Chain Chemical Constituents of Malus rockii#br#

Abstract

Abstract: Objective: To study the chemical constituents of the dried twigs and leaves of Malus rockii. Methods: Silica gel, MCI, and
Sephadex LH-20 column chromatography were used to isolate and purify the chemical constituents from the 95% ethanol extract of the
dried twigs and leaves of M. rockii. The isolated compounds were identified based on physicochemical properties and modern
spectroscopic analysis techniques. Results: Seven monomeric compounds were isolated from the 95% ethanol extract of the dried twigs
and leaves of M. rockii and were identified as trans-phytol （1）, phytenal （2）, phytyl palmitate （3）, 1-hexadecanoyl propan-2, 3-diol
（4）, methyl 9, 12, 13-trihydroxyoctadeca-10E, 15Z-dienoate （5）, α-linolenic acid （6）, and octadecanol （7）. Conclusion: All the
compounds were isolated from M. rockii for the first time, and compounds 1-6 were isolated from the Malus genus for the first time.

Key words: Malus rockii, chemical constituents, chain diterpenoids, fatty acids
