“…It is also known as the Genus fragaria. Flavonols, a class of phytochemicals that also includes ellagitannin, chlorogenic acid, salicylic acid, and caffeine acid, have several positive health effects, including the regulation of heart function, gastric cancer 64 . When strawberry (Fragaria ananassa) leaves were extracted and tested for effects on DN in rats, it was discovered that both insulin and blood glucose levels increased 65 .…”

The purpose of this study was to collect data for future clinical investigations and research on the safe and efficient use of various herbal medicines to treat hyperglycemia. One of the primary contributing reasons to the onset and progression of diabetic nephropathy is hyperglycemia, and many modern treatments are made from plants since they frequently have fewer side effects than the conventional medications that are now available. The medicinal plants include Sesbania sesban, Elaeis guineensis, Tecoma stans, Aloe barbadensis miller, Zingiber officinale Roscoe, Olea europaea, Anogeissus acuminata, Juglans regia L., Fragaria ananassa, Ginkgo biloba, Laurus nobilis L., Dryopteris dilatata, Moringa oleifera, Punica granatum L., Lycium chinense, Rumex nervous alkaloids and flavonoids are the primary phytoconstituents that aid in the therapy or cure of diabetic nephropathy. The therapeutic effects of medicinal plant leaf extract may be due to the wide range of bioactive compounds present, including various phytoconstituents such as alkaloids and flavonoids, glycosides, steroids, terpenoids, and phenolics. Alkaloids and flavonoids are the primary phytoconstituents that aid in the therapy or cure of diabetic nephropathy.

“…The anti-inflammatory and antioxidant function of strawberries means they can ward off UV radiation. Flavonoids, tannins, phenols (ellagic acid) are related to inhibiting the inhibitory activity of the tyrosinase enzyme and binding to cooper which is related to the formation of melanin (Rapuru et al, 2023).…”

Skin aging occurs due to prolonged exposure to ultraviolet B (UVB) resulting in oxidative stress, which stimulates an increase in tyrosinase enzyme and melanin, causing hyperpigmentation. Chemical-based sunscreens often cause allergy and irritation, while hydroquinone (HQ) causes negative effects on the skin called ochronosis. Natural ingredients that are safe from side effects, such as strawberry (Fragaria ananassa), with active compounds of flavonoids, tannins and phenols with antioxidant and antiinflammation activity, can reduce melanogenesis. The aim of this study was to determine the effectiveness of 12,5% strawberry ethanol extract cream before and after UVB exposure in reducing levels of the tyrosinase enzyme and the amount of melanin in male guinea pigs. The research was a randomized post-test only control group design experimental study, using 30 male local strains guinea pigs, aged 3-4 months, weighing 300-350 grams, divided into three groups, consisted of 10 guinea pigs each. The control group (K0) was given UVB exposure and basic cream, treatment group 1 (K1) was given 12,5% strawberry extract cream before UVB exposure and treatment group 2 (K2) was given 12,5% strawberry extract cream after UVB exposure for 2 weeks. Skin samples were taken by biopsy and examined for tyrosinase enzyme levels using the ELISA method and melanin amount using the histopathological method of Masson-Fontana staining. The data was analyzed using One Way ANOVA and Post Hoc Tamhane. The mean levels of the tyrosinase enzyme in treatment group K1 and K2 (8,25 1,5 ng/ml and 17,47 3,09 ng/ml; p<0,05) decreased significantly compared to K0 (34,57 5,62 ng/ml). The mean amount of melanin in treatment group K1 and K2 (3,8 3,9%pixels and 5,13 1,53%pixels; p<0,05) decreased compared to K0 (21,16 10,21%pixels). There was significant difference in the decrease of tyrosinase enzyme in treatment group K1 and K2 (p<0,05), while no significant result was found in the decrease of melanin in treatment group K1 and K2 (p>0,05). In conclusion, 12.5% strawberry ethanol extract cream reduced tyrosinase enzyme level and melanin amount compared to control group applied with base cream, with better result when applied before UVB exposure (protection effect) than after UVB exposure (for treatment), with the same effectiveness in reducing the melanin amount but different effectiveness in reducing the tyrosinase enzyme.

“…Strawberries ( Fragaria × ananassa Duch.) have become an increasingly popular fruit due to their colour, texture and taste, leading to a rising demand in the market (Rapuru et al ., 2022); beyond their delicious flavour, strawberries are associated with several health benefits. These include reducing and even preventing heart disease due to their antioxidants and polyphenols, which protect heart health and prevent various types of cancer (Davis et al ., 2007).…”

SummaryStrawberry (Fragaria x ananassa Duch.) belongs to the Rosaceae family. The fruit is very beneficial, with a delicious taste, attractive colour, and high vitamin and mineral content. The effect of chitosan on juice's transparency and phytochemical properties from the Camarosa cultivar was evaluated. Using chitosan as a clarifying agent for strawberry juice significantly reduced turbidity, phenolic content, flavonoids, protein, and antioxidant properties. In contrast, the quantity of soluble solids, titratable acidity, pH, folate, Vitamin C, anthocyanin, and carbohydrates showed no significant changes. Changes were also observed in the colour‐related parameters of the juice. In order to assess potential contamination in strawberry fruit, the levels of heavy metals and pesticide residues were analysed separately using ICP and GC‐MS techniques. There was a significant reduction in the levels of Cu, As, Co, Pb, and Cd in strawberry juice after treatment with chitosan. Reducing heavy metals in fruit juice using chitosan helps improve the fruit juice's safety, nutritional properties, and health benefits. It can be posited that chitosan affords the production of a more nutritious and healthier fruit juice as compared to natural strawberry fruit. Using chitosan as a clarifying agent produces a juice with extraordinary clarity, improves the safety, health benefits, and nutritional value, and produces a consumer‐friendly product.
