“…The value of viscosity solution was caused by the elevated of the extraction temperature, which then reduces the mass transfer resistance, so that the solid particle cell network softens and facilitates the transfer of the solute to the solvent [18]. This is to the research of Tambun et al [19] regarding the extraction of galangal which showed that a temperature of 60°C produced the highest total phenol. In addition, the results of Ananta et al [18] stated that the total phenol content will continue to increase for up to 36 hours, and will decrease at 48 hours of maceration The effect of time and temperature of extraction on velvet bean extract's total flavonoid compounds (TFC) can be seen in Figure 3.…”

Mucuna pruriens L. is a type of legume with high total phenolic and flavonoid compounds and may be a source of antioxidants. Bioactive and chemical components contained in velvet beans were obtained through maceration. Temperature and time of extraction were needed to obtain the optimal extract. The present study aims to explore temperature (30-60°C) and time (120-360 minutes) of the extraction effects on total phenol compounds (TPC), total flavonoid compounds (TFC), total tannin compounds (TTC), and the antioxidant capacity: 1, 1-diphenyl-2-picrylhydrazyl radical - scavenging activity (DPPH-RSA), 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid radical - scavenging activity (ABTS+-RSA), and ferric reducing antioxidant power (FRAP) of velvet beans using double factor experiments approach. All of the studies extraction conditions indicated a significant effect (p < 0.05) on yield, TPC, TFC, TTC, DPPH-RSA, ABTS+-RSA, and FRAP. These results pointed that velvet beans extract for 60°C at 360 minutes was the highest content of TPC, TFC, and TTC were obtained with values of 41.78 mg GAE/g, 309,65 mg QE/g, and 237,13 mg TAE/g. The antioxidant capacity was 38.15 mg AAEAC/g on DPPH-RSA, 6.36 mg AAEAC/g on ABTS+-RSA, and 35.06 mM FE2+ /g on FRAP.

“…Ukuran partikel dari kayu gaharu merupakan salah satu faktor yang mempengaruhi proses ekstraksi. Pengecilan ukuran dapat memperluas permukaan bahan sehingga mempermudah pelarut untuk dapat melakukan penetrasi ke dalam kayu gaharu [16]. Jumlah perbandingan pelarut, dan lama waktu ekstraksi akan mempengaruhi jumlah yield.…”

“…Sedangkan ukuran partikel halus > 40 mesh tidak berbeda dengan ukuran 0,1 -0,5 cm. Hasil ini menunjukkan bahwa adanya peningkatan pada yield sebesar 0,18% diakibatkan oleh pengecilan ukuran partikel yang berdampak pada semakin banyaknya poripori yang terbentuk sehingga terjadi peningkatan jumlah minyak atsiri yang mudah diserap [16] dan banyak partikel yang saling berekasi [12]. Akan tetapi pengecilan ukuran hingga >40 mesh tidak berdampak peningkatan yield minyak atsiri gaharu dan dapat menyebabkan penggumpalan sehingga sulit untuk permease pelarut [16].…”

“…Perolehan yield yang meningkat pada rasio dibawah 1:11 (b/v) dikarenakan jumlah volume pelarut yang lebih banyak menyebabkan senyawa aktif yang terdapat pada kayu gaharu terdifusi keluar senada dengan konsep perpindahan massa. Akan tetapi yield minyak atsiri gaharu mulai sedikit konstan dan bahkan terjadi sedikit penurunan pada rasio 1:11 disebabkan oleh fenomena kejenuhan pelarut terhadap konsentrasi senyawa aktif [16]. Pelarut yang jenuh pada zat terlarut menyebabkan proses difusi pada sel kayu gaharu terhenti melalui penurunan laju stabilitas senyawa yang diekstrak [20].…”

Agarwood is one of the forest products that can be utilized and has a high selling value. Agarwood contains essential oils which have many active compounds and contains a specific aromatic resin that is naturally formed as a form of defense against physical damage or microbial infection. Agarwood essential oil with good quality has a high economic value. This study aims to extract agarwood essential oil using ethanol as a solvent. The optimal yield of agarwood essential oil can be obtained by varying the particle size, the ratio of the weight of the agarwood biomass (kg) to the volume of the solvent (L), and the length of maceration (h). The results showed that the particle size of agarwood did notaffect the yield of agarwood essential oil. The results of the comparison of agarwood biomass with the volume of the solvent showed that the ratio of 1:9 (w/v) obtained the highest yield of 4.02% and the longest maceration time with the highest yield of 4.12% for 72 hours. However, 48 hours of maceration had a greater increase in yield compared to 72 hours of maceration. The increase in yield at 48 hours to 72 hours of maceration was only 0.22% when compared to the increase in yield at 24 hours to 48 hours of maceration, which was 0.56%.

“…Ultrasonic can also reduce the extraction temperature and can be used in the extraction of bioactive compounds that are not resistant to high temperatures (Zou et al, 2014). The research of Rondang Tambun et al (2017) stated that the phenol content of red galangal extract using ultrasonic was highest at 9 hours with a temperature of 60°C at 45%. In addition, Handayani, Sriherfyna and Yunianta (2015) research stated that antioxidant extraction in soursop leaves was best treated at 45°C in 20 minutes with a yield of 11.72%, total phenol content of 15,213.33 ppm, 45,843 ppm flavonoid content, and antioxidant activity of 78.14%.…”

Introduction. Black potato (Plectranthus rotundifolius) is one of the tubers in Indonesia and not well known by the public. It causes inadequate use of black potato than any other tubers. The parts that are currently used are the potato flesh. Meanwhile, the black potato peels are not used. Although the black potato peels contain polyphenol saponins, flavonoids, and antioxidant compounds. Method. Phytochemicals can be separated using extraction methods, one of the modern extraction methods used is the ultrasonic bath method. The ultrasonic bath method is a method that uses ultrasonic waves with a frequency greater than 16-20 KHz. The objective of this research is to determine the phytochemical content and antioxidant activity of lowland black potato peels with cow manure using ultrasonic bath extraction method. The research was conducted experimentally using RAL (Completely Randomized Design) with 3 factors and 3 replications, which included the difference in extraction temperature (55°C); extraction time (15 and 20 minutes); and the ratio of materials and solvents (1:5 and 1:10). Results & Analysis.The data obtained were yield, total phenolics, total tannins, flavonoids and antioxidant activity of black potato peels extracted using ultrasonic bath method with different temperature, extraction time and solvent ratio. The data obtained were analyzed using the Anova test with a significance of α = 0.05. Discussion. The analysis indicated that the treatment of 5 kg/plot manure with an extraction time of 20 minutes, at a temperature of 55°C, and a ratio of ingredients and solvents is 1:10 provided the best quality at 4.13% moisture content, 17.90% yield, 0.177 g/g phenols total, 0.063 g/g tannins, 0.096 g/g flavonoids and 45.275 ppm antioxidant activity.
