The medicinal and edible plant, Ficus hirta Vahl. (also called hairy fig), is used for the treatment of constipation, inflammation, postpartum hypogalactia, tumors, and cancer. There is an urgent need for scientific evaluation to verify the pharmacological properties of F. hirta. Therefore, in vitro assays evaluated the antioxidant and antifungal activities of various solvent extracts of hairy fig fruits (HFF). HFF extracts had abundant antioxidant components for a significant amount of total phenolic (TPC) and flavonoid contents (TFC) (TPC from 17.75 ± 0.52 to 85.25 ± 1.72 mg gallic acid/g dw and TFC from 15.80 ± 0.59 to 144.22 ± 8.46 mg rutin/g dw, respectively). The ethyl acetate extract (EAE) and acetone extract (AE) of HFF demonstrated potent antioxidant activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH) (IC50 values of 2.52 and 2.02 mg/mL, respectively) and ABTS radicals (IC50 values of 3.06 and 9.26 mg/mL, respectively). Moreover, the AE with a high TFC showed a prominent in vitro and in vivo antifungal activity against Penicillium italicum, causing citrus blue mold. Eighteen metabolites were identified or putatively identified from six HFF extracts. Current findings indicated that HFF extracts had significant antioxidant and antifungal activities and could potentially be used as an alternative agent for the preservation of agricultural products.

“…There are hardly any scientific studies about the antioxidant and antifungal activities of hairy fig fruits (HFF). The HFF is a famous herbal medicine known in China by the name of 'Wú Zhǐ Máo Táo Guǒ', and has been used in both medicine and food for centuries by Hakka people [1,7,8].…”

“…Citrus fruits (Family Rutaceae, subfamily Aurantioideae) are highly susceptible to decay caused by more than 20 postharvest fungal infections leading, to approximately half the crop wasted due to fungal diseases [2]. Among various fungal strains, Penicillium fungi cause serious plant diseases and damage to the citrus crop during storage, accounting for about 10-30% [3]. The P. digitatum infects the citrus fruits, causes green mold disease, and generates huge (60-80%) yield losses under ambient conditions [4].…”

Carvacrol (5-Isopropyl-2-methylphenol), a volatile oil constituent, mainly exists in Labiaceae family plants. Carvacrol has long been studied for its natural antifungal potential and food preservative potential. However, its exact mode of action, especially against Penicillium digitatum (P. digitatum), remains unexplored. Herein, a 1 H-NMR-based metabolomic technique was used to investigate the antifungal mechanism of carvacrol against P. digitatum. The metabolomic profiling data showed that alanine, aspartate, glutamate, and glutathione metabolism were imbalanced in the fungal hyphae. A strong positive correlation was seen between aspartate, glutamate, alanine, and glutamine, with a negative correlation among glutathione and lactate. These metabolic changes revealed that carvacrol-induced oxidative stress had disturbed the energy production and amino acid metabolism of P. digitatum. The current study will improve the understanding of the metabolic changes posed by plant-based fungicides in order to control citrus fruit green mold caused by P. digitatum. Moreover, the study will provide a certain experimental and theoretical basis for the development of novel citrus fruit preservatives.aroused by excessive use of certain routine and synthetic antifungal agents. Over the past few decades, the intentions have been to ensure the hygiene and safety levels of fruit products along with promoting maximum biodegradability. In order to achieve this ambition, researchers are still trying to screen natural products with strong antifungal potential from plants. Moreover, it has also been tried to explore new preservation technologies that can replace synthetic fungicides. Compared with synthetic fungicides, natural antifungal substances have attained much attention in recent years [6][7][8][9].Various essential oils refined from Melaleuca alternifolia have strong inhibitory effects on multiple fungal strains, particularly P. italicum Wehmer and P. digitatum Sacc., and hence can be used as natural preservatives in agricultural and food processing [10]. Previously we have reported that cinnamaldehyde contained in cinnamon has a good antifungal effect against P. italicum and clarifies the method for dynamic detection of the antifungal effect of cinnamaldehyde [11]. In addition, GC-MS and GC-FID techniques successfully separated the essential oils components viz. limonene (87.02%), linalyl acetate (53.76%) and linalool (39.74%) from peels, leaves and flowers of Citrus aurantium var amara, neroli oil appeared as the best fungistatic agent, which reduced the P. digitatum sporulation to 25 % at a 50 mg/mL concentration of oil [12].Carvacrol (5-Isopropyl-2-methylphenol) is the major volatile oil constituent from Labiaceae family plants, such as oregano, mint, and thyme [13]. Carvacrol has many medicinal and edible applications, including antifungal, antimicrobial, anti-inflammatory, insecticidal, antitumor, and other effects [14]. Carvacrol inhibited the growth of P. digitatum and P. italicum in in vitro and in vivo experiments of l...

There are numerous publications on preservation using chitosan (Benhabiles et al, ; Chen, Cai, Chen, Peng, & Wan, ; Gao, Kan, Chen, et al, ; Gao, Kan, Wan, et al, ; Migliori, Salvati, Cesare, Lo Scalzo, & Parisi, ); however, there are only a few studies on preservation using CMC. Therefore, we decided to study the preservation properties of CMC.…”

Polysaccharides from Osmunda japonica Thunb (Op) exhibit a wide range of biological activities including antibacterial, anti‐inflammatory, antioxidant, and antitumor effects. Carboxymethyl cellulose (CMC) is a type of cellulose derivative that can form dense films. CMC can slow the respiratory transpiration of tomatoes and reduce water evaporation. Coatings of CMC (0.7% concentration) with various levels of Op (0.02%, 0.04%, 0.06%, 0.08%, and 0.1%) were used to preserve tomatoes at room temperature. The treatment, weight loss, hardness, titratable acidity (TA), respiratory intensity, and concentrations of ascorbic acid, polyphenol oxidase, and malondialdehyde (MDA) were evaluated in tomatoes after 0, 5, 10, 15, 20, and 25 days of storage. Compared with untreated tomatoes, the tomatoes with Op‐incorporated CMC coatings had reduced respiratory intensity, weight loss and ascorbic acid loss, increased TA, controlled MDA, and inhibited the decay of tomatoes. Therefore, the use of Op‐incorporated CMC coatings extended the shelf life and maintained the quality of postharvest tomatoes. Practical applications In the past decades, the use of edible coatings has attracted widespread interest in extending the shelf life of particularly perishable foods. Currently, applications of edible coatings have been proven to be promising as a tool to improve the quality and extend the shelf life of various fruits. But there have been no reports on the effect of Op‐incorporated CMC treatment on the postharvest quality of tomatoes during storage. The purpose of this work is to investigate the efficiency of Op‐incorporated CMC treatment to extend shelf life and provide theoretical guidance for the preservation of tomatoes.
