“…Palmitic acid is an important source of energy for bees. 58 Robustelli della Cuna et al determined that the palmitic acid ratio in S. vomeracea was 0.77%. S. vomeracea and S. orientalis are plant species within the same genus.…”

Conservation biology aims to prevent the decline in biodiversity by reducing the factors that cause it. One way to achieve this is by producing economically valuable orchids in high quantities, allowing humans to rely less on natural populations. In the study, Serapias orientalis seeds were successfully germinated using symbiotic methods and transplanted into a natural field. After 18 months, the plants began to flower, marking the first successful production of S. orientalis in a natural environment. The researchers then analyzed the fatty acid and chemical contents of the leaves and flowers using gas chromatography−mass spectrometry, identifying 28 fatty acids and 19 other substances. The most abundant fatty acids were linoleic acid (21.72%), palmitic acid (20.22%), allylinolenic acid (16.87%), oleic acid (8.67%), and stearic acid (6.13%). Major compounds identified in the methanol extract included hydroxyacetic acid hydrazide (7.38%), semicarbazide hydrochloride (5.06%), DL-glyceraldehyde (5.42%), pentacosane (39.85%), and cholesterol (13.05%). These findings offer a new method for conserving S. orientalis and highlight the potential use of these plants in food, medical, and industrial applications due to their high concentration of bioactive compounds.

“…Some studies of orchids pollinated by oil collecting bees have also used traditional natural product isolation procedures with column chromatography and NMR spectroscopy to identify less volatile compounds such as triterpenes and glycosides, although whether these compounds are involved in pollination remains to be conrmed. 174 For sexually deceptive orchids in particular, there are excellent examples of detailed chemical studies involving preparative chromatography methods. 175 One example is the study by Cuervo et al 63 that fractionated extracts of the European Ophrys leochroma, pollinated by Eucera bees.…”

“…Although Oncidium hybrids are the second most popular varieties of orchids [ 29 ], the secondary metabolome of these plants is still poor elucidated, especially for O. sotoanum . In O. baueri , two recent studies showed that flowers, leaves, pseudobulbs, roots and rhizomes accumulated flavonoid derivatives that belong to the classes of flavanones, such as oncibauerin A and B, and flavones, such as acacetin 7-O-rutinoside and pectolinarigenin-7-O-rutinoside [ 30 , 31 ]. In O.…”

Plants are valuable sources of secondary metabolites with pharmaceutical properties, but only a small proportion of plant life has been actively exploited for medicinal purposes to date. Underexplored plant species are therefore likely to contain novel bioactive compounds. In this study, we investigated the content of secondary metabolites in the flowers, leaves and pseudobulbs of the orchid Oncidium sotoanum using an untargeted metabolomics approach. We observed the strong accumulation of C-diglycosylated chrysin derivatives, which are rarely found in nature. Further characterization revealed evidence of antioxidant activity (FRAP and DPPH assays) and potential activity against neurodegenerative disorders (MAO-B inhibition assay) depending on the specific molecular structure of the metabolites. Natural product bioprospecting in underexplored plant species based on untargeted metabolomics can therefore help to identify novel chemical structures with diverse pharmaceutical properties.
