Bioactive compounds present in different parts of Guava and their significance: A review

Abstract

Guava (Psidium guajava L.) is a tropical and subtropical fruit crop that is commonly used in food and traditional medicine all over the world. It is a member of the Myrtaceae family. Tannins, flavonoid: quercetin, pentacyclic triterpenoid: guajanoic acid, saponins, carotenoids, lectins, leucocyanidin, uvaol, amritoside, betasitosterol, ellagic acid, oleanolic acid, triterpenes, and ursolic acid are some of the essential phytoconstituents. Guava can be eaten raw or refined into juice, pulp, jam, jelly, nectar, powder, tea, and other items. The guava plant parts are utilized for the improvement of variety industrial and medicinal products. Antiviral, anti-inflammatory, antidiabetic and anti-mutagenic factors are all found in guava. Guava extract has antinociceptive properties and can help with liver inflammation and serum development.

Effect of different growing media and growing conditions on seed germination of guava and nutrients content of guava seedlings

“…This could be because a greenhouse permits air to press closer to the foliage for peak photosynthesis and carbon dioxide concentration. Similar results were also reported by Sharma et al (2020) [10] in guava. Also due to higher relative humidity in polyhouse as compared to open field conditions.…”

“…It is susceptible to frost. It is quite a hardy, prolific bearer and considered to be one of the most delicate nutritionally valuable and remunerative crops of the tropics (Sharma et al, 2020;Singh et al, 2000) [10,12] . Since in Haryana guava is a remunerative crop, the area under guava cultivation is increasing day by day.…”

Postharvest Physiology and Handling of Guava Fruit

“…In addition, guavas contain diverse bioactive compounds, including tannins, flavonoids, pentacyclic triterpenoids, carotenoids, and polyphenols. These bioactive constituents have been found to provide anticancer and anti-inflammatory benefits, protect the heart and eyes, and regulate blood sugar [ 3 , 4 , 5 ].…”

In vitro antibacterial activity of betulinic acid from Psidium guajava L

“…(Ryu, 2012) [3] . The primary biochemical constituents of guava include triterpene acids, sesquiterpene alcohols, flavonoids, and essential oils (Shivani and Anjan, 2021) [4] . With more than 14,000 known structures, triterpenoids are a diverse subclass of terpenoids with structural variety.…”
