The morphological characteristics and chemical composition of plants are shaped by a combination of genetic factors and environmental influences. In particular, plants are continual pressure for variation due to environmental stresses and hybridization. The study aims to assess the chemodiversity among cultivars and clones of Mentha species cultivated under same climatic and soil conditions. The essential oil compositions of 83 samples, representing 11 different Mentha species, were analyzed with Gas Chromatography-Mass Spectrometry (GC-MS). Chemical profiles were classified using multivariate analysis techniques, including Principal Component Analysis (PCA), Hierarchical Cluster Analysis (HCA), and Mean Absolute Deviation (MAD). The results reveal that, despite inter-and intraspecific hybridization in Mentha species, similar chemotypes were observed across different species. Conversely, within the same species, chemotype diversity was present. Centroid clustering also demonstrated that closely related mint species tended to cluster together locally. The analysis identified 16 different chemical groups (chemotypes) among the 83 mint samples studied. Of these 83 samples, 31 were found to be rich in carvone, ranging from 36.4% to 77.7%. In addition to commercial chemotypes such as menthol and menthol/menthone, rare chemotypes were identified, suggesting their potential significance for taxonomic classification. Additionally, the identification of chemotypes containing compounds with newly recognized physiological significance highlights the need to cultivate chemotypes rich in these compounds to meet the growing demands of the industry. Overall, this study sheds light on the chemodiversity within Mentha species and underscores the importance of understanding and harnessing this diversity for various applications.

Sweet pitayas are fruits produced by Stenocereus thurberi. The pulp's fruit is strikingly colored due to the presence of pigments known as betalains. Some chemical and proximal attributes of sweet pitayas vary according to fruit's pulp color suggesting that each variant has a specific nutritional value and genetic information. DNA barcoding is a potential tool to identify the genetic variability of individuals producing different colored pitayas, which can discriminate among variants. In this study, a chemical and a proximal analysis using the pulp of orange, red, and pink sweet pitayas from Sonora (Mexico) were performed. A cluster analysis using pulp color data was carried out to identify clusters of individuals producing the same color. In addition, single and multi-locus barcodes using rbcL, matK and trnH-psbA loci were used to identify possible genetic differences among individuals that produce orange, red, pink, and white sweet pitayas from Sonora. Phylogenetic trees using UPGMA and Kimura-2-Parameter were performed to evaluate the differences among color groups with single and multi-locus barcodes. Some chemical components of pitaya's pulp (i.e., betalains, protein, and titratable acidity), vary according to fruit pigmentation, suggesting that each variant has a specific composition of metabolites. The multi-locus DNA barcode rbcL + matK + trnH-psbA was the best alternative for identifying the genetic diversity of individuals producing sweet pitaya variants of different colors. This approach demonstrates a strong potential for rapid and efficient identification of the biological diversity of pitaya variants, offering an alternative to traditional taxonomic methods.

Rose-scented geranium is an important aromatic crop producing essential oils in India. The study was undertaken during the 2022–23 to 2023–24 cropping seasons at the CSIR-CIMAP, Lucknow, India (80°28′ E 26⁰18 N, 49 m above sea level). The present investigation tried to analyze the GEI in geranium genotypes using the graphical approach of the GGE biplot and to identify lines with good reliability and performance. Geranium cultivars Bourbon, Algerian, CIM-Pawan, Kelkar, CIM-Bharat, and CIM-BIO 171 were examined in multi-year experiments on the Institute's farm using normal production procedures. Six geranium genotypes were grown and analyzed for two years using the GEI-based GGE Graphical biplot technique. There was significant variation among the geraniums in terms of mean yield, performance, and stability, indicating that the bi-plot approach helped with genotype discrimination under varied conditions. In the present investigation, the trait X1 (leaf length) is highly significant and positively correlated with traits such as X2 (leaf width), X3 (leaf area), X4 (leaf node length), X5 (petiole length), X6 (leaf weight), and X7 (leaf yield per plant), but negatively correlated with X8 (essential oil recovery) and X9. The feature X2 is vital and correlates positively with qualities X3, X4, X6, and X7. The two qualities, X8 and X9, were negatively correlated with X2. PC1 and 2 accounted for more than 77.9% of the yield performance variation. GGE biplot analysis revealed that CIM Bio 171 and CIM Bharat outperformed other genotypes regarding stability and mean essential oil yield. In contrast, the Bourbon genotype showed the least amount of yield stability. Thus, genotypes CIM Bio 171 and CIM Bharat will be confirmed and released for large-scale geranium production in India.

