“…For example, darker color was shown to be associated with increased antioxidant activities and polyphenol contents in honey samples (46). Moreover, the higher antioxidant activity in highly colored malts was shown to be related to higher contents of reductones and melanoidins, which are produced during the roasting process (47).…”

The major trend in the antioxidant market is the growing consumer demand for natural antioxidants. Tea, one of the most widely consumed beverages in the world, is an easy way to obtain antioxidant components from a natural source. Our objective was to develop burdock root tea (BRT) with potent antioxidant activity and good color quality. In order to obtain maximum antioxidant activity and quality, the effect of roasting was determined. The antioxidant capacities and total phenolic contents of BRT increased as roasting increased. The color of BRT became darker with increased roasting, extraction time, and amount of burdock roots. Color of BRT was also positively correlated with total antioxidant capacity. Roasting significantly enhanced the total antioxidant activities and color quality of BRT. These results suggest that roasting BRT increases beneficial antioxidant components from burdock roots.

The use of plants to improve dental health and to promote oral hygiene has been practiced for centuries and persists in several communities throughout the world. Salvadora persica (Miswak) has a wide geographic distribution. The ancient Arabs had the habit of using it to whiten and polish the teeth. Here, we determined in vitro antioxidant activity, total phenols and flavonoids and evaluated antiproliferative activity of the extract of S. persica (Miswak). The MTT assay was used to estimate the antiproliferative activities of the extract against human hepatoma (HepG2) cancer cell line. Inhibition percentage of DPPH scavenging activity was dose-dependent and ranged from (30.7% ± 0.62) to (5.89% ± 0.98). The phenolic content was (2.7 ± 0.11) mg GAE/g while the flavonoid content was (2.70 ± 0.45) mg QE/g. Antiproliferative results of the extracts were found to be consistent with their antioxidant activity. Our extract also exhibited clear antiangiogenic activity. These findings introduce S. persica as the useful and novel potential anti-tumor agent for hepatocellular carcinoma (HCC) treatment.

“…Aforesaid reviews indicated that free radicals and nitric oxide signaling play critical roles in the growth of opioid analgesic tolerance and dependence, and radical scavenging agents, as well as nitric oxide synthase inhibitors, can be possibly implemented within the avoidance of morphine tolerance and withdrawal syndrome 5,21,22,2,4 . The excessive antioxidant activity of honey and its compounds have been discovered in common reports 23,24,26,27,28 . Moreover, a bioactive component of honey along with a phenolic compound, adequately overthrows gathering of reactive oxygen and nitrogen species and re-establishes endogenous antioxidant glutathione degrees and up-regulates the countenance of antioxidant enzymes.…”

Introduction:Honey has been used traditionally in medicine as well as food supplements. Honeybees are said to be able to cure many diseases. However, its influences on opioid tolerance and dependence have not yet been clarified.Materials and Methods:Adult male SpragueDawley rats were rendered tolerant to the analgesic effect of morphine by injection of morphine (10 mg/kg, i.p.) twice daily for 14 days. To develop morphine dependence rats given escalating doses of chronic morphine. To determine the effect of stingless bee honey on the development of morphine tolerance and dependence. The hotplate and naloxone precipitation tests were used to assess the degree of tolerance and dependence, respectively.The results: Our results showed that chronic morphine-injected rats displayed tolerance to the analgesic effect of morphine as well as morphine dependence. Methadone+morphine (MetM), methadone+morphine+ honey (MetMH) and morphine+Honey (MH) significantlylower the development of morphine tolerance with p-value p<0.05. In addition, concomitant treatment of morphine with MH and MetMH attenuated almost all of the naloxone-induced withdrawal signs which include abdominal contraction, diarrhea, pertussis, teeth chattering, and jumping. Conclusion: The data indicate that honey has a potential to reduce tolerant and dependence property.
