Its fruits are palatable and used in manufacture of jams while other parts of the plant are used in traditional medicine to treat various diseases. The main objective of current study was to screen the presence of and isolate the various phytochemicals applying standard procedures and to evaluate the&lt;em&gt; in vitro&lt;/em&gt; antidiabetic activity using α-amylase inhibitory assay. The total methanol extract of flower (TMEF) of &lt;em&gt;Carissa macrocarpa &lt;/em&gt;was subjected to several chromatographic procedures. Results demonstrated that TMEF of &lt;em&gt;Carissa macrocarpa &lt;/em&gt;is characterized by the content of different constituents such as flavonoids, steroids, saponins, tannins and carbohydrates at different levels. Chromatographic isolation led to the isolation of kaempferol-3-O-robinobioside and caffeic acid, which were confirmed via using &lt;sup&gt;1&lt;/sup&gt;H, &lt;sup&gt;13&lt;/sup&gt;C, DEPT, COSY, HMQC and HMBC NMR spectroscopic analyses. TMEF exhibited α-amylase inhibitory activity with IC&lt;sub&gt;50 &lt;/sub&gt;value of 65.4 μg/ml when compared to that of the acarbose (standard) (IC&lt;sub&gt;50&lt;/sub&gt; = 39.6 μg/ml). In conclusion, current investigation endorses the traditional use of &lt;em&gt;Carissa macrocarpa &lt;/em&gt;as antidiabetic herb. Hence, the studied TMEF of &lt;em&gt;Carissa macrocarp&lt;/em&gt;a may have the potential being nutraceuticals products for pharmaceutical applications as antidiabetic herbal remedy.&lt;/p&gt;

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;
