“…French maritime pine bark extracts have also shown potent alpha-glucosidase inhibitory activity compared to green tea extract and acarbose, and procyanidin oligomers were found to be responsible for this activity (Schäfer and Högger 2007 ). Some of the identified plants in this review exhibiting alpha-glucosidase inhibitory activity are already used as food or ingredient food for thousands of years in the human diet such as the fruit (acorn) of the Quercus species (Ómez et al 2017 ) and are likely to be safe candidate for the development of dietary supplements. In addition to alpha-glucosidase inhibition, whole plant preparations contain a wide range of active compounds with anti-inflammatory and antioxidative activities that can improve diabetes health outcomes.…”

A review of alpha-glucosidase inhibitors from plants as potential candidates for the treatment of type-2 diabetes

Diabetes mellitus is a multifactorial global health disorder that is rising at an alarming rate. Cardiovascular diseases, kidney damage and neuropathy are the main cause of high mortality rates among individuals with diabetes. One effective therapeutic approach for controlling hyperglycemia associated with type-2 diabetes is to target alpha-amylase and alpha-glucosidase, enzymes that catalyzes starch hydrolysis in the intestine. At present, approved inhibitors for these enzymes are restricted to acarbose, miglitol and voglibose. Although these inhibitors retard glucose absorption, undesirable gastrointestinal side effects impede their application. Therefore, research efforts continue to seek novel inhibitors with improved efficacy and minimal side effects. Natural products of plant origin have been a valuable source of therapeutic agents with lesser toxicity and side effects. The anti-diabetic potential through alpha-glucosidase inhibition of plant-derived molecules are summarized in this review. Eight molecules (Taxumariene F, Akebonoic acid, Morusin, Rhaponticin, Procyanidin A2, Alaternin, Mulberrofuran K and Psoralidin) were selected as promising drug candidates and their pharmacokinetic properties and toxicity were discussed where available.

“…Powder of gallnuts of Q. infectoria is used to restore the elasticity of the uterine wall, as well as to treat aphthous ulcers [ 31 , 39 ]. The fruit (acorn) of the Quercus species is considered as a nutritionally rich source of energy (source of carbohydrates, proteins, and fat), justifying their use as food or ingredient food for thousands of years in the human diet such as in bread production or as an ingredient for making coffee [ 40 – 42 ]. The acorns of the various species of oak are widely used in curing diarrhea, laryngopharyngitis diseases, menorrhagia, obesity, and stomach ulcers [ 8 , 9 ].…”

Quercus species, also known as oak, represent an important genus of the Fagaceae family. It is widely distributed in temperate forests of the northern hemisphere and tropical climatic areas. Many of its members have been used in traditional medicine to treat and prevent various human disorders such as asthma, hemorrhoid, diarrhea, gastric ulcers, and wound healing. The multiple biological activities including anti-inflammatory, antibacterial, hepatoprotective, antidiabetic, anticancer, gastroprotective, antioxidant, and cytotoxic activities have been ascribed to the presence of bioactive compounds such as triterpenoids, phenolic acids, and flavonoids. This paper aimed to provide available information on the medicinal uses, phytochemicals, and pharmacology of species from Quercus. However, further investigation is needed to fully clarify the mode of action of its bioactive compounds and to evaluate in vivo chronic toxicity, before exploring their potential use as a supplement in functional foods and natural pharmaceutics.

“…In some Mediterranean countries, they are used in ice cream and other desserts or liqueurs. In Algeria, Morocco, and the eastern USA, acorn oil is produced (Makhlouf, Squeo, Barkat, Trani, & Caponio, 2018; Makhlouf et al., 2020), whereas in Northern Africa, they are consumed in such products as bread, cake, and coffee (Al‐Rousan, Ajo, Al‐Ismail, Shaker, & Osaili, 2013; García‐Gómez, Perez‐Badia, Pereira, & Puri, 2017; Pinna, 2013). Acorns are made up of compounds comparable to that of cereals and are a rich source of carbohydrates, mainly starch (31 to 51%).…”

Acorns, the fruit of the oak, have long been an important source of food in different cultures around the world. Despite their long culinary tradition, they have become under‐appreciated. Due to their high starch content, acorns are mainly used for flour production, and acorn flour is considered as a replacement for cereal flour in a wide range of applications in food production. This study reviewed the published literature concerning acorn flour production and composition as well as the possibility of using acorn flour in the most popular flour‐based products such as bread, cake, and cookies. The study also presents the advantages resulting from acorn flour incorporation to the human diet and acorn flour influence on the quality of bread and pastry products. This review found that acorn flour is characterized by a lack of gluten proteins and a high content of fiber and minerals as well as the presence of polyphenols with antioxidant properties. However, negative impact of its larger amount on the dough rheological features and product physical properties has been emphasized in many studies. The researchers recommend the incorporation of acorn flour up to a level of 15% in formulating composite flour for bread production. However, the literature data indicates that acorn flour substitution for pastry production depends on the product type and ranges from 10 to even 60%. It is also highlighted that the application of acorn flour into gluten‐free products is particularly favorable from a nutritional point of view.
