Tongkat ali extract solubility

The active ingredients of tongkat ali are quassinoids.[1]. Quassinoids are natural plant chemicals that belong to a larger group of plant chemicals named terpenoids.[2]. Terpenoids are lipids. [3] Lipids is the scientific name for fats. Fats are, as a rule of thumb, not soluble in water. (One of the biological important characteristics of fats, and lipids in general, is their insolubility in water. [4] ). Lipids bound to protein to form lipoproteins[5]. That happens all the time in nature and the human body.[6] In the human body, fats have to be bound to proteins so that they can be transported in the blood stream.[7] The exact form in which quassinoids are attached to other substances in the tongkat ali root has not been researched. But they are not isolates. When extracted with water and heat, the quassinoids disattach from the root tissue, just as the fat in a chicken leg disattaches when the chicken leg is cooked. The chicken fat swims on top of the water. The fat isn’t dissolved in the water. It’s the same for the quassinoids of tongkat ali root. That the quassinoids can be extracted by water doesn’t mean that the extract would be soluble in water. If the water is removed after extraction, there will be an oily film sticking to the dish, just as in the case of chicken fat after a chicken leg has been boiled.

The extraction process used water, but that doesn’t mean that the resulting product would have a high degree of solubility.

We at Sumatra Pasak Bumi have a definite problem with fakers of our products. Some claim that their own 1:200 tongkat ali extract is of superior quality and superior purity, and cite as proof that their substance is fully water-soluble. But if their substances are fully water-soluble, then they are not quassinoids, and if they aren’t quassinoids they are also not tongkat ali.

The differential anti-proliferation effect of white (Pueraria mirifica), red (Butea superba), and black (Mucuna collettii) Kwao Krua plants on the growth of MCF-7 cells

The differential anti-proliferation effect of white (Pueraria mirifica), red (Butea superba) and black (Mucuna collettii) Kwao Krua plant extracts on the growth of MCF-7 cells was evaluated after 4 days of incubation. The percent cell growth comparison was based on protein determination of the harvested cells in parallel with the control group and Pueraria lobata treatment group. Pueraria lobata led to no proliferation and a mild anti-proliferation effect on the growth of MCF-7 cells. Pueraria mirifica caused proliferation at 1 μg/mL and an anti-proliferative effect on the growth of MCF-7 cells at 100 and 1000 μg/mL with an ED50 value of 642.83 μg/mL. Butea superba led to no proliferation and an anti-proliferation effect on the growth of MCF-7 cells at 10, 100 and 1000 μg/mL with an ED50 value of 370.91 μg/mL. Mucuna collettii led to no proliferation and an anti-proliferation effect on the growth of MCF-7 cells at 100 and 1000 μg/mL with an ED50 value of 85.36 μg/mL. The results demonstrated that only Pueraria mirifica showed an estrogenic effect on MCF-7 cell growth and a clear antagonistic effect with E2 at high concentration. Butea superba and Mucuna collettii exhibited only anti-proliferation effects on the growth of MCF-7 cells in relation with a possible anti-estrogen mechanism or a potent cytotoxic effect.
