Rhodiola

Rhodiola rosea
On Tibetan plateau, the high altitude area rise some 13,000 feet (4 kilometers) above sea level, where travelers to the high plateaus possibly suffer acute hypoxia, a condition created by a diminished supply of oxygen to body tissues. At high altitudes, the air is much thinner than at sea level. In consequence, a person inhales fewer oxygen molecules with each breath.
Symptoms of hypoxia, sometimes known as mountain sickness, include headaches, vomiting, sleeplessness, impaired thinking, and an inability to sustain long periods of physical activity.
How residents survive in such harsh environment?

In Tibetan plateau, there is a kind of perennial plant called Rhodiola rosea. Growing in cold, oxygen deficit, drought environment with diurnal temperature variation and strong UV radiation, Rhodiola has tenacious vitality. It was therefore praised in ancient medical books as “immortal grass” or “Nine dead resurrection grass.” Rhodiola rosea contains multiple functional components including hydrophilic and hydrophobic ingredients. Most extraction skills, however, can get only hydrophilic ingredients like gallic acid, salidroside, and tyrosol. The hydrophobic ingredients of Rhodiola, like polyphenol or flavonoids were scarcely being extracted and make it a waste.

 

Multi-polarity extraction system (MPES)
The extraction efficiency is closely related to the solvent polarity. Only the functional ingredients with similar polarities with the solvent can be extracted successfully. Extract with only hot water or ethanol, many active components would be neglected.
Dalong Biotechnology extracts the essence of Rhodiola with Multi-polarity extraction system (MPES). All the functional components are thus elicited from the herbs. The complete value of the extracted materials is brought into full play. Rhodiola rosea from Dalong Biotech are therefore more absorbable than the crude drug Rhodiola powder on the market, and with better effect to human health.

 

The functional ingredients of Rhodiola rosea

  • Salidroside, Tyrosol

    Salidroside and Tyrosol are specific nutrients from Rhodiola and key elements that allow Rhodiola to survive in cruel environment. Keeping on taking the nutrients are good for modern people with suboptimal health.

  • Rhodiola polyphenols

    In Dalong, the polyphenols extracted from Rhodiola are much more than Rhodiola on the market. Polyphenols help maintain health, young, and beautiful.

  • Flavonoids

    In biosphere, propolis contains highest amount of flavonoids and Rhodiola also contains flavonoids. It was proved that flavonoids can regulate physical function and promote metabolism.

  • Rutin

    Rutin is a bioflavanoid found in the rind of green citrus fruits and in rose hips and black currants. Rutin have been used to support blood circulation.

  • Gallic acid

    Gallic acid occurs as a free molecule or as part of a tannin molecule. It is an organic acid found in a variety of foods and herbs. Many of the foods containing Gallic acid have been used for years as natural remedies, and were relied upon by various cultures for their medicinal properties. Today, Gallic acid is believed to have health benefits. Rhodiola is rich in gallic acid. Modern people, under huge pressure and with unbalanced diet, the body is usually acidic. Long term use of gallic acid is good for nutritional supplements.
