Saponins, tannins, terpenoids, alkaloids, steroids, flavonoids, and phenolic compounds are present while cardiac glycosides
are absent in the methanol extract of Erythraea ramosissima.
cordifolia was performed for the qualitative analysis of alkaloids by Sethi  and Wagner method , reducing sugars by Fehling method , terpenoids by Harborne method , tannins by Evans method , saponins by Akinjogunla methodology  flavonoids by Bello  and Mace strategy , cardiac glycosides
by Onwukaeme strategy  and anthraquinones by Evans method .
are chemically similar to digoxin, and are distributed throughout the plant, either fresh or dried (LANGFORD & BOOR, 1996; SOTO-BLANCO et al.
were present in all the substrates while absent in black gram pods (Table 3).
The phytochemical screening of the fresh fruit, decoction, crude ethanolic, aqueous, hexane, and ethyl acetate extracts was carried out to determine the presence of alkaloids, flavonoids, reducing sugars, cardiac glycosides
, saponins, phytosterols, tannins, and triterpenes with the procedures described by Tiwari et al .
Acute yellow oleander (Thevetia peruviana) poisoning: cardiac arrhythmias, electrolyte disturbances, and serum cardiac glycoside
concentrations on presentation to hospital.
Milky wax exuding from the stem contains cardiac glycosides
(calotropin, uscharin) and fatty acids.
The results obtained from the phytochemical screening of the extract in Table 1 agrees with those reported by Ogundare and Onifade (2009) and Patience and Godwin (2010) which stated that phenolics, alkaloids, cardiac glycosides
, flavonoids, terpenoids, and steroids are present in the methanolic extract of A.
Toxicity may occur after consuming teas brewed from plant parts or after consuming leaves, flowers or seeds from plants containing cardiac glycosides
Microbiological exploitation of cardiac glycosides
and alkaloids from Garcinia kola, Borreriao cymoides, Kola nitida and Citrus aurantifolia.
Hypothesis: It was previously reported that Cardiac glycosides
possessed antitumor activity by inducing apoptosis of multiple cancer cells through oxidative stress.
First described in 1785 by William Withering, cardiac glycosides
have been used in the treatment of heart failure for > 200 years,  and digoxin had been the most commonly used of these compounds.
The cardiac glycosides
therapeutically have the capability to enhance the power of the heart beat without any increase in the amount of oxygen required by the heart muscle.
However, chronic use of cardiac glycosides
has several limitations, including a low therapeutic index, difficulty in therapeutic drug monitoring, and the propensity to induce arrhythmias.
The aqueous extract of green tea was subjected to qualitative analysis for the following organic plant constituents: alkaloids, proteins amino acids, anthraquinones, flavonoids, carbohydrates, saponins, tannins, steroids, triterpenoids, and cardiac glycosides
[10,11] (Table 1).
