Abstract
BACKGROUND Spilanthes filicaulis (Schumach. & Thonn.) C. D Adam is a shrubby plant of the Asteraceae family that has medicinal benefits for the pharmaceutical and cosmetic industries. PURPOSE The purpose of this study was to assess the effectiveness of Spilanthes filicaulis leaf extract in a streptozotocin (STZ)-induced rat model and the associated signaling pathways. METHODS A sample of 25 male Wistar rats was randomly assigned to groups I, II, III, IV, and V. Each group included five animals, i.e., control rats, diabetic control rats, diabetic rats treated with metformin, and diabetic rats treated with 150 mg/kg/bw and 300 mg/kg/bw of the methanolic extract of S. filicaulis leaves (MESFL). Treatment was administered for 15 successive days via oral gavage. After 15 days, the rats were evaluated for fasting blood glucose (FBG), glycated hemoglobin (HbA1c), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), reduced glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (MDA), hexokinase, and glucose-6-phosphatase activities. Gene expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2), peroxisome proliferator-activated receptor gamma (PPAR-γ), kelch-like ECH-associated protein 1 (Keap1), protein tyrosine phosphatase 1B (PTP1B) and the antiapoptotic protein caspase-3 were examined. RESULTS MESFL was administered to diabetic rats, and changes in body weight, fasting blood glucose (FBG) and HbA1c were restored. Furthermore, in diabetic rats, S. filicaulis significantly reduced the levels of triglycerides (TGs), total cholesterol (TC), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) and significantly increased HDL. S. filicaulis improved ALT, AST, and ALP enzyme activity in diabetic rats. MDA levels decreased considerably with increasing activity of antioxidant enzymes, such as GST, SOD, CAT and GSH, in diabetic liver rats treated with S. filicaulis. Diabetic rats treated with MESFL and metformin exhibited upregulated mRNA expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and peroxisome proliferator-activated receptor gamma (PPAR-γ). Kelch-like ECH-associated protein 1 (Keap1) and protein tyrosine phosphatase 1B (PTP1B) mRNA expression in the liver was downregulated in diabetic rats treated with MESFL and metformin. In addition, MESFL downregulated the mRNA expression of caspase-3 in diabetic rats. CONCLUSION It can be concluded from the data presented in this study that MESFL exerts a protective effect on diabetic rats due to its antidiabetic, antioxidant, antihyperlipidemic and antiapoptotic effects and may be considered a treatment for T2DM.

Possibilities of valorization of Gnetum spp leaves in modern gastronomy: Production and characterization of new vegetable tarts and salads. Heliyon 2023; 9:e18542. [PMID: 37576241 PMCID: PMC10412999 DOI: 10.1016/j.heliyon.2023.e18542] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 07/14/2023] [Accepted: 07/20/2023] [Indexed: 08/15/2023] Open
Abstract
Gnetum spp is a green creeper plant abundantly found in the Central African forests. Their leaves are eaten as vegetable by inhabitants. In order to valorize this vegetable in modern gastronomy, a survey was carried out in three towns of Cameroon to evaluate its importance in the feeding habits. The leaves were also sliced in two different forms, precooked, spin-dried and used for Gnetum tarts and salads production. 50, 100 and 150 g of thin sliced precooked leaves were used to prepare three salads and three tarts, keeping the other ingredients constant. Three additional tarts were prepared similarly using thinnest sliced precooked leaves. The final products were analyzed in terms of physiochemical, nutritional and sensorial properties. More than 96.9% of people investigated eat Gnetum leafy vegetables at least once per month. The survey study indicates that the transformation of Gnetum is mostly done by people within the age of 20 to 40 years old. Results of the physicochemical analyses showed that the total protein, lipid and carbohydrate contents increased in general with the increasing of the Gnetum leaf quantities used for preparation. The crude fiber contents of salads and tarts ranged from 52.00 ± 0.68 to 62.66 ± 1.26 and 29.33 ± 0.67 to 33.66 ± 0.47 g/100 g DW respectively. They were positively correlated with the quantity of Gnetum leaves used. The total phenolic contents, also increased significantly (p < 0.05) with the quantity of Gnetum leaves, from 182.45 ± 1.69 to 493.52 ± 2.10 mg/100 g DW for the salad and from 86.69 ± 4.08 to 283.21 ± 6.79 mg/100 g DW for the tart. The calculated energy density of tarts and salads permitted to classify these food products as low and high energy density foods respectively. The nutritional densities of produced tarts oscillated from 0.27 to 0.3 and that of salads from 0.58 to 0.71. With their nutritional values and the significant amount of fibers, Gnetum tarts and salads could be good new recipes to valorize the Gnetum leafy vegetables.

