Isoflavones and phenols are both present in soybeans.
Phenols are the basic building block of many plant constituents; many different phenolic compounds exist that are based on it. One such compound is salicylic acid, which is often combined with a sugar to form glycoside that is antiseptic. Saponins are glycosides. The steroidal saponins mimic the precursers of female sex hormones, and the tri-terpenoid saponins mimic the adrenal hormone ACTH. Saponins are present in small amounts in soybeans. Isoflavones are very similar in structure to estrogen.
Phenols have a low acidity.
Soy lecithin typically does not contain significant amounts of isoflavones. Lecithin is primarily a fat extracted from soybeans, and the process of extracting lecithin usually removes most of the isoflavones, which are a type of phytoestrogen found in whole soy products. Therefore, while soy lecithin is derived from soy, it is not a notable source of isoflavones.
Phenols give a positive test.

Only if it's smoked - pork is naturally free from phenols, but the smoking process adds them.
A positive test for phenols using ferric chloride is recognized by the formation of a colored complex. When phenols react with ferric chloride, a deep purple or blue color indicates the presence of phenols. This color change occurs due to the formation of an iron-phenol complex.
Types of phenols found in industrial wastewater include cresols, pentachlorophenol, bisphenol A, and chlorophenols. These compounds can be toxic to aquatic life and can cause environmental damage if released untreated into water bodies.
