Mangosteen: Xanthones (3/5)

Medical Properties of Xanthones

Research on Xanthones is ongoing. There are many results people report about health benefits from xanthones that cannot be explained by the science yet. This is likely due to the fact that only about 15% of known xanthones have been studied to any degree.

Some of the known benefits of xanthones based on recent research are:
- Anti-Fatigue - Helps boost energy.
- Anti-Inflammatory - Helps prevent and reduce inflammation
- Anti-Aging
- Helps prevent cancer. According to a preliminary study, six xanthones have been found to be capable of killing cancer cells.
- Helps lower blood pressure
- Helps lower blood sugar. Many people with type II diabetes have reported that it helps them to regulate their blood sugar levels.
- Helps prevent infections - Bacteria, Microbes, Viruses, Fungus.
- Anti-Diarrheal - In folk medicine, the pericarp of the mangosteen (most potent source of xanthones) has been used for centuries to effectively treat dysentery.
- Anti-Parkinson, Anti-Alzheimer. Helps prevent dementia.
- Anti-allergenic - Helps with allergies
- Eye Care - Helps prevents cataracts and glaucoma
- Helps protect the heart and cardiovascular system
- Anti-Obesity

A recent study has confirmed that gamma mangostin, a xanthones derivative found in the mangosteen, is a potent COX (Cyclooxgenase) 2 inhibitor. The COX 2 enzyme is a chemical in the body that causes inflammation. This enzyme is commonly found in people suffering from joint pain and arthritis. However, it is also being found with other diseases as well, that are not as obvious, such as Parkinson's, Alzheimer's, cancer, and Diabetes. In three separate studies, a xanthones derivative of the mangosteen slowed down the body's production of the COX 2 enzyme.

Mangosteen: Drink Recipes

Mangosteen Lassi (nonalcoholic)
Cool and refreshing, this take on the traditional mango lassi pairs well with spicy foods.

1/2 cup cold Adam's 100% Mangosteen Nectar
1/3 cup plain yogurt
2 tablespoons milk
1 teaspoon honey
Dash of cardamom (optional)

Combine the Adam's 100% Mangosteen Nectar, yogurt, milk, and honey in a blender. Blend well on high speed until very frothy, 1–2 minutes. Pour into a tall glass and sprinkle with the cardamom, if desired. The lassi can be stored in the refrigerator for up to three days, but it’s best served blended again until frothy before serving.



Punchless Mangosteen Punch (nonalcoholic)
If you prefer, you can make this drink without a blender. Simply shake all the ingredients in a cocktail shaker with ice and strain into an old-fashioned glass filled with ice.

3 ounces Adam's 100% Mangosteen Nectar
1 ounce pear nectar
1/2 ounce lime juice
1/2 ounce simple syrup
1/2 cup ice
1 pear slice (optional)

Combine all the ingredients in a blender and blend until smooth. Pour into an old-fashioned glass, garnish with a pear slice, and serve with a straw.

Durian: King of Fruits









Scientific Name : Durio sp.
Indonesian Name : Durian
Other Common Name : Durián (Spanish), Durion (French), Doerian (Dutch)

Origin
Native to Indonesia, Malaysia, and Brunei.

Uses
Normally eaten fresh, dodol, ice cream, fermented.

Nutrient Content
Durian fruit contains a high amount of sugar, vitamin C, potassium, and the serotoninergic amino acid tryptophan, and is a good source of carbohydrates, proteins, and fats. It is recommended as a good source of raw fats by several raw food advocates while others classify it as a high-glycemic or high-fat food, recommending to minimise its consumption. Discover magazine reported an incident where a woman with preexisting renal failure ate a durian and ended up critically ill from potassium overdose.

Plant Cultivation
Durian trees are relatively large, growing to 25–50 m in height, depending on species. The leaves are evergreen, opposite, elliptic to oblong and 10–18 cm long. The flowers are produced in three to thirty clusters together on large branches and directly on the trunk, each flower having a calyx (sepals) and five (rarely four or six) petals. Durian trees have one or two flowering and fruiting periods each year, although the timing of these varies depends on species, cultivars and localities. A typical durian tree can bear fruit after four or five years. The durian fruit, which can hang from any branch, matures in about three months after pollination. Among the thirty known species of Durio, so far nine species have been identified as producing edible fruits: D. zibethinus, D. dulcis, D. grandiflorus, D. graveolens, D. kutejensis, D. lowianus, D. macrantha, D. oxleyanus and D. testudinarum. However, there are many species for which the fruit has never been collected or properly examined, and so other species with edible fruit may exist.

D. zibethinus is the only species commercially cultivated on a large scale and available outside of its native region. Since this species is open-pollinated, it shows considerable diversity in fruit colour and odour, size of flesh and seed, and tree phenology. In the species name, zibethinus refers to the Indian civet, Viverra zibetha. There is disagreement regarding whether this name, bestowed by Linnaeus, refers to civets being so fond of the durian that the fruit was used as bait to entrap them, or to the durian smelling like the civet.

Durian flowers are large and feathery with copious nectar, and give off a heavy, sour and buttery odour. These features are typical of flowers which are pollinated by certain species of bats while they eat nectar and pollen. According to a research conducted in Malaysia during 1970s, durians were pollinated almost exclusively by cave fruit bats (Eonycteris spelaea). However, a more recent research done in 1996 indicated that two species, D. grandiflorus and D. oblongus, were pollinated by spiderhunters (Nectariniidae) and that the other species, D. kutejensis, was pollinated by giant honey bees and birds as well as bats.

