Multiresidue analysis of 200 pesticides in jasmine (Jasminum sambac (L.) Aiton) flowers

A multiresidue analysis method was established for 200 pesticides in jasmine (Jasminum sambac(L.) Aiton) flowers based on QuEChERS procedure and gas chromatography-tandem mass spectrometry (GC–MS/MS). For better recoveries and purification effects, extraction solvents, extractive salts and purification methods were optimized. The limits of quantification (LOQ) of test pesticides are in the range of 0.01 and 0.1 mg kg−1, most of which were below the maximum residue limits (MRLs) prescribed by EU and China. Recoveries at 0.01, 0.1, 1.0 mg kg−1 were predominantly in the range of 70–120 % (n = 3) with corresponding RSDs lower than 20 %, which suggests satisfactory accuracy. The multiresidue analysis method was applied in monitoring pesticide residues in 8 jasmine flower samples. 50 % of those samples present with 1–2 pesticides residues. This study provides a sensitive and high-throughput method for detection of multi-pesticide residues in jasmine flowers.

The tea cultivar ‘Chungui’ with jasmine-like aroma: From genome and epigenome to quality

‘Chungui’ is a newly promoted tea cultivar in China, renowned for producing oolong tea with a distinctive jasmine-like aroma. However, the genetic basis of this unique aroma remains unclear. In this study, the ‘Chungui’ genome, one of the most complete and well-annotated tea genomes, was assembled using PacBio HiFi reads and Hi-C sequencing. Through comparative analysis with typical jasmine flower volatiles, eight core compounds responsible for this aroma were identified. Further research revealed that the jasmine-like aroma in ‘Chungui’ is regulated by a coordinated mechanism involving a significant increase in chromatin accessibility and the demethylation of CHH and CHG in the promoter regions of key aroma-related genes during oolong tea processing. The study proposes that the formation of this unique aroma is driven by the synergistic effect of enhanced chromatin accessibility and reduced methylation, which together lead to the robust upregulation of genes involved in the biosynthesis of these core aroma components. These results provide a molecular foundation for understanding the unique jasmine-like aroma of ‘Chungui’ tea and sets the stage for future studies to explore the roles of these regulatory mechanisms in aroma formation.

Synthesis and clinical efficacy of novel jasmine titania tooth whitening gel on color, surface roughness and morphology

ObjectiveTo analyze the beneficial role of novel jasmine titania tooth whitening gel on the color, surface roughness and morphology of human tooth enamel, concerning age. MethodsGreen dentistry incorporating Jasmine flower extract was used to fabricate titania (titanium oxide) nanoparticles whose physicochemical characteristics were evaluated through X-ray diffraction spectroscopy, scanning electron microscopy, dynamic light scattering spectroscopy, atomic force microscopy and energy dispersive X-ray spectroscopy in order to produce a novel jasmine tooth whitening gel. This whitening gel was applied on maxillary central incisors ranging between 20 and 50 years, which were investigated for color change, surface roughness and morphology. ResultsThe titania nanoparticles depicted 100 % pure anatase phase, 30.3 nm size and a spherical shape with no impurities. The color change (whitening) was found to be maximum in tooth enamel from the youngest age group (20 years), but minimum for the oldest age group (50 years) (p = 0.001). No significant change in surface roughness or morphology of tooth enamel belonging to the youngest age group (20 years) (p = 0.111) and middle age group (p > 0.05) was observed, but it was statistically significant in the teeth belonging to the ultra-middle age group (40 years) and the oldest age group (50 years) (p = 0.001). ConclusionNovel jasmine titania tooth whitening gel containing titania (titanium oxide) nanoparticles prepared by jasmine flower extract revealed potent whitening effects in all the age groups without affecting their surface roughness or morphology. Clinical significanceThe latest trends emerging in aesthetic dentistry show the demand for cosmetic procedures, especially tooth whitening, is enhanced. This novel jasmine titania tooth whitening gel was potent enough to whiten the enamel belonging to different age groups without enhancing the surface roughness or adversely affecting the surface morphology.

Phytometabolites from coral jasmine flower extracts: Toxic effects on Spodoptera litura and enzyme inhibition in nontarget earthworm Eisenia fetida as an alternative approach

