“…However, the very small particles are more prone to float in the extraction solvent and therefore, the contact with the solvent is limited [27]. Therefore, the GA yield for particle <125 ȝm is lesser than that of >125 -250 ȝm.…”

Abstract. This paper presents the effect of particle size and solvent type on the gallic acid (GA) extraction yield obtained from Labisia pumila. The GA extraction from a grinded dried plant material (66.66 μm to 1055.18 μm) was performed using the sonicator probe. The GA quantification and identification was performed using a liquid chromatography with photodiode array detector. Exact match between the spectra obtained from the plant extract and external standard was found indicating a presence of GA. In addition, matching of residence time between the standard and plant extract are also observed. It was found that particle size significantly affects the yield of GA and the highest yield (0.150 mg GA/g DW) was obtained using the particle size around 125 μm. Solvent type does also plays an important role in GA extraction. The result shows that extraction using water as solvent yielded about 29% higher GA content (0.126 mg GA/g DW) than that of 10% ethanol (0.098 mg GA/g DW). The findings in this work may serve as a useful guide to select the particle size and solvent used to maximise GA extraction from L. pumila.

“…On the other hand, according to the authors, when there is less plant growth, due to lower water availability, the concentration of these nutrients in plant tissue may increase, which may have occurred in the case of fiber, in which the water stress increased the content in grains. Paiva et al (2015) analyzed the profile and levels of bioactive amines in 22 of these same 100 sorghum genotypes and observed that water stress caused accumulation of spermidine in the grains and affected the levels of other amines.…”

“…However, recently, there is considerable interest in sorghum for food because of its phytochemical content, nutritional potential and the possibility of use in gluten-free products (Awika and Rooney, 2004;Paiva et al, 2015;Taylor et al, 2014). Embrapa (Brazilian Agricultural Research Corporation) Maize & Sorghum has a large collection of sorghum accessions (more than 7000) that have not been characterized for these food quality characteristics; consequently, there is great potential to be explored for use in human nutrition.…”

“…Owing to its wide range of adaptability and ease of growth, sorghum is largely produced in Asian and African countries, and is a good alternative source of animal feed and human food [ 3 , 12 ]. Moreover, it contains various nutrients and bioactive compounds [ 13 , 14 ], such as phenolic acids (ferulic, tannic, and p -coumaric acids), flavonoids (luteolin, apigenin, catechin gallate, and epigallocatechin [ 15 , 16 ]), tannins [ 3 , 17 ], and lipids [ 18 ]. The presence of these valuable bioactive compounds may be responsible for its high LDL inhibition potential [ 19 , 20 ], antioxidant and antibacterial effects [ 21 ], anticancer activity that prevents gastrointestinal tract cancer [ 22 , 23 , 24 , 25 ], and role in preventing obesity, diabetes, and cardiovascular diseases, in addition to reducing hypertension [ 5 ].…”

Sorghum is a major cereal food worldwide, and is considered a potential source of minerals and bioactive compounds. Its wide adaptive range may cause variations in its agronomic traits, antioxidant properties, and phytochemical content. This extensive study investigated variations in seed characteristics, antioxidant properties, and total phenolic (TPC) and flavonoid contents (TFC) of sorghum collected from different ecological regions of 15 countries. The antioxidant potential of the seed extracts of various sorghum accessions was determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azinobis 3-ethylbenzothiazoline-6-sulfonate (ABTS) radical scavenging assays. Significant variations in TPC were observed among the sorghum accessions. All 78 sorghum accessions used in this study exhibited significant variations in TFC, with the lowest and highest amount observed in accessions C465 and J542, respectively. DPPH scavenging potential of the seed extracts for all the accessions ranged from 11.91 ± 4.83 to 1343.90 ± 81.02 µg mL−1. The ABTS assay results were similar to those of DPPH but showed some differences in the accessions. Pearson’s correlation analysis revealed a wide variation range in the correlation between antioxidant activity and TPC, as well as TFC, among the sorghum accessions. A wide diversity range was also recorded for the seed characteristics (1000-seed weight and seed germination rate). A dendrogram generated from UPGMA clustering, based on seed traits, antioxidant activity, TPC, and TFC was highly dispersed for these accessions. Variations among the accessions may provide useful information regarding the phytoconstituents, antioxidant properties, and phytochemical contents of sorghum and aid in designing breeding programs to obtain sorghum with improved agronomic traits and bioactive properties.