In Indonesia, durian is available in December–January.

Propagation
Seed, layering, marcotting, or more commonly, by grafting, including bud, veneer, wedge, whip or U-grafting onto seedlings of randomly selected rootstocks.

Varieties
Matahari, Monthong.

Area of Production
West Java, Central Java, East Java, North Sumatra, South Sumatra, Kalimantan.

Mangosteen: Xanthones (1/5)










Xanthones are biologically active plant phenols found in a few select tropical plants. Current research on xanthones suggests they are beneficial in helping with many conditions including: allergies, infections (microbial, fungus, viral), cholesterol levels, inflammation, skin disorders, gastro-intestinal disorders, and fatigue.

Xanthones have been found to support and enhance the body's immune system. Xanthones also exhibit strong antioxidant activity which is beneficial for neutralizing free radicals in the body.


Facts about xanthones:
  • The most plentiful natural source of xanthones is the mangosteen (Garcinia mangostana), which contains over 30 xanthones. The mangosteen has by far the most xanthones of any plant. The pericarp of the mangosteen fruit contains the vast majority of the xanthones.
  • Xanthones are some of the most potent antioxidants known. It is thought to be more potent than both Vitamin C and Vitamin E. In fact, many doctors refer to xanthones as "Super Antioxidants."
  • Xanthones are heat stable molecules. Unlike proteins, they won't denature or lose their structure when heated.

Banana







Scientific Name : Musa spp.
Local Name : Pisang
Other Common Name : Banananen (German), Banano (Spanish)

Origin
Native to Southeast Asia and Australia.

Uses
Normally eaten fresh, puree. Some varieties are generally cooked first (fried, boiled, baked or chipped).

Nutrient Content
Banana is a good source of kalium and phosphor. Kalium is an important mineral required by nervous and muscle systems. So if it is consumed together with milk, it can generate effects that calm nerves. Besides containing various vitamins (vitamins A, C, B1, B2, and B6), banana is a good source of instant energy because of its high degree of natural sugar that is easy to absorb.

Plant Cultivation
The banana plant is a pseudostem that grows to 7.6 m tall, growing from a corm. Leaves are spirally arranged and may grow 2.7 m long and 60 cm wide. Each pseudostem would produce a bunch of yellow, green, or even red bananas before dying and being replaced by another pseudostem. Banana plant likes fertile soil. Ideal temperature is between 21-32 C.

The banana fruit grows in hanging clusters, with up to 20 fruits to a tier (called a hand), and 3-20 tiers to a bunch. The total of the hanging clusters is known as a bunch, or commercially as a "banana stem", and can weigh from 30–50 kg. The fruit averages 125 g, of which approximately 75% is water and 25% dry matter content. Each individual fruit (known as a banana or 'finger') has a protective outer layer (a peel or skin) with a fleshy edible inner portion.

In Indonesia, banana is available all year round, varieties Barangan is available in January–June.

Propagation
Sucker, tissue culture.

Varieties
Mas Kirana, Raja Bulu, Barangan, Cavendish, Tanduk, Ambon, Susu, Kepok.

Area of Production
West Java, Central Java, East Java, Lampung, North Sumatra, South Sumatra, Kalimantan.

Exports
Japan, Hongkong, China, Singapore, Saudi Arabia, Australia, The Netherlands, United States, France.

Mangosteen: Queen of Fruits














Scientific Name : Garcinia mangostana L.
Indonesian Name : Manggis
Other Common Name: Manggistan (Dutch), Mangoustanier (French), Mangostan (German), Mangostino (Spanish), Mangostano (Italian)

Origin
Native to Sunda Islands and the Moluccas, Southeast Asia.

Uses
Normally eaten fresh, juice.

Nutrient Content
Mangosteen is typically advertised and marketed as part of an emerging category of novel functional foods sometimes called "superfruits" presumed to have a combination of 1) appealing subjective characteristics, such as taste, fragrance and visual qualities, 2) nutrient richness, 3) antioxidant strength and 4) potential impact for lowering risk against human diseases.

When analyzed specifically for its edible aril, mangosteen meets only the first criterion above, as its overall nutrient profile is absent of important content, it contains no pigmentation (correspondingly, no antioxidant phytochemicals in significant concentration) and there is no scientific evidence of aril constituents having any health properties.

Should puree or juice from the arils be infused with exocarp phenolic extracts, mangosteen juice adopts the purple color and astringency of its exocarp pigments. It is usually balanced for taste with sweeteners possibly requiring juices from other fruits.

Plant Cultivation
The tree grows from 7 to 25 meters tall. The rind (exocarp) of the edible fruit is deep reddish purple when ripe. Botanically an aril, the fragrant edible flesh is sweet and creamy, citrusy with some peach flavor. Mangosteen is closely related to other edible tropical fruits such as button mangosteen and lemondrop mangosteen. They like fertile, well draining soil. Ideal temperatures are between 25-32 C. Young trees may need some shelter by other trees, like banana tree. After 6-8 months, shelter can be reduced to full sun. Fruits take around 120-150 days to mature. In Indonesia, fruits available in October-April.

Propagation
Seed, top grafting, and approach grafting

Varieties
Kaligesing, Wanayasa, Seedless, Lingsar (White Mangosteen)

Area of Production
North Sumatra, West Sumatra, Jambi, South Sumatra, Bangka-Belitung, West Java, Central Java, East Java, Bali, West Nusa Tenggara

Export
Taiwan, Japan, China, Netherland, Hongkong, Middle Eastern.
