The results suggested that quinones in multi-origin Rubia examples were different, but 10 quinones been around in all examples. R. cordifolia, which is an original official medicinal material in Chinese Pharmacopeia, included the essential quantity of quinones among all of the Rubia types. R. podantha and R. sylvatica had the next greatest number of quinones, implying why these species could possibly be utilized as choices for R. cordifolia. Chemometric approaches were applied to judge the chemical relationship between the Rubia examples in line with the constituent quinones. In this study, a UPLC-QqQ-MS/MS method when you look at the MRM mode has been created for the analysis of Rubia species-derived quinones, which not only plays a role in quality control and discrimination of Rubia species, but also indicates the potential of these types in medical and commercial applications.This paper aimed to investigate the postmortem aging means of beef M. semitendinosus (ST, just slaughtered muscle tissue) utilizing ultrasound-assisted l-histidine treatment. The treatments with different concentrations of l-histidine solutions (0.1%, 0.15%, and 0.2%, w/v) at 4 °C for 60 min were labeled "LH", "MH" and "HH", respectively. Additionally, the corresponding treatments with the above l-histidine solutions for 55 min after ultrasound pretreatment for 5 min were labeled "ULH", "UMH" and "UHH", correspondingly. The outcomes showed that the UMH team had the cheapest Warner-Bratzler shear anxiety. The pH worth of the HH and UHH teams was more than compared to one other teams (HH 6.39 ± 0.02, UHH 6.52 ± 0.03, P less then 0.05). The MH and UMH teams revealed big fiber spacing, ca
