Psidium Guajava (Guava): A Plant of Multipurpose Medicinal Applications

Abstract

Shu et al. [26] isolated nine triterpenoids from guava fruit: ursolic acid; 1beta, 3beta-dihydroxyurs-12-en-28-oic acid; 2alpha,3beta-dihydroxyurs-12-en-28-oic acid; 3beta,19alpha-dihydroxyurs-12en-28-oic acid; 19a-hydroxylurs-12-en-28-oic acid-3-O-alpha-L-arabinopyrano- AbstractChronic degenerative diseases have reached epidemic proportions in industrialized and developing countries. Many studies have shown that plant can be helpful to prevent or treat diseases. Psidium guajava is a small medicinal tree that is native to South America and Brazil is among the world's top producers and most of the country's production is destined for the food industry. It is popularly known as guava and has been used traditionally as a medicinal plant throughout the world for a number of ailments. The aim of this review is to present some chemical compounds in P. guajava and their pharmacological effects. The main constituents of guava leaves are phenolic compounds, isoflavonoids, gallic acid, catechin, epicathechin, rutin, naringenin, kaempferol. The pulp is rich in ascorbic acid, carotenoids (lycopene, β-carotene and β-cryptoxanthin). The seeds, skin and barks possess glycosids, carotenoids and phenolic compounds. All parts of the plant have been used for different purposes: hepatoprotection, antioxidant, anti-inflammatory, antispasmodic, anti-cancer, antimicrobial, anti-hyperglycemic, analgesic, endothelial progenitor cells, anti-stomachache and anti-diarrhea. P. guajava has many effects on health and that it should be researched more extensively in clinical trials. Furthermore leaves, seeds and peel are treated as wastes by the food processing industry and are discarded, so their use may reduce the disposal of these parts of guava as pollutants.

Comparative Study of Effectiveness of Wound Cleansing Solution in Diabetic Wound Care

“…Guava leaves extract allege to have the ability as an analgesic, anti-inflammation, antimicrobial, because its contains anti-oxidant and phenolic compounds (Ryu, et al (2012); Ojewole (2006); Nair & Chanda (2007); Huiyin & Gow-Chin (2007);Hawrelak (2003); in Barbalho, et al (2012)). Component in guava leaves extract was assumed to speed wound healing, inhibits the growth of grampositive and gram-negative bacteria in diabetic patients.…”

RNA-sequencing based gene expression landscape of guava cv. Allahabad Safeda and comparative analysis to colored cultivars

“…Up-regulation of 4 isomeric transcripts of RML in peel of guava suggests that red guava fruits may serve as a good source for extracting alkaloids like reticulin and laudenin rather than a much-regulated source like poppy. Although the reticulin and laudenin are extracted from poppy for medicinal purposes as an anti-diarrheal, anti-dysenteric, anticough, the use of guava fruit for similar utility have been described before [10,13]. BLAST search of four RML transcripts identified its homologs in eucalyptus, grape and cork oak tree with 74-86% identity.…”

“…Guava possesses large quantities of vitamin C [6], is a rich source of phenolic compounds [10] and carries secondary metabolites with medicinal properties [11,12]. Guava intake induces resistance against infectious agents such as Staphyloccocus, scavenge cancer causing free radicals and helps in the structural protein, collagen synthesis which maintains integrity of blood vessels, skin, organs, and bones [13].…”
