“…The GC-MS analysis showed high amount of phenol in extracts which indicated that the extract was high in oxidative properties. Such high concentration of phenols in microalgae extracts with anti-oxidative properties have been reported in multiple studies [ 70 – 72 ]. Other major acids present in the extract are glycolic acid, butenoic acid, benzoic acid, glutaric acid, hexenedioic acid, octadecanoic acid.…”

The current study is focused on the lipid extract of microalgae; Pectinodesmus strain PHM3 and its general analysis in terms of chemical contents. Combinations of both chemical and mechanistic approaches were applied to obtain the maximum yield of lipids which was recorded to be 23% per gram through continuous agitation using Folch solution. The extraction methods used in this study included: Bligh and Dyers method, Continuous agitation method, Extraction using Soxhlet and Acid base extraction method. Lipid quantification of ethanol and Folch solution lipid extract was performed through gravimetric methods and qualification was done through Fourier Transmission Infrared Spectroscopy (FTIR) and Gas Chromatographymass spectrometry (GC-MS). Phytochemical analysis identified other compounds in ethanol extract and the results confirmed the presence of steroids, coumarins, tannins, phenols and carbohydrates. Transesterification of lipids showed 7% per gram dry weight yield of Pectinodesmus PHM3. GC-MS studies of extracted biodiesel suggested that 72% of biofuels was in the form of dipropyl ether, ethyl butyl ethers, methyl butyl ether and propyl butyl ether. Lipid processing of acid-base extract showed that oily nature of lipid shifted to a more precipitated form which is a common observation when mixture of lipids is converted to phosphatides.

“…The radical-scavenging activity of the cookie samples was studied using the stable DPPH radical, as described by Blois (1958) [23], with some modifications [24]. Different concentrations (100 to 300 µg/mL) of samples and 2 mL of DPPH (100 µM) were added, made up to 3 mL with methanol, and the reaction mixture was incubated in the dark for 45 min at room temperature.…”

Background: Noni, also known as Morinda citrifolia L., is a perennial herb with Southeast Asian origins that has been used medicinally for over 2000 years. Noni drew the interest of researchers from the pharmaceutical and food industries due to its adaptability and utilization of the plant's structures for various food applications. The essential industrial products of this plant are beverages, leaf powders, oil from seeds, and powders from dried fruits. Objective: This study aimed to incorporate noni fruit powder with different concentrations to extend the cookie’s shelf life and nutritional properties. Methods: In the formulation of the cookies, noni fruit powder was fortified with four different concentrations (5% - NFPFC5, 10% -NFPFC10, 15% - NFPFC15, and 20% - NFPFC20) with wheat flour. The physical properties, antioxidant activity, and sensory characteristics of cookies fortified with noni fruit powder were studied. Results: There was no significant change in the physical properties of fortified cookies with noni fruit powder. The antioxidant properties were enhanced with the higher concentrations of fruit noni powder fortified with cookies. Sensory panelists preferred cookies with 5% noni (NFPFC5) concerning organoleptic characteristics. Conclusion: The present study is to understand the herb's value by recommending the nutritional qualities and sensory evaluation of noni fruit powder cookies. Future studies on the use of noni fruit powder in different food industries with its applications in terms of safety and quality are necessary.Keywords: Noni powder, antioxidant, Morinda citrifolia, sensory acceptance, cookies.

Volatile oils from several Bupleuri radix (BR) are reported as potential sources of drugs. To provide evidence for the application of BR, the volatile oils from 19 batches of different species and habitats of BR including Bupleurum chinese DC. (BCD), Bupleurum scorzonerifolium Willd. (BSW), Bupleurum bicaule Helm (BBH), Bupleurum marginatum var. stenophyllum (Wolff) Shan et Y.Li (BMS), Bupleurum marginatum Wall.ex DC. (BMW) and Bupleurum falcatum L. (BFL) were investigated. The composition of BR volatile oils was determined by GC/MS. Samples were clustered by hierarchical cluster analysis (HCA). Fever was induced by Lipopolysaccharide (LPS), and antipyretic activities of BR volatile oils were evaluated with Chaihu injection (CI) as the positive control. The yields of volatile oils were among 360–5320 ppm. A total of 229 components were identified by GC/MS. Samples could be divided into 4 clusters by HCA. 4 representative samples, one for each cluster, were selected to further compare their antipyretic activities. For the highest content of volatile oil (5320 ppm) and the best activity, BSW has great potential for utilization.
