“…In this regard, in Figure 1c, it is observed that within the range of 1 to 6 mL/g of water raw material ratio, the extraction yield increased, and reached the highest value when the ratio was 6 mL/g. Similar results were observed by Yin & Dang (2008) and Yan et al (2014) when extracted polysaccharides from BaChu mushroom and leaves of Gynura bicolor respectively. These authors mentioned that the increase of water raw material ratio may increase diffusivity of the solvent into vegetable cells, so desorption of the polysaccharides from the cells is enhanced.…”

“…In this study, the linear terms X1 (temperature extraction) and X2 (extraction time) affect significantly (p < 0.05) the response FEY. Other studies reporting the significant influence of temperature and time on extraction yield of polysaccharides from vegetable sources are those conducted by XuJie & Wei (2008) and Yan et al (2014). Also, Bouaziz, et al (2014) observed that water temperature had a significant influence on the extraction yield of polysaccharides from Agave americana leaves.…”

Agave tequilana Weber azul variety is a valuable source of fructans. In this study, a response surface methodology was employed to optimize the extraction yield of fructans from agave pines. A Box Behnken factorial design was applied to evaluate the effects of several conditions such as extraction temperature, water raw material ratio and extraction time on extraction yield. Under the optimum extraction conditions (extraction temperature of 79.1 °C, water raw material ratio of 5.13 mL/g, and extraction time of 1.48 h) fructans extraction yield was 83.12%. The chromatographic profile of the agave crude extract presented four peaks, out of which fructans were the most preponderant (~87%). The obtained results suggest that the response surface methodology is adequate to optimize fructans extraction from Agave tequilana Weber azul variety.Keywords: fructans; agave; extraction yield; optimization; response surface methodology.Practical Application: Response surface methodology allows the optimization of fructans extraction from Agave azul.

“…Extraction temperature and extraction time commonly have a positive impact on the extraction efficiency of thermostable plant compounds. For example, increasing the extraction temperature from 40 to 90 °C and the extraction time from 1 to 4 h increased the extraction yield of polysaccharides of Gynura bicolor leaves [26], while increasing the extraction temperature from 30 to 80 °C and the extraction time from 20 to 180 min increased the tea protein extraction rate of tea residues [27]. Moreover, Yuan et al [28] revealed a similar result for the optimization of polysaccharides from wild Russula griseocarnosa, where increasing the extraction temperature from 50 to 90 °C and extraction time from 1 to 5 h increased extraction yield of said polysaccharides.…”

Optimization of dynamic maceration of Clausena anisata (Willd.) Hook. f. ex Benth. leaves to maximize trans-anethole content

et al. 2021

Trans-anethole possesses several biological and pharmacological effects. It is also used as masking agent in household products and as a flavoring agent in food. Clausena anisata (Willd.) Hook. f. ex Benth. leaves are reported as a source of trans-anethole that makes their anise-like odor. This work sought to optimize the dynamic maceration of C. anisata leaves to maximize the trans-anethole content. The circumscribed central composite experimental design was applied to investigate the effects of extraction temperature and time on extraction yield, trans-anethole content in the extract, and trans-anethole content in the plant raw material. The results showed that the extraction yield was high when C. anisata leaves were extracted over a long extraction time, while the extraction temperature had a lesser effect on the extraction yield. Trans-anethole content in the extract and plant raw material determined using a linear, specific, precise, and accurate HPLC method was high when a medium extraction temperature with a short extraction time was used. The optimal condition that maximized trans-anethole content involved an extraction temperature of 61.8 °C and an extraction time of 12.9 min, respectively. The percentage error of the prediction conducted by computer software was low, suggesting that the prediction was highly accurate. In conclusion, the optimal condition of dynamic maceration obtained from this work could be used as a guide for maximizing trans-anethole content from C. anisata leaves.

Despite the progressive reports on potential pharmacological properties of G. procumbens, the importance of agronomic requirements to produce high yields and phytochemical content that may vary due to environmental variations are often overlooked. Therefore, this study was conducted to examine the effects of N, K and ER interaction on the growth and phytochemical content of G. procumbens. The study was a three-factorial experiment; two rates of N and K, four rates of ER and three H time. The treatments have affected plant growth and phytochemical content significantly (p≤0.05) with stronger effect on physiology and biochemical attributes (p≤0.01). The study has shown discrete effect on growth, physiology, and phytochemicals content with N0K30>N90K0 and ER 75>50>100>25% treatment. The highest and lowest yield of plant biomass and phytochemical were observed under N0K30(70) and N90K0(25), respectively. The results have shown that the interaction and effect of treatments are highly significant (p≤0.0001) in Cond, CNB, TChlC, TPrC and TFC analysis, (p≤0.05) in NoL, CF and PWP, and not significant in TLA, Photo, TCC, TLC and TPC. The 75% ER has produced significant output of biomass as well as phytochemical content. The study also showed that low rate of N, moderate rate of K with 75% ER have produced high biomass as well as phytochemical content. Meanwhile, caffeic acid and kaempferol were demonstrated as the lead secondary metabolite compounds in this study.
