Indole Alkaloids of Acer saccharinum (the Silver Maple), Dictyoloma incanescens, Piptadenia colubrina, and Mimosa hostilis

Abstract

Gramine was isolated from the leaves of Acer saccharinum L., JV,M-dimethyl-5-methoxytryptamine from the bark of Dictyoloma incanescens D.C., bufotenine from the seeds of Piptadenia colubrina Benth., and N, V-dimethyltryptamine from the roots of Mimosa hostilis Benth.Several plants which we have studied recently have, by coincidence, yielded indole alkaloids of simple structure. Four of these are described in the present paper.

Inhibitive action of gramine towards corrosion of mild steel in deaerated 1.0M hydrochloric acid solutions

“…This has been employed specifically in the field of corrosion, resulting in the decreased use of toxic inhibitors and the development of new environmentally friendly ones. Gramine, which occurs in different plant species such as in the sprouting barley and acer saccharinum, is a natural product at low environmental impact and is typical of the simpler indole alkaloids [39]. The aim of the present study was to study the inhibiting action of the gramine on the corrosion of mild steel in deaerated 1.0 M hydrochloric acid solutions in the temperature range of 25-55°C.…”

Distribution of alkaloids in woody plants

“…In addition to synthesizing phenethylamine alkaloids (DMT, bufotenine), the yopo (Anadenanthera peregrina), a South American tree that looks like Acacia, produces indole alkaloids called bcarbolines such as harmine, harmaline, elaeagnine and tryptoline (Table 1) (16,17). It has been reported that other woody species also accumulate b-carboline alkaloids including the maple tree (Acer saccharinum) which produces harmine and elaeagnine and the simarouba tree (Simarouba glauca) which synthesizes cathin-6-one and others b-carbolines derivatives (Table 1) (18)(19)(20). Alkaloids in the Rutaceae family including canthin-6-one, isolated from bark and leaves of Zanthoxylum has cytotoxic and anti-tumor properties (20).…”

Flavonoides e outros compostos isolados de Mimosa artemisiana Heringer e Paula

“…15 Algumas tribos indígenas utilizam espécies de Mimosa no preparo de bebidas alucinógenas em rituais místicos e religiosos. 16,17 Este é o primeiro estudo fitoquímico da espécie M. artemisiana e as substâncias (3), (4) e (5) estão sendo descritas pela primeira vez neste gênero. Além disso, o presente trabalho descreve o isolamento e a identificação dos flavonoides (1-3), das flavonolignanas (4) e (5) do esteroide glicosilado (6), do triterpeno lupeol (7), dos esteroides (8)(9)(10)(11)(12)(13), do metil-indol-3-carboxilato (14) e do indol-3-carboxialdeído (15) como forma de contribuição para o conhecimento sobre a química do gênero Mimosa L.…”
