“…In this study, DPPH radical scavenging activity was analyzed for preliminary evaluation on the antioxidant activity of purified products. The radical scavenging activity of purified products was determined with slight modifications in the method [20]. A total of 2.0 mL from a 0.1 mM ethanol solution of the DPPH radical was mixed to 1.0 mL sample.…”

Morels famous for their taste and nutrition are in short supply all over the world although they were considered as one of the most highly prized edible and medicinal mushrooms. Because of the limitation of resource and cultivation technology, fermentation of edible mushroom was gradually applied to nutrient, bioactivity and breeder seed preparation. At present, there are more reports on sugar and amino acid but less on other components. Morchella sp. YDJ-ZY-1 was isolated from the wild fruiting body by the spores releasing method in Zunyi Guizhou province in Southwest China and identified based on phenotype and genotype characteristics. Chemical compositions of YDJ-ZY-1 were investigated from liquid fermentation that will lay the foundation for further development and utilization. Four pyranoids (1–4) and 2-(1-oxo-2-hydroxyethyl) furan (5), linoleic acid (6), Morelin (2-hydroxy-cinnamic acid methyl ester, (7) and 1-O-β-d-ribofuranose-Morelin (8) were obtained from EtOAc extraction and elucidated by spectral data. Product 4 and 8 were new compounds and 7 was isolated from nature for the first time. Antiradical activity was evaluated by free radical scavenging effect on DPPH (1,1-Diphenyl-2-picrylhydrazyl radical 2,2-Diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl). Compound 5 exhibited strong antiradical activity while compounds 1 and 2 exhibited moderate activity. Thus, incubation of Morchella sp YDJ-ZY-1 separated from the wild fruit body afforded eight compounds. Secondary metabolites with new structures were mined from fermentation of Morchella sp. and antiradical activity was evaluated.

“…TPC was not found to have a strong linear correlation with the antioxidant activity assessed using both methods. This is possibly due to antioxidant activity mostly attributed to phenolic-type compounds [41,42]. These compounds have been reported in fruit flesh and leaves of other species within the Annonaceae [41,43,44].…”

Annona montana Macfad is a fruit species of the Annonaceae family. In this study, the phytochemical potential of A. montana seeds was investigated. Ethanol and hexane extracts from seeds were evaluated for cytotoxicity and insecticidal activity, phenolic content, and antioxidant capacity. The latter being related to free radical scavenging activity assay (DPPH) and ferric reducing power (FRAP). Exposing Artemia salina to both seed extract types reveled their high toxicity with a median lethal concentration (LC50) of < 10 μg mL-1. Further A. montana seed insecticidal activity was evaluated against Thrips tabaci L., revealing that the most promising treatments were observed for a concentration of 100 mg L-1 in both extracts. The ethanol extract resulted in a mortality of 67.5 % and the hexane extract in a 53.3 % mortality. The ethanolic extract of A. montana seeds showed the highest total phenolic content: 297.38 mg GAE/100 g of dried extract and 192.66 mg TE/100 g, and 385.46 mg TE/100 g for DPPH and FRAP, respectively. The chemical characterization of both extracts by high performance liquid chromatography (HPLC) revealed the presence of acetogenins. The results obtained idicate that the A. montana extracts are a promising source of compounds with insecticidal activity.

“…Antioxidant compounds in the Spondias species are particularly relevant for the prevention and improvement of diseases related to oxidative stress. In the case of S. tuberosa , the presence of tannins and phenols in its peel has been reported [ 77 , 78 ], as well as organic acids in the peel, seeds, and pulp [ 78 ]. As well as this, total phenolic content in umbu was found to be high in the seed, peel, and pulp, consecutively.…”

“…Phenolic compounds were found in the pulps of cajá–umbu at a total concentration of 62.08 ± 0.069. According to the DPPH test, cajá–umbu showed higher antioxidant activity when compared to the commercial antioxidant butylhydroxytoluene [ 78 ]. Accordingly, other authors obtained a DPPH result of 10.53 ± 0.19 mmol Trolox/g sample and FRAP of 0.31 d 0.01 mmol Trolox eq/g sample.…”

Spondias sp: Shedding Light on Its Vast Pharmaceutical Potential

Many plants are used by the population through popular knowledge passed from generation to generation for the treatment of various diseases. However, there is not always any scientific content supporting these uses, which is very important for safety. One of these plants is the fruit of the Spondias genus, which during its processing generates various residues that are discarded, but which also have pharmacological properties. The focus of this review is to survey the pharmacological activities that Spondias genus shows, as well as which part of the plant is used, since there is a lot of richness in its by-products, such as leaf, bark, resin, seed, and peel, which are discarded and could be reused. The main activities of this genus are antioxidant, anti-inflammatory, antidiabetic, antifungal, and antiviral, among others. These properties indicate that this genus could be used in the treatment of several diseases, but there are still not many products available on the market that use this genus as an active ingredient.