Phytochemical investigation of the roots of Lindera glauca led to the isolation of 14 compounds, including four lignanamides (1–4), six hydroxycinnamic acid amides (HCCAs) (5–10), three isoquinoline alkaloids (11–13), and one purine (14). These structures were elucidated on the basis of 1D and 2D NMR spectra (COSY, HSQC, HMBC, and ROESY) and HRESIMS data. Importantly, compound 1 was identified as a new lignanamide derivative, and compounds 2–4 are reported from the Lindera genus for the first time. Meanwhile, compounds 11–14 were reported from the Lauraceae family for the first time. Furthermore, chemophenetics significance of these isolates was also discussed.

The chemical investigation of the Potentilla kleiniana led to the isolation of a new seco-nortriterpene, kleinianene (1), and eight known compounds including one phenylpropanoid glycoside (2), one lignan glycoside (3), one ellagic acid derivative (4), one phenylacetic acid derivative (5), one C₂₁-steroid (6), one polyhydroxyalkylpyrazine derivative (7), one quinoline derivative (8), and one phenolic acid (9). Their structures were elucidated by extensive spectroscopic methods and comparison with literature data. Moreover, the anti-inflammatory activity of 1 was evaluated by measuring its inhibitory effect on NO production in LPS-stimulated RAW 264.7 macrophages. The obtained result showed a moderate inhibition effect of NO release with IC₅₀ value of 26.88 ± 0.36 μM. All the above compounds were isolated from P. kleiniana for the first time and five compounds (2 and 5–8) were first reported from the family Rosaceae. Furthermore, the chemotaxonomic significance of the isolated compounds was discussed briefly.

In this paper, the volatile phytochemical pattern of the resins of five Commiphora Jacq. species collected in Socotra Island was reported. Different populations were studied, some of which for the first time, by using head space-solid phase microextraction (HS-SPME) sampling technique to collect the volatiles emitted from these species. All the captured volatile compounds in the accessions were identified and quantified by means of Gas-Chromatography/Mass Spectrometry (GC/MS). The obtained results highlighted the presence of terpene compounds, mainly monoterpenes and sesquiterpenes, which followed a different trend among the studied species in accordance with the ecology of the collection areas of the species. Sesquiterpenes were predominant in C. kua and, in part, in C. ornifolia; monoterpenes were predominant in C. planifrons and C. parvifolia, whereas oxygenated monoterpenes were predominant in C. socotrana. A high number of the so-called other volatile components were found in C. planifrons. The dominant compounds were γ-cadinene in both accessions of C. kua, β-eudesmol in the first accession of C. ornifolia and δ-cadinene in its second accession, limonene in both accessions of both C. planifrons and C. parvifolia, terpinen-4-ol in both accessions of C. socotrana. The meaning of the data was considered under the chemophenetic, ecological and ethnobotanical aspects.

Chemical analyses of flowering tops of eleven wild populations of Hypericum aviculariifolium subsp. depilatum var. depilatum (Hypericaceae), an endemic species of Turkish flora, identified 25 to 36 volatile secondary metabolites (VSM). Oxygenated monoterpenes such as linalool, camphor and verbenol and sesquiterpenic hydrocarbons such as β-selinene, γ-cadinene and β-caryophyllene were recognized as the main ingredients across populations. This is the first report documenting the variability of volatile secondary metabolites among wild populations of this endemic species. Data acquired were also discussed in terms of their possible chemotaxonomic significance.

This study provides a comprehensive analysis of the flavonoid and volatile compound profiles of leaves, bark, and flowers of Cercis siliquastrum L. Flavonoids were separated via chromatographic techniques and identified using NMR spectrometry and MS, while volatile compounds were analyzed by headspace GC-MS. A total of eight flavonoids (catechin, epicatechin 3-O-gallate, epigallocatechin 3-O-gallate, dihydromyricetin 3-O-rhamnoside, kaempferol 3-O-rhamnoside, quercetin 3-O-rhamnoside, myricetin 3-O-rhamnoside, and myricetin 3-O-glucoside), and 27 volatile compounds were identified. Myricetin 3-O-rhamnoside was detected in a high concentration in C. siliquastrum leaves and flowers, while catechin was predominantly found in the bark. Considering the GC-MS results, aldehydes dominated in C. siliquastrum leaves and flowers, and monoterpenes were the most abundant volatile compounds in the bark. Additionally, an analytical system for flavonoid analysis in C. siliquastrum was established, and the chemophenetic significance of flavonoids in the genus Cercis was discussed.
