Background: Plukenetia volubilis L., Inca peanut is an oleaginous plant, widely cultivated as commercially in South East Asia, especially in Thailand. The oil from the seed plant is a greatest interesting a natural source. Objectives: The aims of this study were investigated phytochemical screening, to evaluated the total flavonoids and phenolic compound contents as well as antioxidant activities of seedling extract from P. volubilis. Methods: The dried P. volubilis seedlings of 21 days growing period were extracted by using different solvent including aqueous (ASS), 50\% ethanolic (HESS), and 95\% ethanolic (ESS) extracts. The phytochemical screenings were determined on total phenolic compound (TPC) and flavonoid (TFC) contents. The antioxidation were tested by using 2,2-diphenyl-1-picrylhydrazy radical scavenging (DPPH), 2,2 -azinobis-(3-ethylbenzothiazoline-6-sulphonate) (ABTS+) assay, and ferric reducing antioxidant power (FRAP). Results: The results found that the ESS were significantly highest amount on total phenolic compound (23.0809{\textpm}0.8632 mgGE/gExt ) and flavonoid (466.3839{\textpm}1.5580 mgQE/gExt) contents. In this study, ascorbic acid (IC50 =0.016{\textpm}0.0003 mg/mL) and Trolox (IC50 =0.044{\textpm}0.0008 mg/mL) as standard substances were showed more potent than all of the extracts from P. volubilis seedlings. Surprisingly, the ESS has more potent on free radical scavenging higher than different solvents; DPPH=0.007{\textpm} 0.001 (IC50=mg/mL), ABTS= 1.4065{\textpm} 0.0505 (IC50=mg/mL),and FRAP= 74.4960{\textpm} 2.6067 (mg=TE/gExt). Conclusion: the plant seedling extracts composed with high amount of flavonoids and phenolic compound contents possess valuable to antioxidant activities. The seedling extracts from the plant could apply to supplementary food, cosmetic, pharmaceutical, and horticultural industries. Next study, chemical compositions, the major active compound(s), and biological activities will be clarified.

Context: Plant from the Lamiaceae family are considered as dietary spices and medicinal herbs traditionally used in medicine for the treatment of several pathologies. Objective: Evaluation of the in vitro antibacterial activity of ethanol and aqueous extracts of nine Moroccan plants from the Lamiaceae family against six bacterial strains regularly implicated in toxiinfection. Method: The antibacterial activities of hot (HAE), cold (CAE) aqueous extracts and ethanolic extracts (EE) were evaluated using agar-well diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and IC50 against six foodborne bacteria (Bacillus cereus, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella enterica). Total phenolic and flavonoid contents were assessed as well. Results: In the present study, the ethanol extracts were rich in polyphenols, with middling values of flavonoids, and relatively poor in condensed tannins. The presence of saponins, essential oils, irroides, alkaloids, anthocyanins, and aldehydes was recorded. The effect of the extracts was directly bactericidal for B. cereus and L. monocytogenes; for the other strains, the MBC value was twice higher than that of MIC. However, the ethanol extract (EE) of O. majorana and T. satureioides showed the highest antibacterial activity. With the principal component analysis, it was demonstrated that the nine Lamiaceae family plants possess a powerful antibacterial effect, correlated with their phenolic content. Statistical analysis: Analysis of variance was performed by uni-varied ANOVA in the software SPSS 22 Fr. Conclusion: The active compounds were thermostable and soluble in ethanol and water. The antimicrobial activities of the plants extracts investigated may contribute to understand their involvement in traditional medicine against many microbial infections.
