This current work describes the preparation of MgO‐SBA‐15 catalysts by ultrasonic method, and it is characterized by the different analysis techniques of XRD, BET, SEM, and IRTF. In order to find out an application for this mesoporous material, MgO/SBA‐15 was used as a heterogeneous catalyst in the one‐pot synthesis of pyrano[3,2‐c]chromenes derivatives isolated at room temperature reaction according to green chemistry criteria. To enhance these derivatives, a spectroscopic study of molecular fluorescence properties was carried out as well as an identification analysis by nuclear magnetic resonance and FTIR was used. Furthermore, biological activity experiment is also carried out, from where the obtained test results were satisfactory for AC09, AC05, and AC10 compounds and they are checked after computation by molecular modeling.

Deverra scoparia Coss. & Dur. (Apiaceae) from Algerian Sahara was dried by two methods, conventional (sun, open air) and microwave at different powers (264, 400, 800 W). The essential oils (EOs) were obtained from the different samples by hydrodistillation and analyzed by gas chromatography coupled with mass spectrometry (GC-MS). 32 constituents were identified and the oils compositions were found to be dominated by Myristicin (43.44–69.73%), D-Limonene (6.61–12.57%), Dillapiole (0.74–10.87%), α-Phellandrene (0.47–8.16%) and α-Pinene (4.36–8.10%) as the main constituents. Then, the EOs were evaluated for their insecticide activity against the white cochineal of the date palm Parlatoria blanchardi Targ (Hemiptera- Diaspididae) by the spraying method, thus the inhibition activity of its acetylcholinesterase (AChE). The obtained results showed an important efficacy of the EOs against this insect with lethal doses (LD50) ranged from 2.32 to 6.12 µL/mL. Moreover, the study of the inhibition of AChE showed a strong inhibitory effect against this enzyme, with an EC50 value of 0.002 µL/mL. These results suggest that this plant might be efficient as potential alternative control agents for Parlatoria blanchardi Targ.