Amino acid composition, mineral profile, free radical scavenging ability, and carbohydrase inhibitory properties of Moringa oleifera seed globulin, hydrolysates, and membrane fractions. J Food Biochem 2022; 46:e14131. [PMID: 35322904 DOI: 10.1111/jfbc.14131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2021] [Revised: 02/14/2022] [Accepted: 02/23/2022] [Indexed: 12/29/2022]
Abstract
The nutritional-amino acid profile and mineral element of Moringa oleifera seed globulin (GLO) and its hydrolysates as well as the in vitro bioactive properties-antioxidant, alpha-amylase, and alpha-glucosidase inhibition of the GLO, hydrolysates, and membrane fractions were reported. The results showed that M. oleifera contained significant amounts of essential amino acids (EAA), which are more than the minimum required by the Food and Agricultural Organization for children, except for tryptophan, which was the limiting amino acid. However, hydrolysis mostly led to a reduction in the contents of the EAA. While the process of hydrolysis and the subsequent membrane fractionation produced peptides with improved activities in 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid radical scavenging ability and oxygen radical absorbance capacity, this process produced no activities in superoxide radical scavenging ability, α-amylase, and α-glucosidase inhibitory potentials of some of the hydrolysates and peptides fractions. In summary, M. oleifera seed peptide fraction (<3 kDa) from the alcalase-derived hydrolysate contains potent antioxidants but relatively low in vitro antidiabetic properties. PRACTICAL APPLICATIONS: Several studies have established the ability of proteins, including hydrolysate and peptide fractions to provide some bioactive properties such as antioxidant, antidiabetic, anti-inflammatory among others. However, because protein functionalities are influenced by several factors such as the source, type, processing method employed among others, research has continued to evaluate the bioactivities of proteins under different conditions. In this study, therefore, we reported the impact of processing methods (hydrolysis, enzyme type, and peptide size) on the nutritional, antioxidant, and in vitro antidiabetic properties of M. oleifera seed globulin, its hydrolysates, and membrane fractions. This information plays an important role in the further exploitation of M. oleifera seed proteins in the development of functional foods and nutraceuticals.

Abstract
Abstract
The bioactive compounds contributing to aroma and natural antimicrobial potential of oil from Dacryodes edulis seed can be harnessed in food industries as food preservatives. This study therefore, reveals the preservative effect and organoleptic property of meat and fish preserved with oil from D. edulis seed. Proximate and mineral analysis of oil were carried out using standard methods. Preservative quality of oil on fish and meat was investigated at 4°C and 37°C. Organoleptic property of preserved fish and meat was determined using trained panellists. Fat, protein, carbohydrates, crude fibre, ash and moisture content of oil from D. edulis seed are 55.7%, 18.7%, 10.8%, 7.1%, 4.6% and 3.1%, respectively. Potassium (106.5 µg/g) and phosphorous (102.5 µg/g) have the relatively highest values compared (p<0.05) to other minerals like zinc, iron, calcium, magnesium, and sodium. Better preservative property of oil was observed on fried fish and meat kept at 4°C with no microbial growth. The highest microbial load (3.95 × 106 cfu/g) occurred in fresh chicken coated with oil from D. edulis seed after 7 days of preservation. Fish and meat fried with oil from D. edulis seed were well accepted (9.00) than those fried with groundnut oil (3.50). Oil from D. edulis seed is an edible oil that can be utilized as alternative vegetable oil with natural preservatives and embedded nutrients.

Abstract
The genus Parkia (Fabaceae, Subfamily, Mimosoideae) comprises about 34 species of mostly evergreen trees widely distributed across neotropics, Asia, and Africa. This review aims to provide an overview of the current status of the species from the genus Parkia in terms of its relationship between its phytochemistry and medical uses. Comprehensive information on Parkia species was retrieved from electronic databases, which were Web of Science, ScienceDirect, PubMed, and Google Scholar. This review identified nine species from genus Parkia with properties of medicinal use. They are used traditionally to treat several ailments, such as diabetes, diarrhea, wounds, hypertension, cough, chronic piles, conjunctivitis, and measles. The most common species studied are P. biglobosa, P. speciosa, P. javanica, P. bicolor, P. biglandulosa, P. filicoidea, and P. clappertoniana. A considerable number of secondary metabolites, such as terpenoids, phenolic acids, flavonoids (aglycone and glycosides), and numerous volatile compounds have been identified in this genus, which are responsible for their diverse pharmacological activities. Their extracts, pure compounds and seed lectins have been reported for their anticancer, antimicrobial, antihypertensive, antiulcer, antidiabetic, anti-inflammatory, antioxidant, antimalarial, hepatoprotective, and antidiarrheal activities. The information gathered in this review might be of help for future studies in terms of the current knowledge on the link between the phytochemical components and medicinal uses. This could facilitate more discoveries on its potentials particularly in the pharmacological characteristics and potential to be developed into modern medicines.

Abstract
There is increasing evidence that nutrient differences observed among crop varieties or animal breeds belonging to the same species are sometimes greater than differences between species. Parkia biglobosa is an important tree species that provides edible products and income to rural households in West Africa. To better understand intra-species nutrient variability of P. biglobosa edible products, a review on the nutrient content of its pulp and seeds (raw and fermented) was conducted. Google scholar and the keywords "P. biglobosa" AND "nutrition" were used to screen the available literature from 1980 onwards, and the Zotero software was used to manage references. A step-wise assessment of titles, abstracts and full papers, led to a selection of 69 papers from which data were retrieved following FAO INFOODS guidelines. After data harmonization and quality checks, 42 papers were retained and used to extract data to populate a nutrient database. Despite an apparent abundance of nutrient analyses focused on P. biglobosa's edible products, the quality of data available was poor and very few authors presented additional information, such as soil characteristics, climate, maturity at harvest, etc. that could influence the nutritional content of the products. Many data gaps remain. The present study will stimulate further investigations into nutrient composition of P. biglobosa products and ultimately will contribute to selecting nutritionally "+" trees for multiplication and/or domestication of the species.

