Kaempferia L., a medicinal genus of Zingiberaceae family, is widely distributed from India to Southeast Asia and is rich in terpenoids, flavonoids, phenolics, and volatile oils. Recently, it has gained attention for its diverse biological activities, including antioxidant, anticancer, analgesic, anti-inflammatory, and anti-tuberculosis effects. However, several Kaempferia species complexes exhibit similar morphological characteristics, making identification and classification challenging. This study integrates morphology, molecular phylogeny, and phytochemistry to identify and distinguish Kaempferia species. Phylogenetic relationships were reconstructed using four DNA barcoding markers: one nuclear region (ITS) and three chloroplast markers ( mat K, rbc L, and psb A- trn H). Untargeted metabolomic analysis using SPME-GC-MS, combined with multivariate statistical analyses, was employed to resolve species relationships and display volatile profiles among 15 Kaempferia species from two subgenera. A total of 217 metabolites were identified by the SPME-GC-MS technique. Variable Importance in Projection (VIP ≥ 1.5) analysis indicated 30 key metabolites, primarily sesquiterpenes, as specific chemotaxonomic markers. This study provides a comprehensive chemical profile of Kaempferia species and highlights metabolomic differences among them. Our findings emphasize the importance of integrating morphological, molecular, and phytochemical approaches for precise identification of closely related species, particularly within Kaempferia . This chemotaxonomic research also provides further applications for species authentication in pharmaceuticals and medicine.

is a genus belonging to the ginger family. Currently, this genus is comprised of about 63 species, mainly distributed from India to Southeast Asia. During our fieldwork, a new species of was found in Chon Buri Province, Thailand. The objective of this article was to provide morphological evidence and confirm its relationships in through molecular phylogenetic analysis. Plant samples were collected from field sites and investigated by conventional taxonomy and molecular techniques. The phylogenetic trees were reconstructed using the maximum likelihood criterion and Bayesian inference. The morphological evolution was also examined to elaborate the relationships among representative taxa. from southeastern Thailand is described and illustrated based on morphological features and its taxonomic placement was confirmed by molecular phylogenetic analyses and morphological evolution. An identification key is provided for the new species occurring in Thailand. is a new enumerated species of from Thailand.

Plumbago indica L. has a various pharmacological activity; however, the anticancer activity in cervical cancer has less information. To examine the antiproliferative, apoptotic, and antimigratory activity of Plumbago indica root extract on cervical cancer cells. The extract of P. indica was explored for cell viability, apoptosis, and migration by sulforhodamine B, colony formation, cell cycle distribution, Wound healing, Annexin V-FITC staining apoptotic, mitochondrial function, and reactive oxygen species (ROS) formation. The data indicated that P. indica extract suppressed HeLa cervical cells viability by dose- and time-dependent manner along with the reduction of cancer cell number and colony forming ability. After 48 h of incubation period, the PR extract exhibited a significant reduction of migratory ability by dose-dependent manner. Furthermore, these extracts significantly showed a reduction of cell viability along with induction of late apoptosis. The mechanism of action was shown by detecting mitochondrial dysfunction and activating of ROS formation on HeLa cells-treated with P. indica extract. The extract of P. indica has a growth inhibition, migratory suppression, and apoptotic induction. The extract has an anticancer activity by reducing mitochondrial function and activating ROS formation.
