The genus Sida with about 90 species is distributed widely in the temperate zone in the whole world. Sida szechuensis, which is a perennial, half-shrub found throughout the highland of southwestern China and abundant in resources, i s one of species of Malvaceae. It is used in Chinese traditional medicine for ul cers, furuncle, dysentery and blood stasis through ethnopharmacological explorat ion. Modern pharmacological experiments show that it can inhibit platelet aggreg ation (Xiao et al, 1997). However, to our knowledge, the study on the chemic al constituents of this plant has not been reported as yet. In the course of our search for bioactive natural products, three phytoecdysones, (-ecdysone(1), (-e cdysone (2) and polypodine B (3) were isolated and identified from this herb.
