Ionone belongs to rose ketone and exists in a variety of flower essential oils including rose essential oil. β- Ionone is the main contributor of rose aroma, although its content in essential oil is relatively low. Violet is an important spice chemical used in perfumes, spices and condiments. Ionone comes from the degradation of carotenoids in organisms.

It is mainly used in perfume, high-grade cosmetics, soap and essence. A small amount is used in food essence.

Saponin are a class of glycosides (polysaccharides) with complex structure, which are widely distributed in the plant kingdom (Rosaceae, Caryophyllaceae, dioscoreaceae, etc.). Its aqueous solution can produce persistent soap similar to soap. According to the basic chemical structure of saponins, they can be divided into two types: steroidal saponins (in digitalis, with cardiotonic effect) and triterpenoid saponins (in saponin root and soap skin, without cardiotonic effect). Saponin is used in light industry, chemical industry, pesticide, feed, breeding, textile, oil extraction, mining, building materials and highway construction. It is mainly used as emulsifier, foaming agent and preservative. It is also an intermediate in the manufacture of steroidal drugs.

Melanin is a natural product found in Streptomyces parvulus, Streptomyces albidoflavus, and other organisms with data available.

Vitamin B6 is also known as the "" anti dermatitis vitamin "". One of the B vitamins. Genus pyridoxine derivatives, including pyridoxine, pyridoxal, pyridoxamine, and three compounds, which exist in food in a form that can interconvert. But vitamin B6 in plants is mostly pyridoxine, while it is mostly pyridoxal and pyridoxamine in humans and animals. Human intestinal bacteria can also synthesize pyridoxine, in humans pyridoxine can be converted into pyridoxal and pyridoxamine, while the latter two cannot be converted into pyridoxine. All three have the same physiological activity. Vitamin B6 is rapidly converted to pyridoxal phosphate in humans, and this compound plays an important role in amino acid metabolism as a coenzyme for decarboxylase, transaminase, kynureninase, deaminase, and desulfhydrase. It is also an essential coenzyme for carbohydrate and fat metabolism, activity of the central nervous system, and haemoglobin production.
