“…However, the antioxidant abilities of cassava leaves, ceara rubber leaves, Chinese Albizia leaves, and lophatheri leaves, while still lower than the previous studies, were found to have high antioxidant activity [12,24,27,66]. Differences between the present study results and those reported in the literature can be due to variations in the concentration and type of solvent, extraction method, amount of total polyphenol and total flavonoid content, environmental factors, and treatment during plant growth [67][68][69][70].…”

“…The ability of plants to inhibit free radical activity is due to various phytochemical substances, mainly total polyphenol content and total flavonoid content [69]. Polyphenols have mechanisms to provide hydrogen donors, heavy metal chelators, and electrons or increase the response of antiradical cells to reactive oxygen species [71][72][73].…”

Identification of antinutritional, antioxidant, and antimicrobial activity of plants that cause livestock poisoning in Bojonegoro Regency, Indonesia

Background and Aim: The utilization of cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves from Bojonegoro Regency has led to the poisoning of livestock due to antinutritional factors. Nevertheless, the plants are known to have bioactive components and potential antioxidant and antibacterial activity if appropriately processed. This study aimed to determine the antinutritional compounds as well as the antioxidant and antibacterial potential of these plants responsible for livestock poisoning in the Bojonegoro Regency. Materials and Methods: Extraction was performed by the maceration method using 70% (v/v) ethanol solvent. The samples were analyzed qualitatively to determine the presence of tannins, alkaloids, oxalates, cardiac glycosides, and cyanogenic glycosides. The antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl method, while the antimicrobial activity was assessed by different testing concentrations (125, 250, and 500 mg/mL) against Staphylococcus epidermidis, Staphylococcus aureus, and Escherichia coli. Results: The ethanolic extract of the plants was found to contain antinutritional tannins, alkaloids, cardiac glycosides, and cyanogenic glycosides suspected of causing livestock poisoning. Despite the presence of these antinutrients, all extracts also had antioxidant and antibacterial potential. Cassava peels and sweet potato leaves had the highest antioxidant activity, whereas Chinese Albizia leaves had the most potent antibacterial activity. Conclusion: Cassava leaves and peels, ceara rubber leaves, sweet potato leaves, Chinese Albizia leaves, and lophatheri leaves obtained from Bojonegoro Regency and used as agricultural waste contain antinutritional factors but also possess potentially effective antioxidant and antimicrobial components.

“…In review, it is easy to see that the plant extracts currently used in the treatment of chronic diabetic ulcers barely exhibit antimicrobial effects. However, from the literature, we found that tannic acid (TA) ( Chung et al, 1998 ; Wang et al, 2022 ), paeoniflorin (PF) ( Bai et al, 2021 ), calendula extract ( Abudunia et al, 2017 ), and myricetin (MY) ( Liu C et al, 2021 ) also have antibacterial effects. In addition to existing plant extracts that are already used in hydrogels, studies have shown that plant extracts, such as extracts from Curcuma longa (curcumin) ( Saranya et al, 2018 ; Jirofti et al, 2021 ), Rubus chamaemorus leaves ( Thiem and Goslinska, 2004 ), and peony flowers (Vitex pinnata) ( Shafie et al, 2020 ), can exhibit powerful antibacterial abilities when applied to wounds.…”

Due to recalcitrant microangiopathy and chronic infection, traditional treatments do not easily produce satisfactory results for chronic diabetic ulcers. In recent years, due to the advantages of high biocompatibility and modifiability, an increasing number of hydrogel materials have been applied to the treatment of chronic wounds in diabetic patients. Research on composite hydrogels has received increasing attention since loading different components can greatly increase the ability of composite hydrogels to treat chronic diabetic wounds. This review summarizes and details a variety of newly loaded components currently used in hydrogel composites for the treatment of chronic diabetic ulcers, such as polymer/polysaccharides/organic chemicals, stem cells/exosomes/progenitor cells, chelating agents/metal ions, plant extracts, proteins (cytokines/peptides/enzymes) and nucleoside products, and medicines/drugs, to help researchers understand the characteristics of these components in the treatment of diabetic chronic wounds. This review also discusses a number of components that have not yet been applied but have the potential to be loaded into hydrogels, all of which play roles in the biomedical field and may become important loading components in the future. This review provides a “loading component shelf” for researchers of composite hydrogels and a theoretical basis for the future construction of “all-in-one” hydrogels.

“…The ability of each L. gracile extract to reduce Fe (III) was assessed using a previously described method with slight modifications [36,37]. For this assay, an aliquot (400 μL) of phosphate buffer (pH 3.6) and FeCl 3 (400 μL, 20 mmol/l) were added to a tube and incubated at 37 • C for 15 min.…”

A combinative method using high-performance liquid chromatographyelectrochemical detection for fingerprinting and quantitative analysis was developed and successfully applied for the quality evaluation of Lophatherum gracile Brongn leaves collected from 21 geographical locations in China. In the fingerprint analysis, 18 common peaks were observed among the 21 samples, and 10 peaks were identified. Simultaneous quantification of the 10 components was conducted to interpret the variations in these compounds among the L. gracile Brongn leaves originating from different geographical locations. The correlation between the chromatograms and the antioxidant activities of the samples was further studied. The results indicated a linear correlation between the antioxidant activity and the total common peak areas of the fingerprints obtained by high-performance liquid chromatographyelectrochemical detection. Importantly, it was found that high-performance liquid chromatography-electrochemical detection fingerprinting can not only determine the quantities of individual components present in such samples but also evaluate the antioxidant activities of the samples. The developed method is a valuable reference for the further study and development of L. gracile Brongn.
