“…In fall/winter samples from greenhouse growth (samples GFe-GWl), the total amount of organic acids decreases throughout the plant’s cycle, but those from the spring harvest (samples GSe-GSl) showed a slight increase in the middle stages of development (Table and Figure ). The decrease observed in total organic acids contents can also be noticed in most fruit during ripening, as a consequence of its use as respiratory substrates and as carbon skeletons for the synthesis of new compounds .…”

Targeted metabolite analysis of aqueous extract of Rumex induratus leaves, in terms of phenolic compounds and organic acids, and the study of its antioxidant activity against the DPPH(*) radical, a reactive oxygen species, hypochlorous acid, and a reactive nitrogen species, nitric oxide ((*)NO), were performed. The samples were collected in several locations, spontaneously occurring or from greenhouse culture, at different stages of development and seasons. The phenolic composition was achieved by high-performance liquid chromatography (HPLC)-diode array detection, and four hydroxycinnamic acid derivatives and 10 flavonoid glycosides (C- and O-heterosides) were determined. Organic acids composition was established by HPLC-UV, revealing five compounds. The total amount of phenolic compounds and organic acids were affected by growing conditions and developmental phase. The aqueous extract exhibited a dose-related activity against all tested reactive species.

“…While partial purification of /3-Gal from tomato (Pressey, 1983) and muskmelon fruit (Ranwala et al, 1992) has been achieved, purification to near homogeneity has been achieved only recently in apple (Dick et al, 1990), kiwi fruit (Ross et al, 1993), and avocado (De Veau et al, 1993). These fruits are all climacteric (Kays, 1991).…”

“…All fruits in which /3-Gal has been studied exhibit climacteric ripening behavior (Kays, 1991). The apparent absence of cell wall hydrolase activity in nonclimacteric fruits has led to the hypothesis that these fruits soften nonenzymatically (Huber, 1983).…”
