Three new decenynol glucosides were isolated from the aerial parts of . Their structures were determined to be 6,8-decadien-4-yn-ol 1--β-d-glucopyranoside, 6,8-decadien-4-yn-ol 1--β-d-glucopyranoside, and 6-decen-4-yn-ol 1--β-d-glucopyranoside based on extensive spectroscopic (NMR and MS) analysis.

Ten compounds, including a new guaiane-type sesquiterpene lactone, were isolated from the aerial parts of . The structure of the new compound was determined to be 5-hydroxyguaia-3(4),11(13),10(14)-trien-6α,12-olide, named scoparanolide. Six known sesquiterpene lactones [estafiatone, 3β,4α-dihydroxyguaia-11(13),10(14)-dien-6α,12-olide, estafiatin, preeupatundin, 3β-hydroxycostunolide, and ludovicin B] and three known coumarin derivatives (scopoletin, scoparone, and isofraxidin) were identified by nuclear magnetic resonance and electrospray ionization mass spectroscopy.

We investigated the antihypertensive effects of Artemisia scoparia (AS) in spontaneously hypertensive rats (SHR). The rats were fed diets containing 2% (w/w) hot water extracts of AS aerial parts for 6 weeks. The AS group had significantly lower systolic and diastolic blood pressure levels than the control group.
