Phytochemical investigation of the aerial parts of Aconitum naviculare, a medicinal plant used in traditional Nepalese medicine, led to the isolation and characterization of two new diterpenoid alkaloids, navirine B (1), and navirine C (2), along with (+) chellespontine (3), kaempferol-7-O-β-D-glucopyranosyl(1→3)α-L-rhamnopyranoside (4), kaempferol-7-O α-Lrhamnopyranoside, 3-O-β-D-glucopyranoside (5), p-coumaric-4-O-β-D-glucopyranoside acid (6), and ferulic-4-O-β-Dglucopyranoside acid (7).

Abstract

Phytochemical investigation of the aerial parts of Aconitum naviculare, a medicinal plant used in traditional Nepalese medicine, led to the isolation and characterization of two new diterpenoid alkaloids, navirine B (1), and navirine C (2), along with (+) chellespontine (3), kaempferol-7-O-β-D-glucopyranosyl(1→3)α-L-rhamnopyranoside (4), kaempferol-7-O α-Lrhamnopyranoside, 3-O-β-D-glucopyranoside (5), p-coumaric-4-O-β-D-glucopyranoside acid (6), and ferulic-4-O-β-Dglucopyranoside acid (7). The structures of the isolated compounds were elucidated on the basis of extensive analyses of 1D and 2D NMR spectra (HMQC, HMBC, COSY, ROESY) and HR-MS data. The antiproliferative activity of alkaloids 1-3 against human tumor cell lines (LoVo and 2008) was also evaluated.
