The antioxidant activity of tea seed oil (camellia oleifera) and its active components were investigated. Extraction was performed with five different solvents and it was observed that the methanol extract had the strongest antioxidant activity. Sesamin and a new compound (compound B) were identified. The results indicate that both of the components significantly isolated show antioxidant activity (sesamine is one of the two main components in sesame oil lignans) and they have health-enhancing effects with antioxidant effects. In addition to the traditional pharmacological effects of tea seed oil, it is safe to say that tea seed oil has a role as a prophylactic agent in diseases related to free radicals.

Pharmaceuticals are means for changing and protecting the skin from abnormal or pathological conditions. Cosmeceuticals are not drugs, they includes active ingredients which not disturb the normal skin conditions. Panthenol physically increases the barrier properties of the stratum corneum. The natural protective mechanism of the skin has two types: enzymatic and non-enzymatic (antioxidants).

Zinc concentration was measured in 308 normal newborns and 199 infants of 1-12 months of age by means of atomic absorption spectrophotometry. The zinc concentration in hair was 204 mcg/g at birth but decreased to 112 mcg/g at 8 months and increased to 144 mcg/g at 12 months. Rash in the diaper region is particularly associated with a decrease in the level of zinc in the hair, and the level of zinc in those with less hair is less than that of those with a lot of hair. The data indicate that hair loss and diaper region rash in normal newborns are associated with a decrease in zinc levels, especially in the hair.

Moisturizers are used by many people on a daily basis to reduce the symptoms of dry skin. Topically applied lipids are said to be structurally and functionally effective on the permeability barrier. The effects of 9 different oils in the normal skin and SLS-irritated skin were investigated in 21 healthy individuals. Apparent irritation, blood flow in the skin and TEWL were measured. The tested substances are non-soap substance fractions obtained from hydrocortisone, petroleum jelly, fish oil, borage oil, sunflower oil, canola oil, karite oil, canola, and karite oil. Water was added as the control group. No significant differences were observed between test substances in normal skin. However, differences were observed between SLS-irritated skins. With the use of sterol-enriched canola oil following water, the signs appearing on the SLS-irritated skin are less commonly mentioned. This fraction and hydrocortisone reduced blood flow in the skin. Additionally, hydrocortisone, canola oil and its sterolce enriched fraction significantly reduced TEWL compared to water. Other lipids had no significant effects on irritation. As a result, lipids commonly used in moisturizers reduce skin reactions against irritants. Previous studies have shown that sterol synthesis is increased in damaged skin. Canola oil and its fractions have been shown to support the skin barrier damaged by appropriate lipids in the SLS-irritated skin.

The shells derived as by-products while C.oleifera oil was obtained have not been evaluated. The aim of this study is to evaluate the anti-inflammatory and analgesic effects of flavanoids obtained from these shells. Camphenol flavanoid was defined and this substance was first found in C.oleifera. It showed an anti-inflammatory effect depending on the dose. Additionally, bioflavonoids showed an analgesic effect, unlike aspirin. Bioflavonoid significantly decreases malonaldehyde (MDD) and increases the activity of superoxide dismutase and glutathione peroxidase in serum, and acts against free radicals in in vivo studies.

In this study, we will focus on macronutrients, micronutrients in the pulp, extract, and oil of karite oil, and the physicochemical properties of karite oil. The extract of the plant is high in oil and the oil obtained by extraction using traditional method is used in food preparation, medical and cosmetic industry. Biochemical properties of the karite oil show some antioxidant and anti-inflammatory effects.

Efficacy and safety of some of the ingredients used in innovative cosmeceuticals

The effects of some substances frequently used in innovative cosmetics on the skin are evaluated below;

Dexpanthenol

Pantothenic acid (vitamin B5) is a component of Coenzyme A and acts as a cofactor in many enzymes catalyzing reactions. These reactions are the metabolization of carbohydrates, fatty acids, proteins, sterols, steroid hormones, and profilin. Panthenol is the alcoholic analog of Vitamin B5.

Similar names are listed below;

Dexpanthenol:D-panthenol: Panthotenik asit: Vitamin B5

Topical use of Dexpanthenol (the stable alcoholic analog form of pantothenic acid) increases the hydration of the stratum corneum, decreases transepidermal water loss (TEWL) and provides the softness and elasticity of the skin, moisturizes and soothes the skin.

Aloe Vera

Aloe vera softens the skin.

Chamomilla Recutita

Beta the bisabolol obtained from Chamomile has an anti-inflammatory and antibacterial effect.

LS-ES1-IT-TOF/MS and LC/UV-ELSD methods were used for qualitative analysis of triterpene saponins from tea seed pulp (Camellia oleifera abel). LC/UV method was also developed for the quantitative analysis of oleifera saponin A1. Purified total saponins exhibited no inhibitory effect at concentrations of 0.1-10 mg/ml except for S. aureus and E. coli. They showed high inhibitory activity against fungi, especially against bipolaris maydis.
