Quantitative analysis of arbutin and hydroquinone in strawberry tree (Arbutus unedo L., Ericaceae) leaves by gas chromatography-mass spectrometry / Kvantitativna analiza arbutina i hidrokinona u listovima obične planike (Arbutus unedo L., Ericaceae) plinskokromatografskom metodom uz detekciju masenim spektrometrom

Abstract

The phenolic glycoside arbutin and its metabolite with uroantiseptic activity hydroquinone occur naturally in the leaves of various medicinal plants and spices. In this study, an extraction procedure coupled with gas chromatography-mass spectrometry (GC-MS) was developed to determine arbutin and hydroquinone content in strawberry tree (Arbutus unedo L., Ericaceae) leaves. The method showed good linearity (R2>0.9987) in the tested concentration range (0.5-200 μg mL-1), as well as good precision (RSD<5 %), analytical recovery (96.2-98.0 %), and sensitivity (limit of detection=0.009 and 0.004 μg mL-1 for arbutin and hydroquinone, respectively). The results obtained by the validated GC-MS method corresponded well to those obtained by high performance liquid chromatography (HPLC) method. The proposed method was then applied for determining arbutin and hydroquinone content in methanolic leaf extracts. The amount of arbutin in the leaves collected on the island of Koločep (6.82 mg g-1 dry weight) was found to be higher (tpaired=43.57, tc=2.92) in comparison to the amount of arbutin in the leaves collected on the island of Mali Lošinj (2.75 mg g-1 dry weight). Hydroquinone was not detected in any of the samples. The analytical features of the proposed GC-MS method demonstrated that arbutin and hydroquinone could be determined alternatively by gas chromatography. Due to its wide concentration range, the method could also be suitable for arbutin and hydroquinone analysis in leaves of other plant families (Rosaceae, Lamiaceae, etc.).

Extraction and Evaluation of Phytochemicals from Banana Peels (Musa sapientum) and Banana Plants (Musa paradisiaca)

Abstract

Banana plants (Musa paradaisica) and banana peels (Musa sapientum) two of same genus Musa are grown in worldwide and consumed as ripe fruit or used for culinary purpose. All parts of the banana plants have medicinal applications. The aim of the present study was detection of phytochemicals from this two types of samples and find out some viable phytochemicals which might be used as food additives after commercial purification. These two types of samples banana plants and banana peels were collected from local area of sobhanbagh near Daffodil International University. Samples were washed and dried in room temperature and grinded in pestle. Then 25 gm of grinded samples were soaked in 75 ml of 70% methanol, ethanol, acetone and 0.9% NaCl solution for 72 hours. Then all the extracts of banana peels and banana plants were detected by standard protocol. Flavonoids, carbohydrates, reducing sugar, tannins, saponins, anthraquinones, steroids, glycosides, phytosterols, phenols, terpenoids, were detected from those extracts. Negative and positive result of presence of phytochemicals were detected by the observing of color change. Banana peels and banana plant extracts were showed maximum result in ethanolic extracts. The present study showed qualitative analysis of phytochemicals content existence in banana peels and banana plants extracts. The study also discussed the application of some phytochemicals in food industry.
