Efficacy of protein rich pearl powder on antioxidant status in a randomized placebo-controlled trial
Pearl is one of the well-known traditional Chinese medicine (TCM) prescribed for treating various skin and bone related disorders due to its abundant proteins and mineral contents. The present investigation focused on antioxidation and life span prolonging effects from different extracts of pearl po...

description | Pearl is one of the well-known traditional Chinese medicine (TCM) prescribed for treating various skin and bone related disorders due to its abundant proteins and mineral contents. The present investigation focused on antioxidation and life span prolonging effects from different extracts of pearl powder. During in vitro studies, various oxidative indices were evaluated, along with lifespan-prolonging effect were checked using wild-type Caenorhabditis elegans. For the clinical trial, 20 healthy middle-aged subjects were recruited and separated into 2 groups as experimental and placebo group, who received 3 g of pearl powder/d (n = 10) and 3 g of placebo/d (n = 10) for 8 weeks, respectively. During the initial, 2nd, 4th, 6th, 8th and 10th weeks the blood samples were collected for biochemical analysis. The protein extract of pearl powder recorded maximum (p < 0.05) antioxidant activity (20–68%) as well as efficiently prolonged the life span of C. elegans by 18.87%. Pearl powder supplemented subjects showed a substantial increase (p < 0.05) in total antioxidant capacity from 0.45 to 0.69 mM, total thiols from 0.23 to 0.29 mM, Glutathione content from 5.89 to 9.19 μM, enzymic antioxidant activity (SOD-1248 to 1308; Gpx-30 to 32; GR-2.4 to 2.9) as well as considerably suppressed the lipid peroxidation products from 4.95 to 3.27 μM. The outcome of both in-vitro and in-vivo antioxidant activity inferred that protein extract of pearl powder was a potent antioxidant and thereby prolonged the lifespan of C. elegans. Hence, pearl powder could be recommended for treating various age-related degenerative disorders. |
