“…This result is in agreement with those reported by Tejasari [15] (10.2%), Tewtrakul and Subhadhirasakul [22] (11.4% and 10.4%), and Ahui et al [26] (11%). However, it is higher than those obtained by Mascolo et al [6] (2.8%), Alfaro et al [27] (3.6, 3.2, and 0.27%), and Goyal and Kadnur [28] (4.6 and 4.3%).…”

Three different biochemical test systems were chosen based on their solubility to study the antioxidant activity of ginger extracts. Reducing power and DPPH . scavenging activity tests were considered to produce hydrophilic environments and the H 2 O 2 test was considered as creating a lipophilic environment. The average yields were 10.23 ± 1.02% and 0.48 ± 0.19% for oleoresin and essential oil, respectively. The content of total phenols was 67.6 ± 1.08 mg GAE/g of dry extract. In terms of EC 50 , in hydrophilic environment standards, it showed the highest effects compared to ginger extracts, with oleoresin presenting more activity than essential oil. In contrast, except for quercetin, essential oil showed the best scavenging activity in inhibiting H 2 O 2 compared to all other antioxidants. The present work demonstrated that, when using reducing power, DPPH· free radical scavenging and H 2 O 2 scavenging assays, the same ginger extracts exhibit different antioxidant activities, which were affected not only by the extract itself but also by the chemical environment (hydrophilic/lipophilic).

“…After the complete exhaustion of plant cells, the microwave power did not show any significant effect on concentration of active constituents (Alfaro et al 2003). Still, if the herb was exposed to higher power it would deteriorate the chemical structure of active compound to cause decrease in its yield (Hao et al 2002).…”

Context: Marrubium vulgare Linn (Lamiaceae) was generally extracted by conventional methods with low yield of marrubiin; these processes were not considered environment friendly. Objective: This study extracts the whole plant of M. vulgare by microwave assisted extraction (MAE) and optimizes the effect of various extraction parameters on the marrubiin yield by using Central Composite Design (CCD). Materials and methods: The selected medicinal plant was extracted using ethanol: water (1:1) as solvent by MAE. The plant material was also extracted using a Soxhlet and the various extracts were analyzed by HPTLC to quantify the marrubiin concentration. Results: The optimized conditions for the microwave-assisted extraction of selected medicinal plant was microwave power of 539 W, irradiation time of 373 s and solvent to drug ratio, 32 mL per g of the drug. The marrubiin concentration in MAE almost doubled relative to the traditional method (0.69 ± 0.08 to 1.35 ± 0.04%). The IC 50 for DPPH was reduced to 66.28 ± 0.6 lg/mL as compared to conventional extract (84.14 ± 0.7 lg/mL). The scanning electron micrographs of the treated and untreated drug samples further support the results. Discussion and conclusion: The CCD can be successfully applied to optimize the extraction parameters (MAE) for M. vulgare. Moreover, in terms of environmental impact, the MAE technique could be assumed as a 'Green approach' because the MAE approach for extraction of plant released only 92.3 g of CO 2 as compared to 3207.6 g CO 2 using the Soxhlet method of extraction.

“…However, previous work has often focused on the use organic solvents to extract the essential oil contained in dried ginger [21]. Not only would the preparation of the ginger incur additional processing costs in a commercial system, but the solvents used can be costly and harmful to the environment.…”
