Most species are cultivated as ornamental plants. In the Philippines, there are at least 109 species of Hoya; 88 of these are endemic to the country. One of the endemic species is &lt;em&gt;Hoya meliflua&lt;/em&gt; often confused with &lt;em&gt;H. diversifolia&lt;/em&gt;, which can also be found in other countries. This study is part of our research on the chemical constituents of Philippine native Hoyas.&lt;strong&gt; Methods:&lt;/strong&gt; The compounds were isolated by silica gel chromatography and identified by NMR spectroscopy. &lt;strong&gt;Results:&lt;/strong&gt; Chemical investigation of the dichloromethane extract from the leaves of&lt;em&gt; Hoya meliflua&lt;/em&gt; afforded squalene and mixtures of β-amyrin (1a), α-amyrin (1b) and lupeol (1c) in about 1:1:0.25 ratio; oleanone (2a), ursenone (2b) and lupenone (2c) in about 1:1:0.3 ratio; β-amyrin cinnamate (3a), α-amyrin cinnamate (3b) and lupenyl cinnamate (3c) in about 0.5:0.3:1 ratio; and β-sitosterol and stigmasterol in about 5:1 ratio. &lt;strong&gt;Conclusion:&lt;/strong&gt; The results of our study indicate that &lt;em&gt;Hoya meliflua&lt;/em&gt; shares similar chemical characteristics with other members of the genus Hoya. The triterpenes and sterols obtained from H. meliflua were also identified from other &lt;em&gt;Hoya&lt;/em&gt; species. It is interesting to note that although most Hoya plants have no known biological activity and medicinal property, the compounds isolated from H. meliflua possess diverse bioactivities.&lt;/p&gt;
