“…Finally, the fruits of C. pinnatifida were subjected to in vitro digestion and it was determined that 37.41 and 31.51 mg GAE/g DW of TPC were released for Shanlihong and Dajinxing, respectively, while procyanidin B2, epicatechin, chlorogenic acid and catechin were the major released flavonoids. ORAC and peroxyl radical scavenging capacity well correlated with the released TPC or flavonoids (Zheng et al, 2018).…”

Hawthorn (Crataegus spp.) is one of the most famous plants which has been used as natural medicine and nutraceutical. Its phytochemical composition, bioactive compounds and health benefits have been intensively studied and hawthorn preparations may be recognized as classical natural products for cardiovascular health. Polyphenolic compounds of different hawthorn anatomical parts as well as their extracts have been the focus of a majority of these studies, although various other classes of natural health promoting constituents have also been isolated, identified and characterized. Regardless, numerous published reports have particularly focused on the activity mechanisms which are very important for supporting various health benefits. This review summarizes the most recent studies on hawthorn, mainly published since 2015. Search of different databases indicates that approximately 200 publications, which are relevant to phytochemistry and health benefits of Crataegus spp., have appeared since then, most of them have not been included in the existing reviews.

“…The mixture was then left to stand for 2 hr. Absorbance was then measured at a wavelength of 765 nm, and a standard curve linear regression equation was used to calculate the total polyphenol concentration and yield (Zheng et al, ). The extraction yield was calculated using the following formulation.

% Extraction yield = \frac{C \times V \times Dilution times}{1.00 \times 1, 000} \times 100 .

The objective of this research was twofold: first, to optimize the extraction process of Lonicera japonica polyphenols using a response surface methodology, and second, to study the antioxidant activity and tyrosinase inhibitory capacity of the polyphenols of different purities. High‐speed shearing homogenization extraction was used to extract the polyphenols from L. japonica . The antioxidant activity and the effect of polyphenols on tyrosinase activity were studied using free radical scavenging assay and the tyrosinase method, respectively. The optimal extraction conditions with an extraction yield of 6.96% for polyphenols were determined as follows: ethanol volume fraction 57%, shearing time 3.30 min, and solid–liquid ratio 1:58. Lonicera japonica polyphenols exhibited potent scavenging activity on 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) and 2, 2'‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS), and inhibitory capacity on tyrosinase. The results suggested that L. japonica polyphenols could be explored as a natural antioxidant and tyrosinase inhibitor.

“…Free phenols in the shell pigment decreased during gastro-intestinal digestion. According to a previous study on the simulated digestion of hawthorn, some new unknown peaks were detected by high-performance liquid chromatography (HPLC) after digestion, evidencing the existence of new compounds [34]. Hence, the decreased free phenols in shell pigment maybe converted or degraded into other chemical compounds.…”

“…A previous report [7] revealed the existence of ellagic acids in walnut husk, and this may also explain the α-amylase inhibitory effect in husk pigment. Since the amount and position of hydroxyl groups in flavonoids regulate their α-amylase inhibitory ability [34], flavonoids in husk pigment may undergo structural changes during digestion. In the light of a previous study [44], the inhibition toward the α-glucosidase activity of raspberry dried seeds was improved in simulated small intestinal digestion, suggesting that the digestive progress is beneficial for phenolic compounds to play a hypoglycemic function.…”

To assess the effects of digestion on the functional components of walnut pigment and their bioactivities, we developed an in vitro model simulating gastro-intestinal digestion. Results showed an increase in the contents of flavonoids and conjugated phenols (with retention rates higher than 100%) in husk pigment after digestion. The lowest of the 2,2 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging abilities was reached in the group with the minimum flavonoid content after digestion. Close correlation was observed between free phenol content and total reducing power, as the reducing power among different groups of husk pigment was in consistent with free phenols changes. The inhibitory effect of walnut pigment on α-amylase with/without digestion enzyme was similar. However, shell pigment showed improved inhibitory effect on α-glucosidase activity, with an increased inhibitory rate of 5.42%. In general, the antioxidant activity and hypoglycemic ability of walnut pigment were prone to chemical and enzymatic changes during simulated digestion, which were also related to the alteration of flavonoids and phenols.
