Glycosidically Bound Flavor Compounds of Cape Gooseberry (Physalis peruviana L.)

Abstract

The bound volatile fraction of cape gooseberry (Physalis peruviana L.) fruit harvested in Colombia has been examined by HRGC and HRGC-MS after enzymatic hydrolysis using a nonselective pectinase (Rohapect D5L). Forty bound volatiles could be identified, with 21 of them being reported for the first time in cape gooseberry. After preparative isolation of the glycosidic precursors on XAD-2 resin, purification by multilayer coil countercurrent chromatography and HPLC of the peracetylated glycosides were carried out. Structure elucidation by NMR, ESI-MS/MS, and optical rotation enabled the identification of (1S,2S)-1-phenylpropane-1,2-diol 2-O-beta-D-glucopyranoside (1) and p-menth-4(8)-ene-1,2-diol 1-O-alpha-L-arabinopyranosyl-(1-6)-beta-D-glucopyranoside (2). Both glycosides have been identified for the first time in nature. They could be considered as immediate precursors of 1-phenylpropane-1,2-diol and p-menth-4(8)-ene-1,2-diol, typical volatiles found in the fruit of cape gooseberry.

Physalis peruviana Linnaeus, the multiple properties of a highly functional fruit: A review

“…According to Mayorga, Knapp, Winterhalter, and Duque (2001) the fruit of P. peruviana L. has been used as a source of minerals, especially Iron and Potassium. Potassium, like Sodium, plays an important role in the physiological functions of animals and is abundantly distributed in the human diet (Szefer et al, 2007).…”

Obesity and Clinical Riskiness Relationship: Therapeutic Management by Dietary Antioxidant Supplementation—a Review

“…The extracts from different parts of the plant show antihepatotoxic [103] and antiinflammatory [104] activity as well as antiproliferative effects on hepatoma cells [105]. The edible fruits are bearing a complex volatile profile [106] and containing high levels of vitamins A, B, C, β-carotene, phosphorus, and iron [107]. The juice is rich in fat-soluble bioactive compounds (tocopherols and phytosterols) and could be a novel source of functional drinks [108].…”

Influence of Cape gooseberry (Physalis peruviana L.) addition on the chemical and sensory characteristics and mineral concentrations of ice cream

“…It is indigenous to South America but was cultivated in South Africa in the region of the Cape of Good Hope during the 19th century, imparting the common name, "Cape gooseberry" (Wikipedia, 2011). The Cape gooseberry (CG) is an herbaceous, semi-shrub, perennial in subtropical zones and it can grow until it reaches 0.6-0.9 m (Mayorga, Knapp, Winterhalter, & Duque, 2001). Although growing of CG extends all over the South American Andes, it has been found for two decades in markets of many countries (National Research Council (NRC), 1989).…”
