The essential oils were obtained through hydro-distillation using a modified Clevenger-type apparatus. The chromatography-mass spectrometry (GC-MS) was used to assess the chemical composition. Behavioral assays in mice were used to evaluate the antidepressant and anxiolytic effects. In addition, the antioxidant capacity was performed through DPPH, ABTS, and FRAP assays. The GC-MS analysis revealed that linalool (29.16%), bicyclogermacrene (13.32%), nerolidol (12.38%), and β-caryophyllene (10.76%) were the principal components. The results demonstrated significant antidepressant and anxiolytic effects comparable to fluoxetine and diazepam, with statistical differences between all groups (p&amp;lt;0.005). The IC50 values for the DPPH, ABTS, and FRAP assays were 5.9±0.08, 0.20±0.06, and 109.5±1.3, respectively. Consequently, &lt;em&gt;Piper aduncum&lt;/em&gt; essential oil exhibits antidepressant and anxiolytic-like effects and modest antioxidant properties compared to the controls.&lt;/p&gt;

Furthermore, a study was conducted where 128 participants were divided into two groups: a control group and an experimental group treated with essential oils. Stress, anxiety, and sleep quality were evaluated using the Perceived Stress Scale (PSS–10), the Zung Self-Rating Anxiety Scale (SAS), and the Pittsburgh Sleep Quality Inventory (PSQI). In addition, cortisol was measured.&lt;strong&gt; Results:&lt;/strong&gt; Chemical analysis showed thatα-Bisabolol oxide A exhibited the highest concentration at 30.42%, followed by α -Bisabolol (10.94%), α-Bisabolone oxide A (9.82%), and spathulenol (8.83%). Stress, anxiety, sleep quality, and cortisol scores decreased in the post-test study phase compared to the pre-test in the experimental group (p&amp;lt;0.05). Important effect size was found in the case of anxiety (d = 1.203; Δ = 1.246), while medium effects were observed for stress (d = 0.701; Δ = 0.633) and sleep quality (d = 0.888; Δ = 0.732), while cortisol showed small changes (d=0.374; Δ=0.357). &lt;strong&gt;Conclusion:&lt;/strong&gt; The study showed the potential of Chamomile essential oils to reduce stress and anxiety levels and improve sleep quality.&lt;/p&gt;

In this sense, the aim of this work was to evaluate the anticancer and neuroprotective effects of the triterpene glycosides from sea cucumber &lt;em&gt;Holothuria imitans&lt;/em&gt;. &lt;strong&gt;Methods: &lt;/strong&gt;Triterpene glycosides were separated and purified by Reversed-phase high-performance liquid chromatography (RP-HPLC). Their structures were deduced by spectral analysis and chemical evidence. Cytotoxic activity was evaluated using normal African green monkey kidney epithelial cell line (VERO) and three cancer cell lines: cancer gastric (MKN-28), breast adenocarcinoma (MCF-7) and lung carcinoma (A-549). Besides, the neuroprotective effect was studied using the Cath.a-differentiated (CAD) cell line and human glial (Oligodendrocytic) hybrid cell line (MO3.13). &lt;strong&gt;Results: &lt;/strong&gt;Two triterpene glycosides (Fuscocineroside C and Scabraside D) were isolated, which showed low cytotoxic activity against VERO cell line, and high cytotoxic activity against lines MKN-28, MCF-7 and A-549 cells, with IC&lt;sub&gt;50 &lt;/sub&gt;between the ranges of 0.92 μmol/L to 2.61 μmol/L. The isolated triterpene glycosides showed the ability to regain mitochondrial viability in CAD and MO3.13 cells treated with neurotoxin (C2-ceramide) with statistically significant results (p&amp;lt;0.05).&lt;strong&gt; Conclusion: &lt;/strong&gt;The triterpene glycosides Fuscocineroside C and Scabraside D isolated from sea cucumber Holothuria imitans show anticancer and neuroprotective potential and may be considered promising active principles for anticancer and neuroprotective drugs.&lt;/p&gt;

Furthermore, an experimental trial was conducted, where 117 participants were divided into three groups, comprising a waiting list control group and two experimental groups treated with essential oils. The anxiety and depression indexes were evaluated by Zung Self-Rating Anxiety Scale (SAS) and Zung Self-Rating Depression Scale (SDS). &lt;strong&gt;Results: &lt;/strong&gt;chemical analysis showed that trans- Anethole was the main component, both in the essential oil from aerial parts (35.5%) and seeds (79.2%). Anxiety and depression scores showed a decrease in posttest study phase in comparison with pretest in all experimental groups (p&amp;lt;0.05), except for depression scores in the group treated with essential oil from aerial parts (p&amp;gt;0.05). Small changes were found in the case of anxiety for group treated with essential oils from aerial parts (d = 0.41; Δ= 0.40) while moderate (d = 0.86; Δ = 0.85) and small (d = 0.38; Δ = 0.39) changes were found for anxiety and depression respectively, in the group treated with essential oil from seeds. &lt;strong&gt;Conclusion:&lt;/strong&gt; The essential oil from &lt;em&gt;Foeniculum vulgare&lt;/em&gt; seeds is more effective to relief anxiety than depression while the essential oil from&lt;em&gt; Foeniculum vulgare&lt;/em&gt; aerial parts only exhibit small changes for anxiety.&lt;/p&gt;

The aim of this investigation was to determine the anxiolytic-like effect of essential oils extracted from &lt;em&gt;Lippia alba &lt;/em&gt;and &lt;em&gt;Lippia&lt;/em&gt; citriodora. &lt;strong&gt;Methods&lt;/strong&gt;: The oil was extracted by hydro-distillation for 3 hours using a modified Clevenger-type apparatus and then chemical composition was investigated by gas chromatography analysis (GC) and gas chromatography-mass spectrometry (GC-MS). Moreover, a randomized experimental trial was conducted, where 95 participants were divided into 3 groups, comprising a waiting list control group and two experimental groups treated with essential oils by inhalation. The anxiety index was evaluated by State-Trait Anxiety Inventory (STAI). Measures were taken two times: pretest and posttest. &lt;strong&gt;Results&lt;/strong&gt;: chemical analysis showed that carvone was the main component (64.5%) for Lippia alba essential oil and geranial (39.8%) for&lt;em&gt; Lippia citriodora&lt;/em&gt;. State and Trait anxiety scores showed a decrease in posttest study phase in comparison with pretest in all experimental groups (p&amp;lt;0.05). Cohen's D and Hedges’ G scores show a large size effect in state anxiety for experimental group treated with Lippia alba while moderate changes were found for the rest of variables in all experimental groups.&lt;strong&gt; Conclusion&lt;/strong&gt;: the essential oils extracted from &lt;em&gt;Lippia alba &lt;/em&gt;and&lt;em&gt; Lippia &lt;/em&gt;citriodora may be useful as a mean to counteract anxiety, specifically state anxiety showing short-terms benefits.&lt;/p&gt;
