These chemical compounds work by neutralizing free radicals and preventing oxidative stress within biological systems. Research indicates that the extracts from Rosa chinensis can significantly inhibit lipid peroxidation and protect cellular structures from damage. Furthermore, the plant's ability to modulate enzymatic defenses supports its potential use in managing inflammation-related conditions. Such properties make it a valuable subject for developing natural therapeutic agents.
According to a study published by "Heliyon", the Chongqing Old Rose variety shows enriched pathways for flavonoid biosynthesis, monoterpenoid biosynthesis, and phenylalanine metabolism. The predominant anthocyanins found in this plant are cyanidin and peoniidin, which indicate its antioxidant potential. It contains aromatic compounds and terpenoids including 2-phenylethanol, linalool, geraniol, and caryophyllene α-oxide, providing a natural basis for essential oil extraction. Furthermore, the presence of phenols, steroids, and alkaloids suggests the plant has potential for medicinal and edible applications.

What medicinal compounds this plant contains?
This plant contains medicinal compounds such as 2-phenylethanol, anthocyanins, flavonoids, peoniidin, and phenols. These chemical constituents contribute to the various therapeutic properties associated with the species. The presence of phenols and flavonoids provides significant antioxidant activity within the plant tissues. Additionally, the anthocyanins and peoniidin are responsible for the vibrant pigments while offering further biological benefits. The aromatic compound 2-phenylethanol also plays a key role in the plant's unique chemical profile.
According to a study published by "Scientific reports", Rosa chinensis leaves contain anthocyanins, which are primarily cyanidin, during the red and young stage of development. These anthocyanins are abundant in both the adaxial and abaxial epidermal cells when no cuticular wax is observed. As the leaves develop and turn green, the content of anthocyanins gradually decreases until they have completely disappeared from the leaves. During the later stages of development, the content of cuticular wax increases significantly on both the adaxial and abaaxial epidermis. Analysis using gas chromatography-mass spectrometry (GC-MS) identified that alkanes and esters are the most prominent components present in the leaf waxes of Rosa chinensis.
The primary medicinal compounds of this plant are shown in the list below.
- 2-phenylethanol
- anthocyanins
- flavonoids
- peoniidin
- phenols
