Article Abstract
Chemotherapeutic drugs and radiotherapy are fundamental treatments to combat cancer, but, often, the doses in these treatments are restricted by their non-selective toxicities, which affect healthy tissues surrounding tumors. On the other hand, drug resistance is recognized as the main cause of chemotherapeutic treatment failure. Rosmarinic acid (RA) is a polyphenol of the phenylpropanoid family that is widely distributed in plants and vegetables, including medicinal aromatic herbs, consumption of which has demonstrated beneficial activities as antioxidants and anti-inflammatories and reduced the risks of cancers. Recently, several studies have shown that RA is able to reverse cancer resistance to first-line chemotherapeutics, as well as play a protective role against toxicity induced by chemotherapy and radiotherapy, mainly due to its scavenger capacity. This review compiles information from 56 articles from Google Scholar, PubMed, and ClinicalTrials.gov aimed at addressing the role of RA as a complementary therapy in cancer treatment.
The current study aims to prepare a green extract using a new method in addition to conventional extraction methods including; methanolic and ultrasonic extraction of , to compare their phenolic composition utilizing high-performance liquid chromatograph equipped with a diode array detector (HPLC-DAD), anti-bacterial, anti-oxidant, and enzyme inhibition activities. The results of HPLC-DAD analysis showed that Rosmarinic acid was found the highest amount in the methanolic extract followed by ultrasonic and green extracts as 169.7 ± 0.
The present study evaluated the antioxidant and anti-inflammatory properties of (CA) fruit extract against bisphenol A (BPA)-induced ovarian injury in female Wistar rats. The antioxidant activity was estimated by the total antioxidant capacity (TAC) and superoxide radical (NBT) content. For the in vivo analyses, 24 animals were divided into the following 4 groups: the control group; the BPA group (50 mg/kg BW BPA for 30 days); the BPA + CA group (50 mg/kg BW BPA and 50 mg/kg BW CA); and the CA group (50 mg/kg BW CA).
Many plants are reported to enhance cognition in amnesic-animal models. The metabolite profile of fruit methanolic extract (CDFME) was characterized by LC-QTOF-MS/MS, and its total phenolics content (TPC) and total flavonoids content (TFC) were determined. In parallel, its cognitive-enhancing effect on scopolamine (SCOP)-induced AD in rats was evaluated.
Cyclophosphamide (CP) is widely used in chemotherapy to treat various types of cancer. However, it is toxic to the liver and other organs. Rosmarinic acid (RA) possesses anti-inflammatory, antioxidant, and cytoprotective properties.

This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Xuebijing Injection by establishing high-performance liquid chromatography(HPLC) fingerprints of 25 batches of Xuebijing Injection and determining the contents of 9 major components, as well as conducting network pharmacology research. Thirty common peaks were identified by fingerprints of 25 batches of Xuebijing Injection samples, and 12 chromatographic peaks were determined, with similarity ranging from 0.970 to 0.
