Abstract
|
|
|
|
Antidepressant miquelianin (quercetin 3-O-glucuronide) was isolated from the leaves of Rubus craetaegifolius (Rosaceae) and identified by physical and spectroscopic data. Miquelianin was quantitatively analyzed in the leaves, mature and premature fruits of Korean wild R. craetagifolius, R. pungens var. oldhami, R. coreanus, and R. parvifolius by HPLC. The contents of miquelianin was highest in the mature fruit of R. crataegifolius (16.29 ± 0.79 mg/g); however, the content of kaempferol 3-O-glucuronide was 33.88 ± 7.68 mg/g. These results suggest that the mature fruit of R. crataegifolius would be beneficial for treating depression or stress as a functional food with its sweet taste.
