Brief Introduction

Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin. People use quercetin as a medicine.

Quercetin is used for treating conditions of the heart and blood vessels including “hardening of the arteries” (atherosclerosis), high cholesterol, heart disease, and circulation problems. It is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome (CFS), preventing cancer, and for treating chronic infections of the prostate. Quercetin is also used to increase endurance and improve athletic performance.

Main Function

1.Quercetin may expel phlegm and arrest coughing, it can also be used as anti-asthmatic.

2. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.

3.Quercetin may inhibit histamine release from basophils and mast cells.

4. Quercetin may control the spread of certain viruses within the body.

5, Quercetin may help reduce tissue destruction.

6.Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

QAAFI SCIENCE SEMINAR SERIES
28 March 2017

DESCRIPTION
The structure and material properties of growing and fleshy plant tissues are determined by their (primary) cell walls. The biological requirement in growing tissues for cell walls to combine structural strength with flexibility and extensibility is met through a network of cellulose fibres in a hydrogel form that is modified by the presence of other polysaccharides. From direct measurement on isolated plant cell walls and using a model bacterial cellulose hydrogel system, the molecular rules governing the association of non-cellulosic polysaccharides with cellulose fibres have been deduced. The effects of various features of cell wall hydrogels on the characteristic material properties under small deformation, compression and extension have been characterized and rationalized. Consequences for plant material properties and plant food behavior in the digestive tract will be discussed.

About Prof. Mike Gidley
Professor Mike Gidley is Director of the Centre for Nutrition and Food Sciences (CNAFS) in QAAFI. Prof. Gidley’s career includes 22 years in food R&D in the private sector and the last 13 years at UQ in the Centre for Nutrition and Food Sciences.

Research themes within CNAFS include ‘Smart Selections’ (how to identify the right combinations of raw materials and processing to deliver consumer-preferred foods), ‘Naturally Nutritious’ (maximising the intrinsic nutritional properties of agricultural products in foods and ingredients) and ‘Uniquely Australian’ (identifying and validating opportunities for elite products from foods and ingredients that can only have come from Australia).

Prof. Gidley’s own research is focused on structure – function relationships in important food components such as starch granules and plant cell walls. This has led to the detailed characterisation of starch and dietary fibre digestion/fermentation in vitro and in vivo, with the understanding generated leading to opportunities for optimising nutritional value of foods and feeds. He is a Program Leader in the Australian Research Council Centre of Excellence in Plant Cell Walls (2011-2017)

Many black spots or dark patches can be easily lightened or eliminated to restore a glowing facial complexion. Dark spots, patches and other marks on the face may be due to excess secretion of melanin on the skin.

Some factors that can lead to this condition include over exposure to the sun, hormone imbalance, pregnancy, certain medications, vitamin deficiencies, lack of sleep and too much stress.

Spots and patches on the face can be embarrassing and even lead to low self-esteem. Luckily, there are many possible treatments, such as acid peels and laser surgeries. Simple, natural homemade remedies also may reduce the appearance of spots and other blemishes on your face.

Here are top 10 home remedies for Black Spots on Face.
1. Lemon Juice
A quick and easy solution can be found in your kitchen or your nearest grocery store – lemon juice. Lemons have vitamin C that can lighten dark spots on your face. It’s easy to apply.

Put some fresh lemon juice on a cotton ball and rub it directly on the affected skin area.
Allow it to dry and then wash it off with plain water.
Continue applying this dark spot removal home remedy for at least two weeks to get the desired result.
If you have delicate or sensitive skin, you can dilute the lemon juice with plain water, rose water, or honey. You can also use lime juice to get rid of black spots, applying it in the same manner as described above.

2. Potato
Your vegetable drawer is another source of home remedies for black spots or dark patches. Potatoes have natural bleaching properties that help fade spots, scars as well as blemishes. The starch in potato helps reduce pigmentation, while the enzymes in it promote healthy skin.

Steps:
1.Peel and grate a potato.
2. Mix 1 teaspoon of honey in the grated potato.
3. Apply the mask on your face and allow it to dry for 15 minutes.
4. Rinse it off using lukewarm water.
Some people have also had success using tomatoes to get rid of dark black spots within a few weeks.

3. Aloe Vera
Aloe vera has many healing properties and is a great natural dark spot corrector. Its gel has polysaccharides that stimulate the growth of new skin cells to help reduce dark spots and heal scars.

A 2010 study published in the Journal of Chemical and Pharmaceutical Research throws light on many skin benefits of aloe vera gel. The study says that this gel can help clear dark spots and skin blemishes and make the skin clearer.

1. Extract fresh aloe vera gel from an aloe leaf.
2. Apply it directly on dark patches and black spots.
3. Gently massage the area with your fingertips for a few minutes.
4. Leave it on for 15 to 20 minutes, then rinse your face.
5. Repeat this once or twice daily for a few weeks to fade skin
discolorations.

4. Turmeric
Turmeric is another popular skin-lightening agent that can be used to get rid of black spots on your face. It repairs free radical damage and reduces skin pigmentation and discoloration. It is also effective for quickly removing sun spots and age spots.

1. Make a thick paste of 2 teaspoons of turmeric and a little milk
and lemon juice.
2. Apply it to the skin where there are black spots.
3. Leave it on for a few minutes and then wash it off with
lukewarm water.

Vitamin E oil and castor oil, too, are useful in getting rid of black spots.
