TEST FOR SAPONIN GLYCOSIDES Froth formation Test (foam) Place the 2 ml solution of drug in water in a test tube, shake well, stable froth (foam) is formed. Haemolysis test. Add 0.2 ml of solution of saponin (prepared in 1% normal saline) to 0.2 ml of blood in normal saline and mix well.
CARDIAC GLYCOSIDES These are an important class of naturally occurring drugs whose actions include both beneficial and toxic effects on the heart. Plant glycosides with specific action on heart. Historical use: to assasinate people, arrow poisons Historical sources: South American toad skins, African plant extracts Modern use: to treat congestive heart failure (dropsy). for treatment of atrial.
The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence the overall molecule's biological activity. Cardiac glycosides also vary in the groups attached at either end of the steroid.
Sea cucumbers produce numerous compounds with a wide range of chemical structural diversity. Among these, saponins are the most diverse and include sulfated, non-sulfated, acetylated and methylated congeners with different aglycone and sugar moieties. In this study, MALDI and ESI tandem mass spectrometry, in the positive ion mode, were used to elucidate the structure of new saponins extracted.
Obesity is one of the greatest public health problems. This complex condition has reached epidemic proportions in many parts of the world, and it constitutes a risk factor for several chronic disorders, such as hypertension, cardiovascular diseases and type 2 diabetes. In the last few decades, several studies dealt with the potential effects of natural products as new safe and effective tools.

A novel triterpenoid saponin, pittoviridoside (1), which possesses an unusual 2,3,4-trisubstituted glycosidic linkage, has been isolated from Pittosporum viridiflorum using the engineered yeast.
Lonicera japonica, known as Japanese honeysuckle and golden-and-silver honeysuckle, is a species of honeysuckle native to eastern Asia. It is often grown as an ornamental plant, but has become an invasive species in a number of countries. Japanese honeysuckle is used in traditional Chinese medicine.

The ash content of a crude drug is generally taken to be the residue remaining after incineration. It usually represents the inorganic salts naturally occurring in the drug and adhering to it, but it may also include inorganic matter added for the purpose of adulteration.
Tannin, also called tannic acid, any of a group of pale-yellow to light-brown amorphous substances in the form of powder, flakes, or a spongy mass, widely distributed in plants and used chiefly in tanning leather, dyeing fabric, making ink, and in various medical applications.Tannin solutions are acid and have an astringent taste. Tannin is responsible for the astringency, colour, and some of.Phenolic compounds are a group of phytochemicals, which have a phenol structure, i.e. an aromatic benzene ring bearing at least one hydroxyl substituent (Robbins 2003; Vermerris and Nicholson 2006).Phenolic compounds are commonly found throughout the plant kingdom, where they protect the plants from microbial infections, ultraviolet radiation and chemical stressors.Phytochemical Analysis of Medicinal Plants Used for the Management of Hypertension by Esan people of Edo State, Nigeria J.K.
