample. The method is simple, rapid and provides better resolution can be easily applied to the quantitative analyses of withanolides in plant matrices.

BackgroundThe present work aimed to verify whether intermediate variants were natural crosses between Datura species (D. stramonium forms and D. ferox). Their existence has been long ago insinuated but has not been studied using morphological features and molecular tools. The variants differed in stem coloring, upper bearing forks, and fruit characters.ResultsPrincipal Components Analysis of 11 morphological characteristics showed that D. ferox and D. stramonium (forms stramonium and tatula) were quite different and the putative hybrids were intermittent. The D. ferox × D. stramonium f. tatula was closer to the latter of its parents. Sequencing analysis revealed identical amplified trnL intron in all variants and a 100% homology with D. stramonium accession number EU580984.1 suggested that this plastid cannot discern Datura variants. However, genomic analysis with URP markers indicated that the hybrids had >60% genetic makeup similarity with both parents suggesting that the intermediate variants were putative inter-specific hybrids. Moreover, the dendrogram stemmed from cluster analysis of the fingerprint profile of variants placed D. stramonium and D. ferox in different branches indicating their genetic differentiation from each other as well as from their hybrids.ConclusionsThe findings suggest that the natural hybridization of annual Datura species occurs. Extrapolating, this hybridization could be the first step for speciation. More possibly, it can alter population composition, its weediness and adaptability to local conditions.
