Introduction: Sea cucumbers has gained notoriety because possess a wide range of biological and pharmacological activities. In this sense, the aim of this work was to evaluate the anticancer and neuroprotective effects of the triterpene glycosides from sea cucumber Holothuria imitans. Methods: 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). Results: 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 IC50 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\<0.05). Conclusion: 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.

Introduction: Essential oils from natural plants are widely use around the world to relief mental conditions. The aim of this investigation was to determine the anxiolytic-like effect of essential oils extracted from Lippia alba and Lippia citriodora. Methods: 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. Results: chemical analysis showed that carvone was the main component (64.5\%) for Lippia alba essential oil and geranial (39.8\%) for Lippia citriodora. State and Trait anxiety scores showed a decrease in posttest study phase in comparison with pretest in all experimental groups (p\<0.05). Cohen{\textquoteright}s D and Hedges{\textquoteright} 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. Conclusion: the essential oils extracted from Lippia alba and Lippia citriodora may be useful as a mean to counteract anxiety, specifically state anxiety showing short-terms benefits.
