Abstract

Dryocrassyl formate, sitostanyl formate, and 12α-hydroxyfern-9(11)-ene were isolated from the fresh fronds of Cyathea podophylla. Their structures were elucidated by spectroscopic techniques and synthesis. Ten known triterpenoids, three derivatives of phytol, a stanol, and β-tocopherol were also identified from this fern.
