Medical Role

Because andrographis has a long history of folk medicine in Southeast Asian countries with antibacterial, antipyretic, antineoplastic, anti-inflammatory, cardioprotective effect and so on, the areas where andrographolia is introduced and cultivated are mainly concentrated. Espically andrographolide, neoandrographolide, andrographiside, homoandrographolide, andrographane, andrographanin, andrographone and andrographosterol that is concentrated in the leaves of the plant play the main medical role of andrographis. Of the above chemicals, andrographolide is the major bioactive constituent responsible for variety of activities. Leaves and stems of plant are used for extracting active phytochemicals; roots are used rarely. In this study, improved the extractability of andrographolide from the A. paniculata by ultrasonic assisted extraction, the optimum condition for extracted the andrographolide is determined by response surface experiment and detected the extractability of andrographolide under the optimum condition. By single factor analysis and response surface experiments, the optimum conditions for extracted the andrographolide were the extraction solution concentration 62.8%, the ultrasonic extraction time 59min, the ratio of solid to liquid 1:10.5 and the extraction temperature 62?. Investigate the andrographolide extractability in the optimun extraction condition by HPLC were increased from 2.27% to 3.28%.

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. Surface response methodology digunakan untuk optimasi kondisi ekstraksi. Biji melinjo kerikil diekstrak menggunakan ultrasonic bath pada frekuensi 40 kHz dengan berbagai suhu (25, 30, 35, 40, 45oC), waktu ekstraksi (10, 20, 30, 40, 50 menit) dan konsentrasi pelarut etanol (40, 50, 60, 70 80%). Hasil penelitian menunjukkan bahwa kondisi optimum ekstraksi biji melinjo kerikil berbantu gelombang ultrasonik adalah pada suhu 30,18oC, waktu 33,01 menit dan konsentrasi pelarut etanol 71,04%. Pada kondisi ini, diperoleh yield ekstrak 18,41 ± 0,01%, total fenolik 11,26 ± 0,06 mg GAE/g, total flavonoid 533,70 ± 0,18 mg CE/100g, resveratrol 7,64 ± 0, 03%, IC50 sebesar 59,52 ± 0,04 ppm dan reducing power 76,31 ± 0,08%. Sebagai kesimpulan, optimasi ekstraksi biji melinjo kerikil berbantu gelombang ultrasonik menggunakan response surface methodology ini cukup baik karena nilai respon yang sebenarnya sesuai dengan nilai respon yang diprediksi.Melinjo kerikil seeds contain phenolic and resveratrol compounds so that it has the potential as an antioxidant, therefore extraction needs to be done. Conventional extraction methods (maceration, boiling, refluxing) have the disadvantage of devasting phenolic compounds due to oxidation, hydrolysis and ionization reactions during the extraction process. Therefore, in this study the extraction of melinjo kerikil seeds done by using the ultrasonic-assisted extraction method. The study aims to optimize ultrasonic-assisted extraction of melinjo kerikil seeds that be done at various extraction times, extraction temperatures and ethanol solvents concentrations. Response surface methodology was used to optimize experimental condition for extraction. Melinjo kerikil seeds were extracted by using ultrasonic bath at a frequency of 40 kHz with various temperatures (25, 30, 35, 40, 45oC), extraction time (10, 20, 30, 40, 50 minutes) and ethanol solvents concentrations (40, 50, 60, 70 80 %). The results showed that the optimum conditions for ultrasonic-assisted extraction of melinjo kerikil seeds were at a temperature of 30.18oC, a time of 33.01 minutes and an ethanol solvent concentration of 71.04%. In this condition, obtained the extract yield 18.41 ± 0.01%, total phenolic 11.26 ± 0.06 mg GAE/g, total flavonoids 533.70 ± 0.18 mg CE/100g, resveratrol 7.64 ± 0,03%, IC50 in the amount of 59.52 ± 0.04 ppm and reducing power 76.31 ± 0.08%.

Aurantii fructus (zhiqiao, ZQ) is a traditional Chinese medicine (TCM) and raw material of TCM healthcare food (TCM-HF), mainly focused on the regulation of gastrointestinal disorders and the abundant application of antioxidants. Pharmacological investigations of ZQ flavonoids have identified them as the main bioactive components in recent years, but little has been reported on the extraction processes of antioxidant flavonoids (AFs). The aim of this study was to establish an efficient ultrasonic-assisted extraction (UAE) method for the extraction of AFs from ZQ using a response surface methodology (RSM), analyze the composition of AFs, and develop a qualitative evaluation method for ZQ. Flavonoid yield and antioxidant ability were selected as the responses to optimize the extraction of AFs, and the multiple effects of independent variables were investigated. The optimized conditions for the extraction of AFs based on the Box-Behnken design (BBD) were as follows: ethanol concentration, 58%; extraction temperature, 70 °C; and extraction time, 17 min. The flavonoid yield and antioxidant activity reached 241.70 mg/g and 59.42%, respectively, which matched the predicted values. Furthermore, optimized UAE processes were first established for the efficient and fast extraction of AFs. Flavanones and polymethoxyflavonoids (PMFs) were identified as potential AFs using time-of-flight mass spectrometry. Meanwhile, the quality of ZQ was evaluated using the criteria importance through intercriteria correlation (CRITIC) method for the first time, and Yuanjiang ZQ was considered as an excellent raw material of TCM-HF.

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.
