Plant Source: Rhodiola (also known as Arctic Root, Golden Root) is one of the plants of the genus Sedum, which is native to the Arctic Circle of Eastern Siberia. Rhodiola is widely distributed in the polar and mountainous regions of Europe and Asia. It grows more than 11,000 to 18,000 feet above sea level.
Extraction site: root
Origin: Rhodiola has nearly 100 species in the world, 70 species in China, 55 species in the Qinghai-Tibet Plateau, and 32 species in Tibet. It is distributed in the alpine regions of northeast, north, northwest and southwest China.
Rhodiola is a perennial herb that grows in areas with an altitude of 1600-4000 meters, such as alpine, dry, anoxic, strong ultraviolet radiation, and large temperature difference between day and night. It has strong environmental adaptability and vitality. The domestic application of Rhodiola is very early, and has been recorded in the "Four Medical Codes" and "Compendium of Materia Medica". Studies have shown that salidroside has various pharmacological effects such as anti-fatigue, anti-aging, immune regulation, and free radical scavenging. Shanghai Chuangsai provides salidroside, 10338-51-9, HPLC≥98%, commodity number: C78-A0076-20mg, 300 yuan
1. Enhance immunity
Rhodiola rosea restores normal immune system by improving T-cell immunity. It can improve the body's resistance to the accumulation of toxicosis
2. Eliminate depression
Rhodiola is used to enhance people's mental state and become a valuable medicine for those who live in countries and seasons that have not been exposed to sufficient sunlight due to the extension of the month.
3. Protect cardiovascular
Rhodiola rosea extract can alleviate cardiovascular damage and dysfunction caused by stress, prevent the decline of cardiac contractility secondary to ambient pressure in the frozen state and contribute to stable contraction.
4. Whitening, anti-radiation
Rhodiola extract, sweet and bitter. The main ingredients are salidroside and salidroside, and Rhodiola has been used in traditional herbs in the Carpathian Mountains of China, Siberia and Ukraine. In the Changbai Mountain area, local residents call it "longevity and old grass", and the Shennongjia area is also called "nine dead and still grass".
Active ingredients: phenylpropyl ester, rosavin (most active), rosin, rosarin, rhodilin, salidroside and its alum.
Preparation
Materials: column YMC I'sphere ODS-H (250 × 4.6 mm, 4 μm); mobile phase: methanol-water (15:85, V/V); injection volume: 20 μl; detection wavelength: 275 nm; flow rate: 1.0 Ml / min; column temperature: 35 ° C.
Method: 100 ml of the standard was taken, concentrated to dryness under reduced pressure, and 4 ml of methanol was added thereto, and dissolved by ultrasonication, and the filtrate was taken as a test solution. Another 10 mg of salidroside was placed in a 10 ml volumetric flask, dissolved in methanol and diluted to a volume to prepare a 1.0 mg/ml reference solution. The above reference solution and the test solution were respectively taken up on the same silica gel G thin plate by a capillary of 0.55 mm, and expanded upward with chloroform-methanol-acetone-water (6:3:1, V/V). To the exhibition distance of 18cm, take out and dry, and then use iodine fumigation for 2~3min to develop color. In the chromatogram of the test sample, the test sample should show the same color spot on the same position as the control.
