Phytochemical contents and antioxidant capacities of different parts of two sugarcane (Saccharum officinarum L.) cultivars

Quantitative assessment of bioactive compounds and the antioxidant activity of 15 jujube cultivars

“…The highest content of total triterpenes was observed in ShLZ, and the lowest was observed in XFYZ. A similar level of total triterpenes was also reported in different parts of sugarcane (Feng et al, 2014).…”

“…Korekar et al reported similar results (Korekar, Dolkar, Singh, Srivastava, & Stobdan, 2014). A negative correlation between the total triterpenes content and the ABTSÁ-scavenging activity (R 2 = À0.374, p < 0.05) was observed in the paper and also by other studies (Feng et al, 2014). The explanation behind this result is still unclear, as triterpenes have been demonstrated to have antioxidant capacity (Lin et al, 2012;Liu et al, 2010).…”

“…The total triterpenes content was measured using the vanillin-perchloric acid assay method (Feng, Luo, Zhang, Zhong, & Lu, 2014), with some modifications. Briefly, 0.5 mL of each of the extracts or the standard ursolic acid solution (0.2-1.6 mL of 0.1 mg/mL) was lyophilized and mixed with 0.2 mL of vanillinacetic acid solution (5:95, w/v) and 1.0 mL of perchloric acid.…”

“…Triterpenes have attracted particular attention due to their structural similarity with cholesterol and capability of inhibiting its intestinal absorption, resulting in reducing the levels of total plasma cholesterol and low-density lipoprotein levels (Feng et al, 2014). However, comprehensive data on the content of various jujube samples is still limited.…”

Antioxidant and antimicrobial activity of a mangrove plant Avicennia marina (Forsk.)

“…Studies of different researchers revealed that there was a direct correlation between TPC and antioxidant activity [24] or TFC and antioxidant activity of plant extracts [25]. In the present study, the maximum TPC was in polar solvent extracts as also reported by Ammar et al [26] and Chanda et al [27] and the maximum TFC was in ethyl acetate extracts.…”
