Abstract

Moringa oleifera Lamk. is a good source of natural antioxidants because it contains various types of antioxidant compounds such as ascorbic acid, flavonoids, phenolics, and carotenoids. Those antioxidant components forming complex structure have transitional metal as central compound, which have free radical scavenging activity. This study aims to determine the active compounds that act as scavenger in leaves and seeds of M. oleifera. The possible compound found in leaves-seeds is elaborated by in silico analysis, using Dr. Duke's Phytochemical and Ethnobotanical Databases, by mean Pass online, and HitPick software. The results of in silico analysis 3 compounds identified in the leaves that had a high antioxidant role, namely beta-carotene, kaempferol, quercetin, and 2 compounds in seeds that had a high antioxidant role, namely alpha-tocopherol, beta-carotene. The results of this study indicate that the antioxidant activity of the 3 treatments had differences effectiveness of antioxidants. All of these antioxidants has ability to bind transitional metal to form free radical scavenger.

Abstract

Orchids are one of the most favorite cut flowers, flowering potted plants, and have developed into a highly profitable industry. The development of acclimatization method is a necessity for the high survival rate of plantlets. The aim of this study was to investigate the effect of low indole-3-butyric acid (IBA) concentration on faster root formation of Dendrobium hybrid planted on coco- husk and charcoal in a short time. Plantlets derived from the seed culture of Dendrodium milla nayla x Dendrobium striaenopsis were harvested and pre-acclimated, planted on charcoal or coco-husk, and regularly sprayed with 0.25, 0.50, 0.75, and 1.0 mg/L IBA twice a week for one month. The results showed that IBA at 0.50 mg/L provided the most appropriate concentration for immediate root induction and growth of Dendrobium hybrid planted on coco-husk. Root number (1.75) and root length (0.28 cm) showed the highest and the most important indicator of adventitious root induction
