Worldwide, there are plants known as psychoactive plants that naturally contain psychedelic active components. They have a high concentration of neuroprotective substances that can interact with the nervous system to produce psychedelic effects. Despite these plants' hazardous potential, recreational use of them is on the rise because of their psychoactive properties. Early neuroscience studies relied heavily on psychoactive plants and plant natural products (NPs), and both recreational and hazardous NPs have contributed significantly to the understanding of almost all neurotransmitter systems. Worldwide, there are many plants that contain psychoactive properties, and people have been using them for ages. Psychoactive plant compounds may significantly alter how people perceive the world.

Cotton aphids, Aphis gosspyii and cotton jassids, Amrasca biguttula are destructive piercing sucking pests to many strategic crops, especially cotton, not only in Egypt but also all over the world. Using synthetic pesticides to control these pests led to several deleterious impacts. Natural pesticides can be used as a harmless alternative. Nine compounds were isolated from different fractions of Retama raetam using chromatographic techniques and identified by spectroscopic methods as eugenol (1), alpinumisoflavone (2), licoflavone C (3), ephedroidin (4), anagyrine (5), spartiene (6), genistein-8β-C-glucoside (7), isoprunetin (8) and isoprunetin 7-O-β-D-glucopyranoside (9). The methanol crude extract and its fractions (hexane, chloroform, ethyl acetate and butanol), as well as the isolated compounds were examined against A. gosspyii and A. biguttula as insecticides. The results showed that chloroform fraction was the most potent fraction against A. gosspyii and A. biguttula, with LC50 values of 65.66 and 64.43 ppm, respectively. As well, compounds 1, 5 and 6 were found to be more active, with LC50 values of 69.84, 25.49 and 27.22 ppm for A. gosspyii and 65.17, 24.07 and 24.78 ppm for A. biguttula, respectively. The most potent compounds (1, 5 and 6) exhibited AChE inhibition toward A. gosspyii compared with the control. So, it can be concluded that the isolated compounds eugenol 1, anagyrine 5 and spartiene 6 are the active principles due to their capability to inhibit AchE activity. Copyright © 2023 Elsevier B.V.

A Comparative Study on Improving Streptozotocin-Induced Type 2 Diabetes in Rats by Hydrosol, Extract and Nanoemulsion Prepared from Cinnamon Leaves. Huang YC(1), Chen BH(1)(2).

Cinnamomoum osmophloeum Kanehira (C. osmophloeum) contains various biologically active antioxidant compounds such as flavonoids, phenolic acids and cinnamaldehyde. Type 2 diabetes mellitus is a chronic disease of metabolic abnormality caused by insulin deficiency or resistance. The objectives of this study were to analyze various bioactive compounds in C. osmophloeum leaves by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and compare the effects of hydrosol, extract and nanoemulsion prepared from C. osmophloeum leaves on improving type 2 diabetes in rats. Our results show that a total of 15 bioactive compounds in C. osmophloeum leaves, including quercetin, quercetin-3-O-galactoside, quercetin-3-O-glucoside, rutin, caffeic acid, benzoic acid, 5-O-caffeoylquinic acid, kaempferol 3-β-D-glucopyranoside, trans-cinnamic acid, coumarin, cinnamyl alcohol, p-coumaric acid, eugenol, kaempferol and cinnamaldehyde, were separated within 14 min for subsequent identification and quantitation by UPLC-MS/MS. The nanoemulsion was successfully prepared by mixing C. osmophloeum leaf extract, soybean oil, lecithin, Tween 80 and deionized water in an appropriate proportion with a mean particle size, polydispersity index, zeta potential and encapsulation efficiency of 36.58 nm, 0.222, -42.6 mV and 91.22%, respectively, while a high storage and heating stability was obtained. The animal experiment results reveal that the high-dose nanoemulsion was the most effective in reducing both fasting blood glucose and oral glucose tolerance test value, followed by low-dose nanoemulsion, high-dose extract, low-dose extract and leaf powder in hydrosol. A similar trend was shown in reducing serum insulin and the homeostatic model assessment of insulin resistance index. In addition, the contents of serum biochemical parameters, including total cholesterol, triglyceride, aspartate aminotransferase, alanine aminotransferase, uric acid, urea nitrogen and creatinine, were reduced, with the high-dose nanoemulsion showing the most pronounced effect. Collectively, the high-dose nanoemulsion may possess great potential to be developed into a hypoglycemic health food or botanic drug.

Different plant parts of Ligusticopsis wallichiana (family: Apiaceae) are widely used as traditional medicines. Although many volatile constituents are already identified from the leaves of L. wallichiana, there is no detailed report on the nonvolatile constituents. In the present study, we aimed to isolate and identify the major chemical constituents from the leaves. Bhutkesoside A (1), falcarindiol (2), ferulic acid (3), cnidioside A (4), quercetin 3-O-β-D-glucopyranoside (5), rutin (6), 4'-O-methylquercetin 3-O-β-D-glucopyranoside (7), scopoletin (8), umbelliferone (9), eugenol 4-O-β-D-glucopyranoside (10) and pumilaside A (11) were isolated from the 70% MeOH extract. The structures of isolated compounds were elucidated on the basis of 1H- and 13C-NMR spectroscopic data. Compounds 4-11 are reported for the first time from L. wallichiana. Compounds 5 and 6 showed potent free radical-scavenging activity. DOI: 10.1155/2018/1794650 PMCID: PMC5816836 PMID: 29484213 4. Zhongguo Zhong Yao Za Zhi. 2013 Nov;38(21):3696-701.

Yang L(1), Yan C, Zhu J, Song L, Yu R. Author information: (1)Department of Pharmacy, Fujian Tumor Hospital, 350014, Fuzhou, China, apera@163.com. The biocatalytic ability of transgenic crown galls of Panax quinquefolium was evaluated by using eugenol (1) as a substrate and suspension cultures of Nicotiana tabacum as control system. Three biotransformed products, namely: 2-methoxy-4-(2-propenyl)phenyl-O-β-D-glucopyranoside (2, 67.11%), 2-methoxy-4-(2-propenyl)phenyl-O-β-D-glucopyranosyl (6' → 1″)-β-D-xylopyranoside (3, 2.85%) and methyl eugenol (4, 14.30%) were obtained after 5 days of administration of eugenol to the suspension cultures of transgenic crown galls of P. quinquefolium. In contrast, only one product, compound 2 (15.41%), was obtained in suspension cultures of N. tabacum after 5 days of incubation. The results indicated that the glycosylation ability of transgenic crown galls of P. quinquefolium was much higher than that of the cultured cells of N. tabacum.
