“…It is not surprising that the identified spectral features play a crucial role in distinguishing almonds cultivated in areas with diverse pedoclimatic conditions. This is because perturbations in precipitation patterns and water availability have a significant impact on the synthesis of secondary metabolites in plants, both in terms of quantity and quality, thereby influencing their flavor, aroma, and medicinal characteristics [35][36][37][38].…”

Almonds are the seeds of the almond (Prunus Amygdalus) tree and are a nut consumed worldwide. The present study utilized the ATR FT-IR technique followed by a chemometric analysis to develop predictive models for determining the geographical origin of almonds from three regions in Southern Italy (Apulia, Calabria, and Sicily). IR spectra were collected on both the almond shell and the edible kernel to accurately characterize the three different geographical origins. The spectroscopic data obtained were processed using Soft Independent Modeling of Class Analogies (SIMCA) and Partial Least Squares Discriminant Analysis (PLS-DA). Both SIMCA and PLS-DA revealed that the shell spectra are more useful for assessing the geographical origin of samples. In particular, the PLS-DA model applied to these data achieved a 100% correct classification rate (on the external test set of individuals) for all the investigated classes.

“…Medicinal plants serve as a universal remedy for several ailments because of the potent secondary metabolites such as alkaloids, polyphenolic compounds, terpenes, carotenoids etc. These metabolites help plants to cope up with the adverse effect of oxidative stress generated through environmental variables (Suyal et al 2019a). Phenolic compounds, tannins, avonols and avonoids of Himalayan medicinal herbs has been identi ed for their antioxidant (Giri et al 2017), anti-in ammatory and anti-cancer activity (Singh and Patra 2018) etc.…”

“…In addition, proteins, amino acids and polyphenols are also recorded from roots and lactones in stems and leaves (Wang et al 2006). P. cirrhifolium is adapted in several ecological habitats having prevalent variations in environmental conditions which ultimately affect the superiority and e cacy of the ultimate produce (Suyal et al 2019a). Thus, evaluation of quality resources of P.cirrhifolium is essentially required.…”

Polygonatum cirrhifolium is an important medicinal herb of family Asparagaceae used to cure several ailments. Its rhizome forms an important ingredient of "Chyavanprash" which is identi ed for its rejuvenating properties. However, P.cirrhifolium is least explored scienti cally and systematically till date. Therefore, in this study genetic diversity and phytochemical variations along with antimutagenic activity of P.cirrhifolium populations was evaluated. Antimutagenic activity varied remarkably (p<0.05) having Gagar population with signi cantly (p<0.05) higher DNA recovery (84.95%) percentage. Higher genetic diversity (He) was recorded among populations using RAPD (He, 0.30-0.36) and ISSR (0.25-0.38) markers. High intra and low inter population variations were recorded in the species using both kinds of markers. Phenolics (p<0.05; r=0.924); tannins (p<0.05; r=0.897) and DNA damage inhibition e ciency displayed a highly positive correlation with genetic diversity (estimated using ISSR markers). The population structure analysis of P. cirrhifolium revealed that the greatest value of the K was 3 for studied populations. Gene ow among studied populations was found su cient to encounter genetic erosion in the species. Therefore, it can be recommended that the populations with higher ingredient and genetic diversity can be utilized for conservation priority and management plan of this species.

“…The value of each parameter, including pseudobulbs weight, pseudobulb growth ratio, polysaccharide content, total phenols content, militerane content and GRA (Tables 2 , 3 , and 4 ), in each population was categorized into five equal classes, and population in class 5 with higher values were considered as a prioritized group of the population [ 34 ]. At the same time, the sum of the one-, two-, three- and four-year-old pseudobulb weight, and the average of polysaccharide, total phenols and militerane content in one-, two-, three- and four-year-old pseudobulb were used for prioritization and elite identification.…”

Background The Bletilla genus of Orchidaceae includes plants with great economic value, among which B. striata is the main traditional medicinal plant, and its pseudobulb, known as BaiJi, was first recorded in Shennong’s Classic of Materia Medica. However, there has been little systemic evaluation of the germplasm quality of Bletilla plants in China. In order to comprehensive evaluate the Bletilla resources in China and screen out the candidate phenotypic traits determining yield and/or quality of Bletilla, the variation of phenotypic indicators (pseudobulb, leaf, stem, inflorescence, flower) and active ingredients contents (polysaccharide, total phenolics and militarine) in different populations of B. striata and B. ochracea were investigated through 4 years’ common-garden experiment. Results There were abundant phenotypic variations and significant differences among different populations in the morphological phenotypes, pseudobulb weight and main active ingredient contents. AHBZ, HBLT and HBSN populations showed good prospects for industrial development, presenting higher quality in terms of yield and main active ingredient content. Pseudobulb yield, polysaccharide and total phenol content are positively correlated with phenotypic traits. Militarine content is negatively correlated with almost all indexes. Plant height, leaf width and stem diameter may be important indicators of potential excellent germplasms. Conclusions Bletilla is not strictly geoauthentic medicinal plants. B. ochracea could be accepted as an alternative resource to B. striata. The best harvest period of Bletilla is the third year after cultivation. Plant height, leaf width and stem diameter may be important indicators of potential excellent germplasms. These results provide important information required for the efficient screening and utilization of Bletilla germplasm resources.
