“…Other works are in accordance with our results as a greater value of trans-3-Gg concentration than trans-4-GG is also registered when stigmas are dried in the shade or freeze-dried [35,36]. However, under these different methods of dehydration, contrary results have also been obtained [36,37]. Therefore, it can be mentioned that these two compounds are the main crocetin esters of saffron.…”

The dehydration process is the basis to obtain high quality saffron and to preserve it for a long time. This process modifies saffron’s main metabolites that define its quality, and are responsible for the characteristic color, taste, and aroma of the spice. In this work, the effect of microwave dehydration on saffron main metabolites (picrocrocin, safranal and crocetin esters) from Crocus sativus L. stigmas at three determinate powers and different time lapses was evaluated. The results showed that this dehydration process obtained similar or lower crocetin esters content, and after three months of storage, higher concentration was shown in treatments at 440 W for 36 s, 55 s, and 73 s; at 616 W for 90 s; and at 800 W for 20 s. Picrocrocin content was lower and safranal content was higher in all treatments compared to the control both before and after storage. Regarding to commercial quality, microwave dehydration obtained Category I of saffron according to International Standard Organization (ISO) 3632. After three months of storage, treatments at 616 W for 83 s and 800 W for 60 s obtained lower categories. The results obtained suggest that microwave dehydration is a suitable process for obtaining high quality saffron, 800 W with 6 lapses of 20 s being the best conditions studied.

“…Unfortunately, these factors could not be ascertained in the current study since the samples were not collected from cultivated plants, but from plants that grew in the wild. A recent study on some plant extracts also demonstrated that geographical location had a significant effect on the composition and content of secondary metabolites [17,27]. This could explain the differences noted on the metabolites detected in pod samples collected from different locations in the current study and their intensities that are shown in the heatmap.…”

“…Previous studies have reported the profiles and compositions of metabolites that are present in the pods [10,15]. It is known that different geographical regions could affect the composition and quality of the plants [17]. Therefore, the aim of this study was to characterize P. speciosa pod profiles, sampled from different regions in Malaysia using a highly sensitive metabolomics-based ultra-high-performance liquid chromatography-quadrupole time of flight/tandem mass spectrometry (UPLC-ESI-QTOF/MS) and α-glucosidase assay.…”

Parkia speciosa is a food plant that grows indigenously in Southeast Asia. A great deal of interest has been paid to this plant due to its traditional uses in the treatment of several diseases. The pods contain many beneficial secondary metabolites with potential applications in medicine and cosmetics. However, studies on their phytochemical properties are still lacking. Therefore, the present study was undertaken to profile the bioactive compounds of P. speciosa pods collected from six different regions of Malaysia through ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-QTOF-MS) and α-glucosidase inhibitory potential. This study applied metabolomics to elucidate the differences between P. speciosa populations found naturally in the different locations and to characterize potential α-glucosidase inhibitors from P. speciosa pods. P. speciosa collected from different regions of Malaysia showed good α-glucosidase inhibitory activity, with a median inhibitory concentration (IC50) of 0.45–0.76 μg/mL. The samples from the northern and northeastern parts of Peninsular Malaysia showed the highest activity. Using UHPLC-QTOF-MS/MS analysis, 25 metabolites were identified in the pods of P. speciosa. The findings unveiled that the pods of P. speciosa collected from different locations exhibit different levels of α-glucosidase inhibitory activity. The pods are a natural source of potent antidiabetic bioactive compounds.

“…Recent studies have shown the effect of viral infection on secondary metabolite accumulation in plants [20]. In saffron which is highly appreciated for its colour and aroma, the presence of viral disease has been shown to modify the important secondary metabolite content responsible for its valuable properties [21,22]. These reports suggest that virus infection not only affect the total yield loss but can also reduce the crop quality at the nutritional level in the surviving plants.…”

Occurrence of Cotton leaf curl Multan virus and associated betasatellites with leaf curl disease of Bhut-Jolokia chillies (Capsicum chinense Jacq.) in India

et al. 2021

Geminiviridae comprises the largest family of plant viruses which causes severe crop losses in India. The highest pungency chilli Bhut-Jolokia or ghost pepper (Capsicum chinense Jaqc.) hails from North-East region of India and is used in many dishes to add flavors and also for its medicinal value. However, this chilli variety is also affected by viruses leading to crop and economic losses. The present study reports the identification of begomoviruses in the infected chilli Bhut-Jolokia leaf samples collected from eight different places of North-East region (Manipur) of India. The infected leaf samples were screened for the presence of viral genome by rolling circle amplification (RCA) followed by PCR using degenerate primer pairs. The subsequent analyses using restriction fragment length polymorphism and sequencing revealed the presence of Cotton leaf curl Multan virus (CLCuMuV), and Tomato leaf curl Patna betasatellite (ToLCPaB). The findings focus on the phylogenetic relatedness, probable recombinational hot-spots and evolutionary divergence of the viral DNA sequences with the current reported begomoviral genome. To the best of our knowledge, this is the first report showing the presence of CLCuMuV, and associated non-cognate ToLCPaB with leaf curl disease of Bhut-Jolokia chillies. The study reveals potential recombination sites on both viral genome and betsatellite which, during the course of evolution, may have aided the virus to progress and successfully establish infection in chilli plants. Taken together, our results suggest a possible spread of CLCuMuV to the hitherto non-host crop in the North-East region of India.
