However, its effect and mechanism in gastric cancer and liver cancer are unclear. Moreover, there is no RA report yet in the chemical constituents of Rubi Fructus (RF) . In this study, RA was isolated from RF for the first time, and the effect and mechanism of RA on gastric and liver cancers were evaluated using SGC-7901 and HepG2 cells models. The cells were treated with different concentrations ofRA (50, 75, and 100 μg/mL) for 48 h, and the effect of RA on cell proliferation was evaluated by the CCK-8 assay. The effect of RA on cell morphology and mobility was observed by inverted fluorescence microscopy, cell apoptosis and cell cycle were determined by flow cytometry, and the expression of apoptosis-related proteins cytochrome C, cleaved caspase-3, Bax, and Bcl-2 was detected by western blotting. The results revealed that, with an increase in the RA concentration, the cell viability, mobility, and Bcl-2 expression decreased, while the apoptosis rate, Bax, cytochrome C, and cleaved caspase-3 expression increased, and SGC-7901 and HepG2 cells could be induced to arrest their cell cycle in the G0/G1 and S phases, respectively. These results together indicate that RA can induce apoptosis of SGC-7901 and HepG2 cells through the mitochondrial pathway. Thus, this study supplements the material basis of the anti-tumor activity of RF and provides an insight into the potential mechanism of RA-inducing apoptosis of gastric cancer SGC-7901 cells and liver cancer HepG2 cells, thereby facilitating further developmental studies on and the utilization of the anti-tumor activity of RF.  \nKeywords Rubi Fructus · Rosmarinic acid · Apoptosis · Mitochondria apoptosis pathway · Anti-tumor  \nIntroduction  \nRosmarinic acid (RA) is a water-soluble natural phenolic acid widely present across 160 species of herbal plants (Guan et al. 2022), originally isolated and named after rosemary (Rosmarinus officinalis, Lamiaceae) .

For liver cancer and gastric cancer, RA led to decrease cell viability and morphological changes in HepG2 cells (Renzulli et al. 2004) as well as a decrease in the survival of SGC-7901 cells (Li et al. 2013) . However, these studies only demonstrated RA’s anti-tumor effect on gastric and liver cancers, with no establishment of the specific underlying mechanisms. Therefore, we aimed to explore the mechanism RA exerted anti-tumor effect on gastric and liver cancers.  \nRubus chingii Hu. , belonging to the family Rosaceae, whose fruits are known as Rubi Fructus (RF), is widely planted for its significant nutritional and medicinal values.
