What is Rhapontin?

Rhaponitin, also known as poniticin, is a chemical compound with the molecular formula C21H24O9. It is a derivative of stilbene and belongs to the group of stilbene glycosides. While the Chinese Pharmacopoeia 2005 Edition does not mention rhaponitin, recent studies have demonstrated its various pharmacological activities.

Some of the reported benefits of rhaponitin include antibacterial properties, improved microcirculation, reduced blood lipids and blood sugar levels, anti-tumor effects, inhibition of allergic reactions, modulation of the immune system, anti-thrombotic properties, and antioxidant effects. Additionally, its metabolites, such as lefacidin, have shown a range of pharmacological activities.

Lefacidin, a metabolite of rhaponitin, has been found to act as an agonist of PPAR-γ, which helps in reducing blood glucose levels and treating diabetes. Its efficacy in lowering blood sugar levels is comparable to that of the drug pioglitazone, a thiazolidinedione. This makes lefacidin a promising candidate for the development of a highly effective diabetes drug with minimal side effects, derived from natural sources.

Rhapontin Uses

A study conducted by various medical institutions including Gansu Provincial People’s Hospital, Air Force Lanzhou Hospital, and Lanzhou Railway Central Hospital has confirmed the effectiveness of Lepangting tablets in treating hyperlipidemia. This includes conditions such as hypertriglyceridemia, hypercholesterolemia, and hyperlipoproteinemia in 30 clinical cases.

Furthermore, research carried out by the Geriatric Medicine Research Group at Tongji Medical University involved 92 elderly individuals who took Lepangting tablets at a dosage of 20mg three times a day for three months. The study found a significant 28.10% reduction in lipid peroxide levels compared to before taking the medication.

In another study by the same research group, 124 subjects aged 50-70 years old underwent various tests to assess their physical and cognitive abilities. After three months of taking Lepangting tablets at a dosage of 20mg three times a day, improvements were observed in tests measuring flexibility, balance, and memory. Patients with conditions such as coronary heart disease and hypertension also reported positive effects, including reduced chest tightness, fewer angina attacks, and stabilized blood pressure.

Overall, clinical trials and observations have shown that Lepangting tablets have anti-aging properties, leading to improvements in lipid levels, immunity, and overall health in middle-aged and elderly individuals.

Rhapontin Preparation

The roots and rhizomes of Hetao rhubarb are crushed and extracted with 95% (v/v) ethanol aqueous solution in a weight to volume ratio of 1:3. The extraction process is carried out three times using flash extraction for 1.5 minutes each time. The extracts are then filtered and combined to obtain the total extract of rhubarb.
The extract is then suspended in water and extracted three times with petroleum ether/ethyl acetate (2:1, v/v) to separate the lipids from the soluble components. The aqueous phase, containing the soluble components, is reserved.
The remaining aqueous phase, after filtering out the fat-soluble components, contains the crude Rhapontin filter cake.
The crude Rhapontin is recrystallized using 75% (v/v) ethanol aqueous solution and then vacuum freeze-dried to obtain the pure Rhapontin product.
