characterization of volatiles in strawberry Guava psidium cattleianum sabine fruit
Journal of Agricultural and Food Chemistry, 2001Co-Authors: Jorge A Pino, Rolando Marbot, Carlos VazquezAbstract:Volatile compounds were isolated from strawberry Guava fruit by simultaneous steam distillation−solvent extraction according to Likens−Nickerson. Compounds were identified by capillary GC-MS and sensorially characterized by sniffing GC. Two hundred and four compounds were identified in the aroma concentrate, of which ethanol, α-pinene, (Z)-3-hexenol, (E)-β-caryophyllene, and hexadecanoic acid were found to be the major constituents. The presence of many aliphatic esters and terpenic compounds is thought to contribute to the unique flavor of the strawberry Guava fruit. Keywords: Volatiles; strawberry Guava; aliphatic esters; terpenic compounds

nutritional and nutraceutical comparison of jamaican psidium cattleianum strawberry Guava and psidium guajava common Guava fruits
Food Chemistry, 2012Co-Authors: Kayanne P Mccookrussell, Muraleedharan G Nair, Petrea C Facey, Camille S BowenforbesAbstract:Abstract Psidium cattleianum (strawberry Guava) is one of many underutilised edible fruits that grow wild in Jamaica, and could potentially be commercially exploited to yield health and economic benefits. In this study, the total phenolics, proximate contents, and antioxidant, anti-inflammatory, and antimicrobial activities of P. cattleianum and P. guajava (common Guava), a well-known species, were compared. Strawberry Guavas were found to be superior to common Guavas in antioxidant and antimicrobial activities, total phenolics and vitamin C content. They also possessed relatively high fibre content (24.9%). The hexane and ethyl acetate extracts of strawberry Guavas showed cyclooxygenase-2 enzyme inhibitory activities of 18.3% and 26.5%, respectively (250 μg/mL), indicating anti-inflammatory activity. The EtOAc and MeOH extracts of P. guajava showed 56.4% (COX-2) and 44.1% (COX-1) inhibitory activity, respectively. Additionally, nine compounds were isolated from strawberry Guava fruits, some of which demonstrated anti-inflammatory activity. These results indicate that strawberry Guavas are beneficial for health.

proximate analysis in vitro organic matter digestibility and energy content of common Guava psidium guajava l and yellow strawberry Guava psidium cattleianum var lucidum tree parts and fruits as potential forage
Journal of Agricultural and Food Chemistry, 2012Co-Authors: Julie Ann Luiz Adrian, Norman Q Arancon, B W Mathews, James R CarpenterAbstract:The nutrient composition of common Guava, Psidium guajava L., and strawberry Guava (waiwi), Psidium cattleianum var. lucidum, tree parts and fruits was determined during three seasons for six locations in Hawaii to assess Guava as a potential feed for cattle. All Guava plant parts were higher (p < 0.001) in crude protein than waiwi, but there were no differences in the fiber and energy densities for bark, shoots, and branches. Guava leaves were higher in fiber and had lower energy densities (p < 0.05) than waiwi. Ripe and breaker stage fruits were lower (p < 0.05) in fiber, similar in protein (CP), and higher (p < 0.05) in energy density than immature fruits. Guava fruits were higher in CP (p < 0.05) and organic matter (p < 0.001) and lower in ash (p < 0.001) than waiwi fruits. The primary nutritional concern with Guava is low in vitro organic matter digestibility as compared to tropical forage grasses; therefore, it is not recommended as a feedstock for livestock.
