Introduction: After bleaching treatment, patients often require additional intervention for composite resin restorations. The initial composite restorations after bleaching with hydrogen peroxide (H₂O₂) 25-40% cannot be done immediately, due to the presence of free radical residues as a result of oxidation of the bleaching material it is recommended to delay bonding for 1-3 weeks. If the adhesive restoration are carried out immediately, the shear bond strength of the restoration would reduced. Free radicals can interfere with resin infiltration and inhibit complete polymerization. The use of antioxidants as an effective alternative treatment to overcome free radical residues and increase the shear strength of post-bleaching restorations. Alpha tocopherol is an antioxidant that has been known to bind free radicals, that adhesive action can be carried out immediately after bleaching. The potential natural resource being developed is moringa leaves (moringa oleifera lam) which is rich in antioxidants. The purpose of this study was to compare the differences in the use of antioxidants 10% alpha tocopherol and 10% ethanol extract of moringaleavescanincreasetheshearbond strengthoftheattachment in nanofilledcompositerestorationsonteethafterbleachingwith 40% H₂O₂

Our results show that the pesticides butylcaptax, dropp and karate are highly toxic pesticides, when exposed to these pesticides, the activity of the enzyme of the P-450 monooxygenase system is disrupted. Also, the research results showed that when poisoning with the above pesticides, ultrastructural, and therefore functional changes in the subcellular components of embryonic hepatocytes occur. When using RAF (plant antioxidant factor), enzyme activity and other indicators are significantly restored, which indicates that RAF has antioxidant properties.

Medicinal plants and plant derived products have been part of the health care system since ancient human civilization. Traditional medicine uses plant extracts because of it’s antioxidant activity. In contrast usage of synthetic antioxidants are being restricted due to several limitations. Thus, there is always demand for newer and alternative phytomedicines. The aim of the present study is to analyse phytochemical components and to explore the In vitro antioxidant potential of methanolic extract of Enicostemma hyssopifolium (MEEh). The plant extract was prepared by organic solvents. The MEEh was used for GC/MS analysis and for exploring the prospects of Enicostemma hyssopifolium. The radical scavenging bioassays such as DPPH and ABTS were carried out to study in vitro antioxidant potency. The lipid peroxidation assay was performed to analyse their inhibitory effects and ferric reducing power of the extract was also evaluated. GC/MS analysis revealed that the plant is a rich source of phytochemicals such as 3,5-Dimethoxyacetophenone, Ergost-5-en-3-ol which are known to have antioxidant potency. In the antioxidant assay of MEEh the IC 50 was found to be 655.3>306.6 μg/ml. In lipid peroxidation assay, 33.45% of inhibition was found at 1000 μg/ml. The findings of the study revealed the potential of Enicostemma hyssopifolium as a source for natural antioxidants. It revealed that the plant could be a promising alternative agent in scavenging free radicals and may have ameliorative effect in complications associated with free radical damage.

Plants, acting as an essential source of nutrients and medicinal ingredients, have long
been known for their natural arsenal. Human beings have used plants as medicinal items for
around 600,000 years. The preparations released from certain plants lead to plant medicines.
Today, plant medicines are popular worldwide, where herbs are used as primary medicines
by around 80% of the world’s population. This medicinal importance is primarily due to the
richness of bioactive phytochemicals in plants.
In this study, we aimed at screening the phytochemicals and biological activities of
Tarlmouniaelliptica(DC.) Fresh leaves, derived from plant material, were dissolved in four
different solvents methanol, chloroform, benzene and distilled water. The phytochemical
composition of extracts showed the presence of alkaloids, phenolics flavonoids and
terpenoids. DPPH radical scavenging and Fe2+ chelating activity assays and
Phosphomolybdenum assay were used to assess the antioxidant potential. The antiinflammatory
potential was evaluated by analyzing the Inhibition of albumin denaturation.
Biological activity of extract such as anti-diabetic and anti-fungal activity was also tested and
the result showed maximum activity of plant species.
Collectively, our observations suggest a promising potential for
Tarlmouniaelliptica(DC.) during the treatment of diseases associated with oxidative stress,
aberrant inflammatory responses, and glucose-sugar control. However, further experimental
procedures are needed to support this postulate.

Gout is characterized as an inflammation and warmth in the joints. It is associated with hyperuricemia wherein an upregulation of xanthine oxidase in purine degradation leads to increased levels of uric acid in the blood. Gout is not fatal. However, it affects one’s quality of life. Thus, this research primarily focuses in determining the inhibitory activity of xanthine oxidase in the methanolic leaf extract of bitaog (Calophyllumblancoi), bolongeta (Diospyros pilosanthera), and duhat (Syzygiumcumini) in gout. A quantitative-experimental research method was used in the study and the data were obtained by measuring the percent inhibition of the samples using UV-Vis spectrophotometer at 290 nm. The results showed that the methanolic leaf extract of above stated plants exhibited exemplary inhibition in comparison with the standard drug, allopurinol. The IC50 value determines the ability of the inhibitor to decrease the biotransformation of a substrate. The principle behind IC50 is, the lower the value the higher the inhibition. The bitaog (Calophyllumblancoi) trials have the lowest IC50 value with an average of 124.3 after the standard drug, followed by bolongeta (Diospyros pilosanthera) have an average of 155.3 IC50 value. Then duhat (Syzygiumcumini) showed the highest IC50 an average of 208.8.The bitaog (Calophyllumblancoi), next to allopurinol, showed the highest inhibition among all the extracts followed by the bolongeta (Diospyros pilosanthera). The least inhibitory activity was observed in duhat (Syzygiumcumini). Hence, it can be concluded that bitaog (Calophyllumblancoi), bolongeta (Diospyros pilosanthera), and duhat (Syzygiumcumini) can inhibit xanthine oxidase using in vitro analysis
