A new phenylpropanoid glycoside from Leucas indica Linn.
A new phenylpropanoid glycoside, alpha-L-rhamnopyranosyl-(1 --> 3)-O-alpha-L-rhamnopyranosyl-(1 --> 6)-1-O-caffeoyl-beta-D-glucopyranoside (1) along with two known phenylethanoid glycosides (2-3) has been isolated from the aerial parts of Leucas indica Linn. Their structures were deduced from the spectroscopic studies and compared with the literature values.