Green pesticides, derived from natural sources, have gained wider attention as an alternative to synthetic pesticides for managing polyphagous pests, such as Spodoptera litura. In this study, the methanolic flower extract of Nyctanthes arbor-tristis (Mx-Na-t) was subjected to chemical screening, and 3-hydroxy-1,2-dimethyl-4(1H)-pyridone (3H-dp) and tyrosol (Ty-ol) were identified as the major derivatives. The toxic effects of Mx-Na-t (500 ppm) were highest in third-instar S. litura larvae (96.4%), while those of 3H-dp and Ty-ol (5 ppm) were highest in second-instar larvae (76.5% and 81.4%, respectively). The growth and development of S. litura larvae and pupae were significantly reduced by all three treatments. Fecundity rates were also reduced by all treatments [from 1020 eggs (control) to 540 eggs by Mx-Na-t treatment, 741 eggs by 3H-dp treatment, and 721 eggs by Ty-ol treatment]. The extract and its active constituents decreased adult emergence and slowed total larval development in a dose-dependent manner. A decrease was noted in the major gut enzymes of young S. litura larvae exposed to Mx-Na-t, 3H-dp, and Ty-ol. Moreover, midgut tissues of fourth-instar larvae were severely damaged by Mx-Na-t (250 ppm), 3H-dp (2.5 ppm), and Ty-ol (2.5 ppm); the treatments induced structural damage to the epithelial cells and gut lumen. The earthworm Eisenia fetida was used to assess nontarget toxicity. Compared with cypermethrin, the phytochemicals exhibited minimal effects on the earthworm's detoxifying enzymes superoxide dismutase and catalase after 14 days of treatment. Moreover, in silico predictions using BeeTox and ProTox-II indicated little or no toxicity of 3H-dp and Ty-ol toward honey bees and other nontarget species.

The neural representations of valence transformation in indole processing.

Indole is often associated with a sweet and floral odor typical of jasmine flowers at low concentrations and an unpleasant, animal-like odor at high concentrations. However, the mechanism whereby the brain processes this opposite valence of indole is not fully understood yet. In this study, we aimed to investigate the neural mechanisms underlying indole valence encoding in conversion and nonconversion groups using the smelling task to arouse pleasantness. For this purpose, 12 conversion individuals and 15 nonconversion individuals participated in an event-related functional magnetic resonance imaging paradigm with low (low-indole) and high (high-indole) indole concentrations in which valence was manipulated independent of intensity. The results of this experiment showed that neural activity in the right amygdala, orbitofrontal cortex and insula was associated with valence independent of intensity. Furthermore, activation in the right orbitofrontal cortex in response to low-indole was positively associated with subjective pleasantness ratings. Conversely, activation in the right insula and amygdala in response to low-indole was positively correlated with anticipatory hedonic traits. Interestingly, while amygdala activation in response to high-indole also showed a positive correlation with these hedonic traits, such correlation was observed solely with right insula activation in response to high-indole. Additionally, activation in the right amygdala in response to low-indole was positively correlated with consummatory pleasure and hedonic traits. Regarding olfactory function, only activation in the right orbitofrontal cortex in response to high-indole was positively correlated with olfactory identification, whereas activation in the insula in response to low-indole was negatively correlated with the level of self-reported olfactory dysfunction. Based on these findings, valence transformation of indole processing in the right orbitofrontal cortex, insula, and amygdala may be associated with individual hedonic traits and perceptual differences.

The Effectiveness of a Combination of Lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and Jasmine Flower (Jasminum nudiflorum) Extracts as and Environmentally Friendly Corrosion Inhibitor

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes

Assessment of Micronutrient Status in Jasmine (Jasminum azoricum L.) Growing Soils of Huvina Hadagali Taluk, Vijayanagara District of Karnataka, India

The present study was conducted during winter (November‑December, 2022) in Jasmine growing area of Huvina Hadagali Taluk, Vijayanagara District to assess the soil micronutrient status in Jasmine growing area and analysed for their fertility parameters. A total of 60 soil samples were collected, of which 30 surface (0‒20 cm) and 30 subsurface (20‒40 cm) soil depths covering six villages namely Huvinahadagali, Hanakanahalli, Vinobhanagara, Meerakornahalli, Devagondana-halli and Thippapura. In surface soil, available micronutrients boron, zinc, iron, copper and manganese ranged from 0.45 to 1.28, 0.24 to 0.98, 1.17 to 7.90, 0.30 to 3.76 and 2.44 to 22.52 mg kg-1, respectively. Mean soil pH was 7.96, mean soluble salt was 0.27 dS m-1 and soil organic carbon ranged from 2.40 to 6.80 g kg-1. In subsurface soil, available micronutrients boron, zinc, iron, copper and manganese ranged from 0.36 to 1.09, 0.16 to 0.80, 0.96 to 6.76, 0.16 to 2.72 and 1.84 to 20.86 mg kg-1, respectively. Mean soil pH was 8.06, mean soluble salt was 0.32 dS m-1 and soil organic carbon ranged from 1.60 to 6.00 g kg-1. The results showed that depending on the nutrient nature, their concentration was either found in the range of deficit, or sufficient or in excess due to poor nutrient management practices like continuous use of chemical fertilizers and less use of organics which results in poor soil fertility leading to low yield and low quality of Jasmine flowers.
