The flavonoids 5,3’,4’-trihydroxy-7-methoxyflavone, 5,3’-dihydroxy-7-4’-dimethoxyflavone, 5,4’-dihydroxy-7-methoxyflavone and steroids mixture (β-sitosterol and stigmasterol) were isolated from the dried aerials parts of Piper carniconnectivumC.DC. Their structures were established by spectroscopic analyses (UV, IV and ¹H, 13C NMR, including 1D and 2D NMR).
Piper carniconnectivum; 5,3’,4’-trihydroxy-7-methoxyflavone; 5,3’-dihydroxy-7-4’-dimethoxyflavone; 5,4’-dihydroxy-7-methoxyflavone; β-sitosterol; stigmasterol
