“…One such minor crop is Jasmine (Jasminum sambac (L.) Aiton), a shrub belonging to the genus Jasminum from the Oleaceae family. It was originally from India but is now widely distributed in southern China and around the world (Ray et al 2014;Lavanya et al 2016). Jasmine ower can not only be used as ingredients to make perfumes and essential oil because of its strong fragrance, but it can also be used to make oral teas for human consumption (Zhou et al 2022; Khammee et al 2021).…”

For minor crops such as jasmine, the lack of pesticide registration and maximum residue limits are important issues that need to be solved in order to facilitate trading and ensure food safety. Meanwhile, reliable and quick analytical methods for multi-pesticide residues in these commodities are few, but required by various stakeholders. In this study, a method for detecting 25 of the most frequently used pesticides in jasmine ower and its scented tea by multi-plug ltration cleanup and ultra-high-performance liquid chromatography-tandem mass spectrometry was developed and validated. The cleanup process was optimized and compared with the dispersive solid phase extraction procedure. Results showed that the relative standard deviations of multi-plug ltration cleanup method in precision tests were smaller. The absence of any solvent evaporation, vortices and additional centrifugation processes made this approach more rapid. The method was validated, showing that except for methomyl, recoveries of 25 pesticides were 64-108%, with relative standard deviations (n = 5) of 0.33-10%. The method was successfully applied to detect pesticide residues in marketed jasmine ower and scented tea samples. The results showed that some samples contained a combination of different residues, with neonicotinoids, organophosphates and pyrethroids being the three main types detected in both ower and tea samples.

“…Its odor has widely used in many ways. In some fashion, people have traditionally used its aroma to relax the body and mind since the ancient time [19]. However, it is still unclear to explain how the jasmine odor affects our body, especially on an electrocardiogram response, in quantitative point of view.…”

“…The participated subjects in our experiment were also from Southeast Asia and Asia countries. Jasmine can be found easily in many places around India, Thailand and Southeast Asia and Asia countries [19]. Jasmine oil is the natural essential oil which was extracted from jasmine flowers and it has a sweet floral aroma.…”

Analysis of physiological and psychological responses to odor stimulation

Heart rate variability (HRV) analyses as well as Stress Response Scale-18 (SRS-18) questionnaire were used to evaluate the effect of Jasmine-odor inhalation in males and females. Healthy 15 males (26.3 ± 3.7 years) and 15 females (30.1 ± 3.4 years) participated in the experiment. Standard Lead-II ECG data were collected for resting, control and odor stimulation conditions. The instantaneous heart rate variability tachogram was interpolated with the use of cubic spline interpolation, and then, FFT was performed to find the HRV power spectrum. HRV frequency domain analysis parameters were low frequency range (LF: 0.04 - 0.15Hz), high frequency range (HF: 0.15 - 0.4 Hz) and the ratio of normalized low frequency to high frequency (nLF/nHF). HRV time domain analysis parameters in this research were heart rate (bpm), the standard deviation of all normal to normal RR intervals (SDNN) and root mean square of successive RR intervals difference (RMSSD). Experimental results suggest that stress of both males and females decreased after exposing to odor (p<0.05). It was also found that heart rate decreasing rate of males was faster than that of females for odor sets. SDNN and RMSSD parameter were slightly increased in both odor and control experiment but not so much difference in both males and females. The nLF/nHF ratio of males are significantly higher than females in all measurement intervals (p<0.05). This might be intrinsic character of males and females. After odor exposure, the nLF/nHF ratio was slightly decreased in male subjects while it was slightly increased for all control intervals. Decreasing the nLF/nHF ratio might link to decreasing the stress. The nLF/nHF ratio in female subjects was not so much changed in both odor and control intervals with slightly increased trend. The results indicate that ECG measurement could be used to evaluate the stress state quantitatively. It will be alternative technique for stress evaluation other than using the qualitative measurement with SRS scale.
