OBJECTIVE
To study the anti-inflammatory and antibacterial effects of different processed products of Rosa laevigata root and stem.
METHODS
Different processed products were obtained from Rosa laevigata root and stem by frying with vinegar,salt,honey and black bean juice. Their antibacterial effect
Bioassay-guided fractionation of an EtOAc extract of the leaves of Rosa laevigata afforded two new 19-oxo-18,19-seco-ursane-type triterpenes (1 and 3), a new ursane-type nortriterpene (2), a new ursane-type triterpene lactone saponin (4), and two new oleanane-type triterpenoids (5 and 6), together
Bioassay-guided fractionation of a n-BuOH-soluble extract of the leaves of Rosa laevigata led to the isolation of three new 19-oxo-18,19-seco-ur-sane-type triterpenoids, laevigins A-C (1-3), a new oleanane-type triterpenoid saponin, laevigin D (4), a new geranylmethylbenzoate,
One new 3,24-dinor-2,4-seco-ursane triterpene, rosanortriterpene C (1), together with four known compounds including 24-norursane-type nortriterpenes (2-3), 24-noroleanane-type nortriterpene (4), ursane-type triterpene (5), was isolated from the fruits of Rosa laevigata var. leiocapus. The new
Particulate matter 10 (PM10) with a diameter of less than 10 mm causes inflammation and allergic reactions in the airways and lungs, which adversely affects asthmatic patients. In this study, we examined the anti-inflammatory effects of Rosa laevigata (RL), which has been previously
The neuroprotective effect and mechanism of the flavonoid-rich extract (FRE) from Rosa laevigata Michx fruit on cerebral ischemia-reperfusion (I/R) injury were investigated. The contents of flavonoids, saponins and tannin were determined, and ten chemicals including chlorogenic acid,
We previously reported the effects of the total flavonoids (TFs) from Rosa laevigata Michx fruit against carbon tetrachloride-induced liver damage, non-alcoholic fatty liver disease, and liver ischemia-reperfusion injury. However, there have been no papers reporting the role of R. laevigata TFs
