title: [Studies on the chemical constituents of Urtica dioica L. grown in Tibet Autonomous Region].
abstract: Studies on the whole herb of Urtica dioica L. grown in Nyingchi area, China's Tibet Autonomous Region, resulted in the isolated of nine compounds: beta-sitosterol, trans-ferulic acid, dotriacotane, erucic acid, ursolic acid, scopoletin, rutin, quercetin and p-hydroxylbenzalcohol. Dotriacotane, erucic acid, scopoletin, rutin and p-hydroxylbenzalcohol were obtained from Urtica L. for the first time. Their structures were confirmed by modem spectral analysis (NMR, MS, etc).
