Psidium Guajava
Psidium guajava L, belonging to the Myrtacea family, has been reported to have anti-diarrheal, hepatoprotective, hypoglycemic, lipid lowering, antibacterial and antioxidant activities. It contains important phytoconstituents such as tannins, triterpenes, flavonoid:quercetin, pentacyclic triterpenoid:guajanoic acid, saponins, carotenoids, lectins, leucocyanidin, ellagic acid, amritoside, beta-sitosterol, uvaol, oleanolic acid and ursolic acid. In view of the immense medicinal importance of the plant, this review is an effort to compile all the information reported on its phytochemical and pharmacological activities. The present review is an attempt to generate interest among the masses regarding its immense potential in preventing and treating several common diseases.
Psidium guajava L is a fruit-bearing tree commonly known as guava, which belongs to the family Myrtaceae. The French call it goyave orgoyavier ; the Dutch, guyaba , goeajaaba ; the Surinamese, guave or goejaba ; and the Portuguese, goiaba or goaibeira. Hawaiians call it guava or kuawa . In Guam, it is abas . In Malaya, it is generally known either as guava or jambu batu (Morton, 1987). . Guava grows nearly throughout India up to 1500 m in height and is cultivated commercially in almost all states, the total estimated area being 50,000 hectares. The important guava-growing states in India are Uttar Pradesh, Bihar, Maharashtra, Assam, West Bengal and Andhra Pradesh. Cultivated varieties grow about 10 m in height and produce fruits within 4 years. Wild trees grow up to 20 m high and are well branched. The tree can be easily identified by its distinctive thin, smooth, copper-colored bark that flakes off, showing a greenish layer beneath. Guava trees have spread widely throughout the tropics because they thrive in a variety of soils, propagate easily and bear fruits quickly. The fruits are enjoyed by birds and monkeys, which disperse guava seeds and cause spontaneous dumps of guava saplings to grow
