“…The extraction methods show similar yields for each plant part. Several studies reported that the extraction yields are not directly linked with biological activity as well as chemical composition (Anokwuru et al., 2018; Braga et al, 2016; Do et al., 2014). Furthermore, plants have complex matrices containing different compounds decorated with diverse chemical groups that could be extracted by the solvents used.…”

Viscum album L. (Mistletoe) is one of the most famous plants in many countries utilized for several purposes. The current study aimed to describe chemical profiles and biological activities of homogenizer‐assisted extract (HAE) and ultrasound‐assisted extract (UAE)) of V. album parts (leaf, fruits, and seeds). Antioxidant (radical scavenging, reducing power, metal chelation, and phosphomolybdenum assays) and enzyme inhibitory properties (cholinesterases, amylase, glucosidase, and tyrosinase) were selected for biological evaluation. Chemical profiles were studied by HPLC‐MS/MS and 32 compounds were identified in the extracts; caffeoylquinic acids and its derivatives, dimethylated flavonoids were the most significant compounds. Generally, the leaf extracts exhibited the best antioxidant and enzyme inhibitory effects in our tests. Multivariate analysis was performed to obtain more information for these data, then strong correlations between total bioactive compounds and tested parameters were observed. The present findings encourage us to further investigate V. album as a potential candidate for pharmaceutical and nutraceutical applications. Practical applications Viscum album L. commonly called European mistletoe is a woody perennial shrub growing on coniferous trees with lathery leaves, small flowers, and white berries. It belongs to the Santalaceae R. Br. family from Europe and western/southern Asia. Traditional medicine recognizes mistletoe as a folk remedy to manage inflammation, hypertension, ulcers, and other diseases due to the presence of different bioactive compounds, among them mistletoe lectins and viscotoxins. Recent studies documented the possible therapeutic applications of Viscum extracts in association with cancer's therapy leading to improvements in health and patient's quality of life. Thus, this work gives novel data regarding the phytochemical characterizations and antioxidant/enzymatic inhibitor activities of different types of extracts from seeds, leaves, and fruits of Viscum L. obtained by homogenizer‐assisted and ultrasound‐assisted techniques, in order to increase the data set of potential applications in medicine.

“…The results of different experimental runs for both HAE and UAE processes are given in the Appendix. The relationship between extraction yield, polyphenol content, and antioxidant activity may reveal the true biological value of plant extracts (Braga et al, ); therefore, these parameters were considered as response variables in this study. The TEY (or EY), TPC (or TPY), and IC 50 in the extracts from HAE process (Step 1) were ranged from 8.74% to 17.52% (or 1.1% to 2.43%), 73.29 to 149.24 mg GAE/g of extract DW (or 19.2 to 38.08 mg GAE/g of leaves DW), and 940.25 to 5,161.79 μg/ml, respectively.…”

The conditions used in heat‐ and ultrasound‐assisted extraction (HAE and UAE, respectively) of polyphenols from rosemary leaves were optimized using response surface methodology. The optimum HAE conditions included an extraction time of 132.80 min, temperature of 70°C, and 20:1 liquid‐to‐solid ratio, resulting in the maximum total extraction yield (TEY, 17.80%) or total polyphenol content (TPC, 147.56 mg GAE/g of extract DW), and minimum IC50 (994.68 μg/ml); the maximum TEY (20.82%) or TPC (185.16 mg GAE/g of extract DW), and minimum IC50 (805.84 μg/ml) in the UAE process were obtained using optimum conditions, including time of 12.60 min, power of 200 W, and ethanol concentration of 56.26%. The lowest IC50 (787.70 μg/ml) was recorded using a solvent mixture of water and ethanol (56%) in the HAE procedure similar to the amount determined for the BHT antioxidant (714.79 μg/ml), thus confirming the efficiency of the extraction procedure. Practical applications The antioxidant properties of rosemary leaves are well characterized; hence, this plant’s extract is approved as the only accepted natural food antioxidant in the EU. Generally, the extraction of active compounds from rosemary leaves is performed by the HAE method. However, it is recommended to use sustainable technologies, such as UAE. The optimization of both conventional and UAE of polyphenols from rosemary leaves has not been studied in the literature. Therefore, the purpose of the present study was to introduce the optimal conditions of the HAE and UAE methods required to obtain maximum extraction efficiency of polyphenol compounds from rosemary leaves, and then was to compare possible procedures so that a comprehensive method to be developed.

“…This variation of the result was due to the climatic condition of the states and the soil nature of the states. Many literatures revealed that plant biomass depends on the soil nature, soil fertility as well as climatic condition and nature of solvent used for the extraction (Anwar et al, 2013;Braga et al, 2016, Das et al, 2016. Thereafter, yield of the extract directly proportional with the plant biomass (Das and Tribedi, 2015).…”

A fern, Phlebodium decumanum (Willd.) J.Sm. (PD) belongs to the family Polypodiaceae. It is a creeping, densely hairy or scaly rhizome bearing fronds at intervals along its length. It is native to tropical and subtropical regions of the America. The present study was investigated to establish the presence of phytoconstituents in leaf samples collected from three different geographical zones (Bengaluru, Nasik, and Munnar) and their impact on antioxidant and anthelmintic activity. Aqueous and methanol leaf extracts were used as solvent for extraction (conventional Soxhlet method) and results were compared to established novel application of fern species. Results revealed presence of alakloids, polyphenols, terpenoids, flavonoids, etc., upon various chemical tests. Thereafter, antioxidant study was established with DPPH and FRAP assay method. The IC 50 value for methanol extract showed higher (210.24 µg/ml) for Munnar sample than the other two samples. An anthelmintic activity was determined by compared with Albendazole standard (25 mg/ml). Results revealed significant a nthelmintic activity (p<0.01 ) for methanol extra ct of Munnar sample in terms of the time taken for paralysis and death study.
