The objective of this study is to focus on boric acid extraction from the mineral tincal, in order to determine the optimum conditions thanks to the ultrasonic-assisted extraction (UAE) technique (with the response surface methodology (RSM) for the first time), and artificial intelligence based swarm intelligence. Characterization of the tincal were done by using thermo-gravimetric assay (TG-DTA), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) analyses. In detail, a central composite design (CCD) was used for determining the effects of different solvent/solid ratios, pH, extraction time, and extraction temperature on the yield, which was determined by the conductometric method. The optimum values regarding the best extraction process was calculated by using five different swarm intelligence techniques: Particle swarm optimization (PSO), cuckoo search (CS), genetic algorithms (GA), Differential evolution (DE), and the vortex optimization algorithm (VOA). In the study content, technical details regarding to background and applied experimental processes are given and the findings pointing an approximate 85–92% boron extraction from tincal ore are discussed generally.

Ultrasonic technology was applied to polysaccharides extraction from Ottelia acuminata (Gagnep.) Dandy and Response Surface Methodology (RSM) was used to optimize the effects of processing parameters on polysaccharides yields. Three independent variables such as liquid-solid ratio (ml/g, X1), extraction temperature (°C, X2) and extraction time (hour, X3) were investigated respectively. The statistical analysis indicated that the three variables and the quadratic of X1 and X3 had significant effects on the yields and followed by the significant interaction effects between the variables of X1 and X3, X2 and X3 (p<0.05). A mathematical model with high determination coefficient was gained.

Chemical composition of n-hexane extracts obtained from dried over-ground parts of two species of Sideritis, S. scardica Grieseb. and S. raeseri Boiss. & Heldr. (Lamiaceae) was analyzed using GC/FID/MS. The collection of plants was made on different locations in the western part of Macedonia and the southern part of Albania, comprising twelve different samples of plant material. The ultrasonic-assisted extraction process was used for preparation of the n-hexane extracts yielded 0.73-3.33 % and 9.11-10.44 % of extracts for S. scardica and S. raeseri, respectively. Over one hundred constituents of the extracts were identified, belonging to several classes of components: diterpenes, hydrocarbons, dominantly present in each of the extracts, followed by fatty acids, aliphatic and aromatic alcohols, sterols, triterpene alcohols, and monoterpenes and sesquiterpenes, which were found in much smaller amounts or only in traces. The most abundant constituents of the extracts of both species of Sideritis were two diterpene components, both with M=286, which were not fully identified. Large percentages of nonacosane (1.71-12.22% and 7.46-19.68% for S. scardica and S. raeseri, respectively) and hentriacontane (4.48-20.79% and 8.09-30.31 % for S. scardica and S. raeseri, respectively) were also found in the extracts of both species.

The increase in durian production results in the accumulation of durian peel waste. The bioactive component of durian peel has the potential to be used as an antioxidant. Thus, there is a need to carry out an extraction process to obtain  bioactive compounds from durian peel. However, conventional extraction methods cause damage to phenolic compounds due to oxidation, hydrolysis and ionization reactions during the extraction process. Therefore, durian peel extraction was carried out using ultrasonic assisted extraction method (UAE) in this study. The purpose of this study was to investigate the effect of varying ratios of durian peel to ethanol solvents and extraction time on the yield, total phenolics content, total flavonoids content and antioxidant activity. The results of the research data were analyzed using a two-factor completely randomized design, which included variations of the ratio of durian peel to ethanol solvents and extraction time The Duncan’s New Multiple Range Test (DNMRT) was carried out as a follow up test to determine the differences in each treatment at a significance level of 0.05. The results showed that the best treatment for peel extraction using ultrasonic assisted extraction was a 1: 9 ratio of durian peel to ethanol at an extraction time of 20 minutes. The extraction of durian peel under this condition gave the highest yield of 12.77 ± 0.16%, antioxidant activity (IC50) of 38.33 ± 0.12 ppm, total phenolic content of 63.30 ± 0.08 mgGAE / g and total flavonoids content of 47.53 ± 0.48 mgQE / g. In addition, total phenolics content and total flavonoid content showed a strong correlation to the antioxidant activity of durian peel extract.

In this study, bioactive compounds were extracted by ultrasonic-assisted extraction and classical extraction processes using distilled water as solvent from artichoke leaves which are considered as agricultural wastes. Antioxidant capacity, total phenolic and total flavonoid content values of the obtained bioactive extracts were determined, and extraction yields and times were evaluated to compare the extraction processes. Also, the optimum extraction conditions of ultrasonic-assisted extraction (extraction time and ultrasonic power) which provide the highest extraction yield were determined using D-optimal design by ‘desirability’ function approach. According to the results, bioactive extracts having high antioxidant capacity were obtained at shorter times and higher extraction yields were achieved by ultrasonic-assisted extraction process than classical extraction. The highest extraction yield was estimated as 98.46% with an application of 20.05 minutes of extraction time and 65.02% of ultrasonic amplitude for the ultrasonic-assisted extraction process.

Biji melinjo kerikil mengandung senyawa fenolik dan resveratrol sehingga berpotensi sebagai antioksidan, oleh karena itu perlu dilakukan ekstraksi. Metoda ekstraksi konvensional (maserasi, perebusan, refluxing) mempunyai kelemahan yaitu terjadinya kerusakan senyawa fenolik akibat reaksi oksidasi, hidrolisis dan ionisasi selama proses ekstraksi. Oleh karena itu, pada penelitian ini ekstraksi biji melinjo kerikil dilakukan menggunakan metode ekstraksi berbantu gelombang ultrasonik. Penelitian ini bertujuan untuk optimasi ekstraksi biji melinjo kerikil berbantu gelombang ultrasonik yang dilakukan pada berbagai waktu ekstraksi, suhu ekstraksi dan konsentrasi pelarut etanol.
