a rich diversity of wild edible fruit trees. The fruits of these tree species have
been consumed by the tribal people since time immemorial. However, there
is limited information available on the biochemical and antioxidant properties
of the fruits. Therefore, the present investigation was undertaken to study the
physico-chemical and antioxidant properties of the nine most important wild
fruit trees. Among the species, Pyrus pashia had the maximum fruit weight
(37.83 g), while the highest juice (43.72%) and pulp content (84.67%) were noted
in Haematocarpus validus and Myrica esculenta, respectively. Maximum total
soluble solids (18.27%), total sugar (11.27%), moisture content (88.39%), ascorbic
acid content (63.82 mg/100 g), total carotenoids (18.47 mg/100 g), and total
monomeric anthocyanin (354.04 mg/100 g) were recorded in H. validus. Docynia
indica had the highest total phenolic content (19.37 mg GAE/g), while H. validus
recorded the highest total flavonoids and flavanol content. The antioxidant
activities of the different fruits ranged from 0.17 to 0.67 IC50 for DPPH activity and
3.59â13.82 mg AAE/g for FRAP. These fruits had attractive pigmentation of both
pulp and juice and were a good potential source for the extraction of natural
edible color in the food industry. The fruits also possess high market prices;
Prunus nepalensis fetched 141.5 per tree. Therefore, these fruits are
rich sources of antioxidants, pigments and have a high market value for livelihood

ALICE luminosity determination for Pb-Pb collisions at âsNN=5.02 TeV
Luminosity determination within the ALICE experiment is based on the measurement, in van der Meer scans, of the cross sections for visible processes involving one or more detectors (visible cross sections). In 2015 and 2018, the Large Hadron Collider provided Pb-Pb collisions at a centre-of-mass energy per nucleon pair of âs NN= 5.02 TeV. Two visible cross sections, associated with particle detection in the Zero Degree Calorimeter (ZDC) and in the V0 detector, were measured in a van der Meer scan. This article describes the experimental set-up and the analysis procedure, and presents the measurement results. The analysis involves a comprehensive study of beam-related effects and an improved fitting procedure, compared to previous ALICE studies, for the extraction of the visible cross section. The resulting uncertainty of both the ZDC-based and the V0-based luminosity measurement for the full sample is 2.5%. The inelastic cross section for hadronic interactions in Pb-Pb collisions at âs NN= 5.02 TeV, obtained by efficiency correction of the V0-based visible cross section, was measured to be 7.67 ± 0.25 b, in agreement with predictions using the Glauber model
