“…According to the used standards in the present study, we presumed that catechin and epicatechin were (+)‐catechin and (−)‐epicatechin, respectively. Compared with the seeds from natural population, quercetin, p ‐coumaric acid, and dihydroquercetin were not found in the seeds of cultivated populations. These results indicated that the seeds from natural population contained a higher variety of phenolic compounds than that of cultivated populations.…”

The purpose of this study was to analyze the phenolic profiles of seeds from fifteen Paeonia ostii cultivated populations in China and identify their relationship with antioxidant activities and associated environmental factors. Thirteen individual phenolic compounds were quantitatively determined by HPLC, and (+)-catechin was the most abundant phenolic compound in the seeds. Correlation analysis showed that phenolics were the most effective antioxidant compound class by evaluating DPPH, ABTS, and hydroxyl radical scavenging activities as well as ferric reducing antioxidant power. Latitude and annual rainfall had significant effects on the contents of many phenolic compounds, and elevation was only significantly correlated with gallic acid content. Within fifteen P. ostii cultivated populations, the seeds of Tongling population exhibited the highest phenolic contents and strongest antioxidant activities. These results suggest that Tongling population has a relatively high utilization value and a potential for sources of natural antioxidants.

“…The flavonoids content was measured by the aluminum chloride colorimetry as proposed by X. Zhang, Shi, Ji, Niu, and Zhang (2017) with some modification. Briefly, 3 ml of methanol and 1 ml of 5% (wt/vol) sodium nitrite were blended with 5 ml of C. militaris extract.…”

Radio frequency (RF) was applied to heat Cordyceps militaris for the purpose of quality evaluation and microorganism control. RF heating caused gradual temperature increases ranging from 59.6 to 63.8°C, resulting in good heating uniformity and uniform temperature distribution. Compared with conventional high pressure steam (HPS), RF heating resulted in significant (p < .05) higher total phenolic, flavonoids, and cordycepin contents of C. militaris. In addition to higher reduction of total aerobic bacteria counts, bitterness taste value increased from 2.35 (unpasteurized) to 4.79 (HPS). Umami value significantly decreased from 13.58 (unpasteurized sample) to 12.13 (HPS treated sample). Nuclear magnetic resonance analysis showed that 20 min of RF significantly reduced the loss of water mobility than HPS. Principal component analysis of taste characteristics indicated distinct differences between RF and HPS treated samples. Hierarchical clustering analysis also revealed higher similarity between RF heated samples and the unpasteurized one. Practical applications Cordyceps militaris is an edible and medicinal mushroom with high nutritional quality. Results of the present study indicate that radio frequency (RF) contributed to higher umami taste, higher retention of bioactive compounds, and higher water mobility of C. militaris. Therefore, this process can be used to develop a promising alternative to conventional thermal method for the processing of C. militaris. It is highly possible that RF could be applied to healthy food industries.

Plants, through the photosynthesis process, produce the substances necessary for all the life cycles of nature, which are called "primary metabolites." Moreover, there are some plants that synthesize, in addition to these, other substances with more specific functions, which are known as "secondary metabolites." It is inside this group that flavonoids are located, whose main function is to protect organisms from damage caused by different oxidizing agents. Luteolin (3,4,5,7-tetrahydroxy-flavone) belongs to the sub-class of flavonoids known as flavones and is one of 10,000 flavonoids currently known,
