Production of pilocarpine in callus of jaborandi (pilocarpus microphyllus stapf)

In Vitro Cellular and Developmental Biology - Plant, 2005
Summary Jaborandi (Pilocarpus microphyllus) is the only known source of pilocarpine, and although this alkaloid is the only natural compound used to treat glaucoma, very little is known about its metabolism. Calluses obtained from petioles of P. microphyllus leaves were partially immersed in MS (Murashige and Skoog) liquid medium containing different ...

Jaborandi (Pilocarpus sp., rutaceae): A wild species

Economic Botany, 1997
Jaborandi (Pilocarpus sp.;) is a shrub or small tree 3-7.5 m tall that can be found in native stands or as isolated individuals throughout Brazil. The leaves of jaborandi contain the alkaloid pilocarpine, widely used in ophthalmology for treatment of certain types of glaucoma and more recently for xerostomia. This paper discusses the current systems of

Evolution of phytochemical diversity in Pilocarpus (Rutaceae)

Phytochemistry, 2019
The evolution of phytochemical diversity and biosynthetic pathways in plants can be evaluated from a phylogenetic and environmental perspective. Pilocarpus Vahl (Rutaceae), an economically important medicinal plant in the family Rutaceae, has a great diversity of imidazole alkaloids and coumarins. In this study, we used phylogenetic comparative methods

New Coumarins fromPilocarpus goudotianus

Planta Medica, 1990
The leaves of PILOCARPUS GOUDOTIANUS afforded in addition to eight known coumarins three new ones, donatin, alloxanthoxyletol, and (+)-elisin. The structures were elucidated on the basis of spectroscopic evidence and chemical derivatives.

Phytochemical and antimicrobial study of Pilocarpus pennatifolius Lemaire

Fitoterapia, 2018
The investigation of the crude extract of leaves and bark of Pilocarpus pennatifolius Lemaire allowed isolated of a not yet described coumarin, together with three known coumarins (bergapten, xanthotoxin and dimethyl allyl xanthyletin), and a not yet described imidazole alkaloid.

Reference genes for quantitative RT-PCR of the pilocarpine producer Pilocarpus microphyllus and two other Pilocarpus species

Theoretical and Experimental Plant Physiology, 2017
Members of the genus Pilocarpus are the only natural source of the imidazole alkaloid pilocarpine, a plant metabolite widely used in the pharmaceutical industry. Although there is variation in the pilocarpine content in Pilocarpus, only the species Pilocarpus spicatus does not have pilocarpine, although it contains other imidazole alkaloids related ...

3-Methoxyfurocoumarins from Pilocarpus riedelianus

Phytochemistry, 1993
Abstract The stems of Pilocarpus riedelianus have afforded the new angular furocoumarins 3-methoxyangelicin and 3,6-dimethoxyangelicin, in addition to the known sphondin, pimpinellin, scopoletin, aurapten, osthol and meranzin hydrate. Their structures were elucidated on the basis of spectral data.

Epiisopiloturin, ein neues Pilocarpus‐Alkaloid

Archiv der Pharmazie, 1978
AbstractVon Pilocarpus microphyllus Stapf gibt es eine Varietät, die außer dem Hauptalkaloid Pilocarpin anstelle des üblichen Nebenalkaloides Pilosin eine neue, isomere Base enthält. Von den vier möglichen Stereoisomeren des Pilosins sind bisher drei bekannt: Pilosin, Isopilosin und Epiisopilosin.