Abstract
PURPOSE The current study aimed to determine the antidiabetic effects of leaf extract of Ficus asperifolia in streptozotocin-induced diabetic rats. METHODS A total of ninety-five (95) adult rats were used for the experiment. The whole study protocol was divided into three sets of individual experiments. The animals were divided randomly into seven groups of five rats each. The rats were given a diet supplemented with 50 g high fat to 50 g vital feeds for two weeks. The study lasted 28 days with daily administration and weekly blood glucose and body weight check. At the end of the experiment protocol, the rats were fasted overnight and were anesthetized. Blood was collected via cardiac puncture from each animal for biochemical analysis. Metglim 3.38 mg/kg bodyweight was used as positive control. Diabetes was induced using streptozotocin (35 mg/kg in 0.1 M phosphate-buffered saline) intraperitoneally for 5 days. Phytochemicals were analyzed in both extract and fractions. RESULTS Phytochemical screening revealed the presence of alkaloids, saponins, flavonoids, glycosides, tannins, carotenoids, terpenes, and steroids in both extract and fractions. Proteins, carbohydrates, and fats were detected by systematic molecular analysis. Fraction 1 of plant extracts prevented glucose-induced hyperglycaemia 30 min' post glucose load in all rats. Streptozotocin treatment caused a significant increase (p˂0.05) in blood sugar, total cholesterol, triacylglycerol, low-density lipoproteins and a significant (p˂0.05) decrease in food intake, body weight and high-density lipoproteins in diabetic rats. CONCLUSION Treatment with the extract significantly improved the derangements caused by streptozotocin. These results suggest that the leaf extracts of Ficus asperifolia could serve as a potential treatment for diabetes therapy.

Abstract
Annonamuricata plant parts possess a broad range of medicinal and biological properties. This research compared the chemical composition and antioxidant properties of Annonamuric at aparts. Proximate, mineral, total phenol and total flavonoid content as well as invitro antioxidant activity were examined. Results revealed the leaves contained significantly(p<0.05) higher composition of moisture (8.69±0.22%), ash (4.60±0.02%), protein (14.53±0.11%), crude fat (10.28±0.03%),chromium (0.38±0.05 mg/100g), nickel (1.75±0.04mg/100g), total phenol (1.01±0.03mgpyrocatechol/mL) and total flavonoid (1.12±0.03mgGAE/mL)compared to the respective values for root. Carbohydrate (9.29±0.24%), lead (0.13±0.02mg/100g) and cobalt (1.93±0.02mg/100g) composition was significantly lower(p<0.05) in the leaves compared to the respective compositions in the root. The leaf and root extract exhibited a concentration-dependent increase in hydroxyl radical scavenging activity with no observable(p<0.05)difference in their EC50 value. This study suggests the leaves of A. muricata found in Covenant University had better chemical composition when compared to the root. Nonetheless, these plant parts may be further exploited for not only their nutritive composition and mineral content but also a natural source of antioxidant agents.

Abstract
Therapies directed towards controlling hyperglycemia, the hallmark of type-2 diabetes mellitus, go a long way in managing diabetes and its related complications. Reducing glucose level through the inhibition of the relevant carbohydrate hydrolyzing enzymes is one among many routes in the management of diabetes. This study investigates the in vitro enzyme inhibitory and antioxidant properties of solvent-partitioned fractions of Spondias mombin and Mangifera indica leaves; which are used extensively in the treatment of diabetic patients locally. The leaves of S. mombin and M. indica were extracted with methanol and fractionated to obtain n-hexane (HF), ethyl acetate (EAF), n-butanol (BF), and aqueous (AF) fractions successively. The α-amylase and α-glucosidase inhibitory activities of fractions of S. mombin and M. indica leaves were investigated while the antioxidant activity of each fraction was analyzed using iron chelating and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline)-6-sulphonic acid) radical scavenging assay. Our findings indicated that the ethyl acetate fraction of M. indica leaves contained a considerably higher (p < 0.05) amount of total phenolic, flavonoids, metal ion, and ABTS radical scavenging activity than the ethyl acetate fractions of S. mombin. Furthermore, the ethyl acetate fraction of M. indica had a considerably higher (p < 0.05) inhibitory effect on α-glucosidase (IC50 = 25.11 ± 0.01 μg mL-1), and α-amylase (IC50 = 24.04 ± 0.12 μg mL-1) activities than the S. mombin fraction. Hence, the inhibitory activities of S. mombin and M. indica leaves suggest that they are a potential source of orally active antidiabetic agents and could be employed to formulate new plant-based pharmaceutical and nutraceutical drugs to improve human health.
