Embodiment

[0144] Rhizome samples of Acucus spp. were collected from Cuc Phuong National Park (Nho Quan District, Ninh Binh Province, Vietnam). Its methanol extract exhibited potent inhibitory activity against HIV replication, and IC 50 The value is 0.04 μg / mL. A 4.0 kg dry bark sample of this plant was therefore recollected from a Vietnamese National Park to identify anti-HIV compounds. Thus, two novel (1 and 2) and one known (3) arylnaphthyl lignans were isolated from this plant by bioactivity-guided fractionation studies. In structures 1 and 2, Ac stands for acetyl (-COCH 3 ), and Glu represents β-D-glucopyranosyl.

[0145]

[0146] Another sample (4.0 kg) of the rhizome of Scutellaria baicalensis was taken using MeOH extraction to provide an extract (155 g). Isolation of two novel arylnaphthalenoid lignans, japonicamin, by bioactivity-guided fractionation of MeOH extracts by column chromatography on silica gel and RP-18 reversed-phase silica gel followed by preparative HPLC se...
