The disclosed technology generally relates to a method for isolating bioactive components from Eurycoma longifolia (Tongkat Ali). In one aspect, the methods comprise preparing a Eurycoma longifolia extract by a continuous-flow evaporation process. The disclosed technology further relates to highly purified extracts comprising Eurycoma longifolia, composition comprising extracts of Eurycoma longifolia, and uses of such extracts and compositions. The compositions, in particular, are useful for increasing testosterone levels and supporting natural stamina, endurance, and strength.
Tongkat Ali, also known as Eurycoma longifolia, pasak bumi, long jack, or Malaysia ginseng, belongs to the Simaroubaceae plants. Alternative names include penawar pahit, bedara pahit, tongkat baginda, petala bumi, setunjang bumi, cay ba binh, and plaa-lai-pueak. Tongkat Ali is a slow-growing tropical rain forest plant, mainly found in Myanmar, Thailand, Malaysia, Vietnam, and China's Hainan Island.
The chemical constituents isolated from different parts of Tongkat Ali are mainly diterpenoids containing iron lignin skeleton and iron indole ketone alkaloids such as eurycomaoside, eurycolactone, eurycomalactone, eurycomanone and pasakbumin-B. In addition, it also contains biphenyl lignin, squalene derivatives, active polysaccharides, glycopeptides and various amino acid.
The roots and/or stems of Tongkat Ali (or extracts of these roots and/or stems) have been used in traditional and folk medicine either as a single herb or as part of multiple herb ingredients to treat dysentery, fever, malaria and sexual problems including male infertility. Tongkat Ali's functions relate to treating hypertension, scabies, jaundice, carbuncles, skin itching, malaria, diarrhea, mouth ulcers, headache and other diseases. Tongkat Ali also has the effect of enhancing male sexual function and treating male sexual dysfunction. For example, European Patent No. EP1952816 discloses a Tongkat Ali extract that has the effect of treating male sexual dysfunction. Malaysian Patent No. MY2006PI03783 disclosed the efficacy of Eurycoma longifolia polar organic solvent extract for promoting growth of sperm, improving sperm quality, and other aspects of the treatment of infertility. Japanese Patent No. JP2012092108 discloses that a Tongkat Ali root extract can be prepared as a medicine for external use for treating male sexual dysfunction. Chinese Patent No. CN102430038 discloses compositions containing Tongkat Ali can increase blood levels of testosterone. Additionally, recent studies have shown that this plant extract contains quassinoids, which also has good anti-tumor and anti-HIV effects.
Tongkat Ali extracts also may be useful for weight control. For example, U.S. Patent Publication No. 2007/0224300 discloses compositions comprising Tongkat Ali extracts that may be used to promote weight loss and help dieters maintain weight loss. Malaysian Patent No. 142166 discloses substances extracted from Eurycoma longifolia useful for treating obesity and diseases associated with obesity.
There are several existing methods to extract eurycomanone from Tongkat Ali. For example, CN103408564B and CN201610743803.5 disclose extraction and purification processes of eurycomanone from Tongkat Ali. However, these techniques extract insufficient biochemically-effective components, take a long time and use a lot of organic solvent. The low production capacity and high production cost make them unsuitable for large-scale production. Accordingly, there is a need for processes that more efficiently prepare Tongkat Ali extract, and that produce an extract that is enriched in eurycomanone.
To overcome prior the above-mentioned deficiencies in methods for preparing Tongkat Ali extract and to obtain extracts with higher concentrations of eurycomanone, it is an objective of one aspect of the disclosed technology to develop techniques that are simple, quick, pollution-free, suitable for large-scale production, and entail low energy consumption and low cost.
In some embodiments, Tongkat Ali extracts comprise quassinoids, which include eurycomanone, 13α,21-dihydroeurycomanone, 13(21)-epoxyeurycomanone, eurycomanol and its glycoside, eurycomaoside and its aglycone, including all their analogues and derivatives; and coumarins, which include 6-methoxycoumarin-7-O-σ-D-glycopyranoside, its other glycosides, analogues and derivatives.
