“…The skeletal vibrations of the benzene ring were at 1,654, 1,558, 1,506, 1,457 cm −1 (Jeyakumar and Narayanasamy, 2020). The peak 1,256 cm −1 was attributed to aromatic ether (Szymulanska-Ramamurthy et al, 2017). The asymmetric stretching vibration of C-O-C was at 1,174 cm −1 (Dehghani et al, 2020).…”

Recently, natural resources have attracted considerable interest for their applications in food security and human health problems. Traditional natural spices, such as star anise and black pepper, played important roles in the pharmaceutical and food industries due to their strong pharmacological activity, antioxidant potential and rare complications. In order to achieve biomasses from the natural product with multiple bioactivities, we developed the multistage extraction method to extract and separate various bioactive compounds from these natural plants. Our work demonstrated that various bioactive-rich extractives were achieved using steam distilled- or oxidative-extraction methods with high extraction yields and purity. Furthermore, the extractives in each step can be used not only as bioactive compounds, but also as a resource to further prepare different derivatives during the next extractive step, providing biomass-saving to a great extent. The extractives obtained with high yields and purities (>82%) were identified by 1H NMR, 13C NMR, FTIR, UV-vis, fluorescence spectroscopy, and high-performance liquid chromatography (HPLC). Moreover, these biomasses display potent antibacterial activities against some types of microorganisms such as S.aureus, S.pyogenes, E.coli, and S.typhi with a lowest MIC of 400 μg/ml for the development of antibacterial agents, significant antioxidant activity as the natural antioxidant for enhancing food shelf-life, and excellent anticancer activity that induces significant cancer cell apoptosis. This work showed the different multistage extracts from natural products, which enable them to be applied in the fields of the pharmaceutical industry and the food industry.

“…Several studies have illustrated that essential oils, terpenes and lignans from Illicium species, such as I. verum , I. griffithii , I. wardii , I. angustisepalum and I. simonsii , have potent antimicrobial activity [ 19 , 20 , 21 , 22 , 23 ]. To explain and confirm the antibacterial activity of I. simonsii , bioassay-guided fractionation of the ethanol extract of I. simonsii resulted in the isolation of three new natural compounds ( 1 , 3 and 5 ) and eight known compounds ( Figure 1 ), in which compounds 3 , 6 and 7 are responsible for the antibacterial activity.…”

Two undescribed ether derivatives of sesquiterpenes, 1-ethoxycaryolane-1, 9β-diol (1) and 2-ethoxyclovane-2β, 9α-diol (3), and one new monoterpene glycoside, p-menthane-1α,2α,8-triol-4-O-β-D-glucoside (5), were obtained, together with eight known compounds from the stems and leaves of I. simonsii. Their structures were elucidated by spectroscopic methods. Compounds 1–11 were evaluated for their potency against Staphylococcus aureus and clinical methicillin-resistant S. aureus (MRSA). Among them, compound 3 was weakly active against S. aureus (MIC = 128 μg/mL), and compounds 6 and 7 exhibited good antibacterial activity against S. aureus and MRSA (MICs = 2–8 µg/mL). A primary mechanism study revealed that compounds 6 and 7 could kill bacteria by destroying bacterial cell membranes. Moreover, compounds 6 and 7 were not susceptible to drug resistance development.

“…For detecting the presence of phytochemicals the initial concentration of extracts selected was 10mg/ml and 10µl sample was loaded on to the TLC sheets. Extracts were loaded on Silica gel 60 F254 TLC aluminium sheets (5×7.5 cm) (Merck) were used to perform analysis (Aliyu, 2011;Bhole, 2015;Szymulanska-Ramamurthy, 2017). Details of solvent systems, developing reagents and positive observations are as mentioned in the table below and are different for according to phytochemical.…”

Present study investigates antimicrobial, antioxidant activity and phytochemical profiling of alcoholic extracts of whole fruit of Actinidia deliciosa (kiwi fruit). Cold and hot extracts of whole Actinidia deliciosa fruit prepared in methanol and ethanol and their different concentrations were tested against common nosocomial infections and human pathogens of skin, gestrointestinal tract and upper respiratory tract. Extracts were evaluated for their phytochemical constituents and antioxidant activity. Cold ethanolic extract of whole kiwi fruit has good antimicrobial activity as it inhibited the growth of almost all test organisms at concentration less than 20 mg/ml. Cold ethanolic extract was also found to be effective against Candida albicans at a concentration of 38.33 mg/ml. Antioxidant activity was examined by DPPH radical scavenging assay, highest antioxidant activity was displayed by cold methanolic extract. The qualitative phytochemical analysis of the extracts revealed the presence of alkaloids, flavonoids, saponins, cardiac glycosides, tannins and terpenoids in whole fruit of Actinidia deliciosa.
