Terpene hydrocarbons from Psidium guajava

Phytochemistry, 1978
Abstract An extract of whole guava puree, after TLC and GLC, showed the presence of two monoterpenes and nine sesquiterpenes. β-Caryophyllene comprised 95% of this fraction. Possible significance of these hydrocarbons to natural insect attractants and to guava aroma is noted.

Antidiabetic effects of extracts from Psidium guajava

Journal of Ethnopharmacology, 2005
During a screening of medicinal plants for inhibition of protein tyrosine phosphatase1B (PTP1B), an extract from Psidium guajava (Myrtaceae) leaves exhibited significant inhibitory effect on PTP1B. Thus, its antidiabetic effect on Lepr(db)/Lepr(db) mice was evaluated.

ILLUSTRATED DESCRIPTORS FOR GUAVA (PSIDIUM GUAJAVA)

Acta Horticulturae, 2010
Usually, the easiest assessment of genetic variation is through morphological or phenotypic measures. Also, the problems arising from the identification of a great number of plants in a fruit tree collection as well as those concerned with the protection of varietal names ask for the use of specific descriptors. In consequence, the guidelines published
