Vilcacora [ Uncaria tomentosa ( Willd . ) DC . and Uncaria guianensis ( Aublet ) Gmell . ] – a review of published scientific literature

  title={Vilcacora [ Uncaria tomentosa ( Willd . ) DC . and Uncaria guianensis ( Aublet ) Gmell . ] – a review of published scientific literature},
  author={• A.Rich. and • Willd. and Baillon},
Uncaria tomentosa (Willdenow ex Roemer and Schultes) DC. and its relative Uncaria guianensis (Aublet) Gmell, both from the Rubiaceae family, are vines growing in jungles of South and Central America. They are widely used in folk and complementary medicine under traditional names: ‘Vilcacora’, ‘una de gato’, ‘cat’s claw“, „cat’s crew’, ‘saventaro’, ‘hawk’s claw’, ‘samento’, ‘garabato amarillo’ and ‘Katzenkralle’. In the genus Uncaria there are also other plants with well-known healing properties…

Comprehensive Review of the Components in Cat’s Claw (Uncaria tomentosa) and Their Antibacterial Activity
It is intended that this review will provide a substantiated, comprehensive collection of the known chemical constituents of U. tomentosa, including their detailed structures, and identify those components that offer some promise as antibacterials based on the research to date.
Genetic diversity among genotypes of Uncaria guianensis (Aubl.) J.F. Gmel. maintained in an in vitro germplasm bank
The results demonstrate that the genetic diversity within the in vitro germplasm bank is sufficient to support breeding studies, selection of elite genotypes and the large-scale multiplication of plants that could serve as feedstock for the industrial-scale production of phytomedicines.
The effect of Uncaria tomentosa bark water extract on chemokinetic activity of spleen lymphocytes in mice
Organic solvent extracts of Uncaria were shown to have contraceptive, cytostatic, anti-inflammatory,Anti-mutagenic, pro-bacterial and anti-viral activities as well as a large range of bioactive secondary metabolites.
Phenolic Assesment of Uncaria tomentosa L. (Cat’s Claw): Leaves, Stem, Bark and Wood Extracts
The results confirmed the feasibility of U. tomentosa as a suitable raw material for obtaining phenolic- and alkaloid-rich extracts of potential interest.
Genetic structure and chemical diversity in natural populations of Uncaria guianensis (Aubl.) J.F.Gmel. (Rubiaceae)
The genetic data confirm the urgent need for conservation programs for U. guianensis, and for further studies aimed at ascertaining the genetic basis and heritability of alkaloid accumulation.
Isolation of mitraphylline from Uncaria tomentosa (Willd. ex Schult.) DC. barks and development of spectrophotometric method for total alkaloids determination in Cat's Claw samples.
The methods developed to obtain mitraphylline analytical standard from U. tomentosa barks and to determine total alkaloids by spectrophotometry provided a cheaper and faster quality control alternative for U.tomentosa samples.
eview review of the antioxidant potential of medicinal plant pecies
The literature reveals that these natural antioxidants represent a potentially side effect-free alternative to synthetic antioxidants in the food processing industry and for use in preventive medicine.
The Effect of Rutin and Extracts of Uncaria guianensis (Aubl.) J. F. Gmeland on Primary Endometriotic Cells: A 2D and 3D Study
In vitro effects of rutin and the aqueous bark, roots, and leaf extracts and isolated components of Uncaria guianensis on stromal cells from eutopic endometrium and lesions of patients with endometriosis and applied treatments did not reduce cellular viability, but ROS production did increase.

It was found that 2 chemotypes of Uncaria tomentosa with different alkaloid patterns occur in nature, and Mixtures of these 2 types of drugs are therefore unsuitable for medicinal uses.
Alkaloids from S. American species of Uncaria (Rubiaceae)
The morphological and chemical affinities between the different geographical groups of species are of interest in the light of divergent theories as to the origin of the Asian, African and S. American continents.

Morphological study and alkaloidal analysis of Uncaria scandens (Ribiaceae) from Nepal
Hooks with short stems of Uncaha spp. of the family Rubiaceae are called Diao-teng-gou, and have been used in Chinese medicine. The alkaloids contained are considered to be its effective components.

HS and beta-Y showed a preventive effect on the development of gastric erosions in mice and the potency of the antiarrhythmic effects induced by HS was approximately the same as that of ajmaline, an indole alkaloid.
Una de gato: fate and future of a Peruvian forest resource
Uncaria tomentosa and U. guianensis have been important in traditional healing in many South American countries. These species contain some sixty active substances which are widely tested for
Die Alkaloide von Uncaria tomentosa und ihre Phagozytose-steigernde Wirkung.
With the exception of mitraphyllin and rynchophyllin all alkaloids showed a pronounced enhancement effect on phagozytosis, determined in two IN VITRO tests and the IN VIVO-carbon clearance test.
Alkaloids and procyanidins of an Uncaria sp. from Peru.
The alkaloid and procyanidin composition of Uncaria sp. from eastern Peru, used in folk medicine was studied. Five alkaloids have been separated and identified as pteropodine, speciophylline,
