Multiple wavelengths maximization fusion fingerprint profiling for quality evaluation of compound liquorice tablets and related antioxidant activity analysis

Dragon fruit (Hylocereus polyrhizus) has polyphenols as an antioxidant. It has known that the antioxidant content of dragon fruit peels was more than in the flesh, so it can be used as a source of natural antioxidants to replace synthetic antioxidants. The use of dragon fruit (Hylocereus polyrhizus) peel, especially as topical preparations in the form of body butter, was still rarely done, whereas dragon fruit peel as an antioxidant can be used as an active ingredient of cosmetics. The purpose of this study was to obtain the body butter formula of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel and its physical quality evaluation, to know the antioxidant activity of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel and its body butter. This research was an experimental study with the stages of research consisting of determination of native plants, making ethanol extract of dragon fruit (Hylocereus polyrhizus) peel, ensuring its activity antioxidant, performing body butter formulation procedures, carrying out physical quality evaluation such as organoleptic, homogeneity, pH, spread, protection, and adhesion ability, then antioxidant activity of its body butter. The result of this research showed that the ethanol extract of dragon fruit (Hylocereus polyrhizus) peel has a moderate level of antioxidant (Antioxidant Activity Index / AAI = 0,88). Furthermore, body butter which has contains antioxidant content of ethanol extract of dragon fruit (Hylocereus polyrhizus) peel as much as 0.5% has the best physical quality evaluation during storage and the highest AAI (0,54) among other body butter formulas.

The extraction process from leaves and twigs of gambier (Uncaria gambier Roxb)plant was conducted mechanically by using traditional hydraulic press, conventional screw press, and modified twin-screw press. The leaves and twigs of gambier plant was obtained from traditional farmer in Limapuluh Kota, West Sumatera, Indonesia. The water, ash and catechin contents of the gambier extracts were analyzed based on SNI 01-3391-2000 using spectrophotometry and thermogravimetry method. Antioxidant activity analysis of the extracts was also performed by 1,1-diphenyl-2-picrylhidrazyl (DPPH) method and compared tovitamin C as a standard antioxidant. The analysis results showed that the extracts contain no ash. Meanwhile, the catechin and water contents of the extracts were approximately 50 and 13% thus the extracts were classified as quality gambier 2. Other than that, analysis result of catechin and epicatechin contents of the extracts using HPLC and compared to the reference materials showed that catechins contents of the extracts using traditional hydraulic press, conventionalscrew press, and modified twin-screw press give catechin content in about 94.296-95.030%. However, epicatechin was detected in a trace amount. The antioxidant activity of the extracts were 2.5 times stronger than reference. The IC50 value of 4.37-4.52 µg/mL and was categorized as active antioxidant.

Dipsaci Radix, the dry root of Dipsacusasper Wall. ex Henry, is a commonly used traditional Chinese medicine (TCM). A novel comprehensive method was proposed for quality evaluation of wine-fried Dipsaci Radix by an integrated data including three aspects of information: high performance liquid chromatography (HPLC) fingerprint, asperosaponin VI content and antioxidant activity (AA). Various indicators including fingerprint similarity, asperosaponin VI content and AA were respectively employed for quality assessment of processed Dipsaci Radix samples. Results showed that considerable differences existed in quality of processed samples with different processing conditions according to three indicators. Among the factors affecting quality of wine-fried Dipsaci Radix, heating temperature was the most influential factor based on analysis of variance (ANOVA), and should be cautiously controlled. The three evaluation indicators respectively used for optimization of processing technology suggested different optimal conditions of wine-frying. Therefore, a combined indicator based on three evaluation indicators was used for determination of optimal processing condition. Multivariate statistical methods such as Hierarchical Clustering Analysis (HCA) and Principal Components Analysis (PCA) were both employed to classify the processed samples for quality evaluation. To more comprehensively evaluate the quality of wine-fried Dipsaci Radix, HPLC fingerprint combined with content of asperosaponin VI and AA may be a reasonable and practical approach.
