OBJECTIVE To study the chemical constituents in the stem barks of Pandanus tectorius Soland. METHODS The compounds were isolated by repeated chromatography. Their structures were elucidated by spectroscopic methods. RESULTS Ten compounds were isolated and identified as 1＇-O-benzyl-α-L-rhamnopyranosyl-（1″→6＇）-β-D-glucopyranoside （1）, dihydrodehydrodico- niferyl alcohol （2）, isovitexin（ 3 ）, vitexin （4）, 3,5-di-O-caffeoylquinic acid methyl ester（ 5 ）, 3,5-di-O-caffeoylquinic acid ethyl ester （6）, 3,4-di-O-caffeoylquinic acid methyl ester（7）, （ ＋ ）-lyoniresinol 3a-O-β-glucopyranoside（8）, （ - ）-lyoniresinol 3a-O-β-glucopy- ranoside （9） , and benzyl-β-D-glucopyranoside （10）. CONCLUSION All compounds are isolated from this plant for the first time.
