en بیوشیمی Biochemistry مقالات اصلی Original Article <div style="text-align: justify;"><strong><em>Background: </em></strong>Orcinol-&beta;-D-glucoside, which is also known as orcinol glucoside, is a major phenolic&nbsp;glucoside compound in the rhizome of the Curculigo orchioides Gaertn. This compound has many&nbsp;medicinal properties such as being antioxidant, immunomodulatory, antiosteoporosis, stress relief,<br> antidepressant, etc.</div> <div style="text-align: justify;"><br> <strong><em>Methods:</em></strong> Determination of reducing sugar content by Bertrand&rsquo;s method, determination of lipid&nbsp;content by Soxhlet method, determination of vitamin C content by iodine titration, determination of&nbsp;enzyme activity catalase by titration with KMnO4. Quantification of Orcinol-&beta;-D-glucoside was&nbsp;conducted by HPLC analysis.<br> <br> <strong><em>Results:</em></strong> The Orcinol-&beta;-D-glucoside of C. orchioides in Thuy Bang mountain was highest. Besides,&nbsp;the content of reducing sugars, vitamin C, enzyme catalase, and lipids of C. orchioides differed&nbsp;significantly among sites. In which, the reducing sugar and vitamin C of C. orchioides in Ngu Binh&nbsp;mountain was highest. Whereas, enzyme catalase was also highest in Thuy Bang mountain. However,&nbsp;the lipid content of C. orchioides was also highest in Huong Tho mountain.<br> <br> <em><strong>Conclusions: </strong></em>The result will contribute to providing the scientific basis for the selection of breeding,&nbsp;planting, development of C. orchioides in Thua Thien Hue province, as well as other provinces in&nbsp;Vietnam and opening new research directions for applications in the future.</div> Antioxidants, Hypoxidaceae, Medicinal Plants, Vietnam 565 572 http://rbmb.net/browse.php?a_code=A-10-788-1&slc_lang=en&sid=1 Pham Thanh phamthanh@hueuni.edu.vn. 100319475328460012413 100319475328460012413 Yes University of Education, Hue university, Hue 530000, Vietnam.
