Introduction: Emblica officinalis is one of the common plants being used traditionally in different ways to search for cures and relief from various diseases. Among these diseases, Emblica officinalis had many of medicinal uses in treating a wide variety of bacterial and fungal infections. In this study, Ultrasonic assisted extraction (UAE) was efficiently used for the preparation of aqueous and methanolic extracts of Embelica officinalis fruits (EOFE). The phytoconstituents was detected through GC-MS/MS analysis to confirm antimicrobial effect of EOFE. Materials and methods: The extraction was carried out at 20{\textordmasculine}C, for 20 min using a solid-to-solvent ratio of 1: 60 w/v. The extracts were subjected to GC-MS/MS analysis. The in-vitro effect of extracts against twenty one microbial strains was investigated by an agar well diffusion method in different concentrations (25 μg/mL-1000 μg/mL). Results: The percentage yield was found to be 41.33\% w/v and 23.0 \% w/v with water and methanol, respectively. Phenol,3,5-bis1,1 dimethylethyl, 2,4-di-tert-butylphenol and heptasiloxa ne1,1,3,3,5,5,7,7,9,9,11,11,13,13-tetradecamethyl were confirmed by GC-MS/MS analysis. Effectiveness of extracts against Gram negative bacteria; Providencia alcalifaciens and Gram positive bacteria; Bacillus pumilis, Bacillus polymyxa and fungal strains; Neurospora crassa, Aspergillus brasileinsis and Cladosporium oxysporum are reported for the first time. Aqueous extract revealed excellent antibacterial activity at 50 μg/mL and antifungal activity at 100 μg/mL whereas methanolic extract showed antifungal activity at 250 μg/mL. Conclusion: Results highlight the considerable inhibitory effect of EOFE against various microbial species was mainly due to the presence of phenolic compounds and other phytocompounds.

Background: NADES is an alternative solvent in the extraction of metabolites from plants which has many environmental benefits, such as low toxicity, biodegradability, can dissolve polar and non-polar compounds, low costs and simple preparation. Objective: This study aims to determine the effect of natural deep eutectic solvent-based ultrasonic-assisted extraction (NADES-UAE) on enrichment of caffeine and chlorogenic acid in extract from green coffee beans (Coffea canephora). Methods: The powders were extracted using NADES-UAE method in several types of extraction condition, including the composition of NADES, water addition in NADES and extraction time. Caffeine and chlorogenic acid content were analyzed using HPLC, reverse phase system and C18 ODS-3 column. Results: The highest of caffeine and chlorogenic acid content was respectively, 7.89 mg/g and 28.62 mg/g (composition of NADES betaine: sorbitol [1:1.2] ratio and NADES-water addition [1:2] ratio for 30 min). Conclusion: This research showed that the composition of NADES, extraction time and water addition are important parameter in extracting caffeine and chlorogenic acid content in green coffee beans.
