Optimization of spray drying process parameters of Piper betle L. (Sirih) leaves extract coated with maltodextrin
Piper betle L., more commonly known as betel or local name of Sirih, belongs to the family Piperaceae. Previous researches had shown that the leaves of P. betle possess tremendous beneficial effects including antimicrobial, antioxidant, anti-diabetic, wound healing and gastro-protective properties. This is due to the present of the two bioactive component; propenylphenols; which is the Hydroxyc...
متن کاملTwo new sphingolipids from the leaves of Piper betle L.
Two new sphingolipids, pipercerebrosides A (1) and B (2), were isolated from the leaves of Piper betle L. Their structures, including absolute configurations, were determined by spectroscopic analysis and chemical degradation. These two compounds did not show significant cytotoxic activity against the cancer cell lines K562 and HL-60 in a MTT assay.
متن کاملVacuum Drying Characteristics of Salicornia herbacea L
Vacuum drying of Salicornia herbacea L. was performed at different drying temperatures (50, 60, 70, and 80°C) to evaluate the drying characteristics and the effect of drying temperatures on the quality of Salicornia. As the drying temperature increased, the drying time decreased significantly (P< 0.05). The drying rate decreased with decrease in moisture content and increase in drying time. On ...
متن کاملRole of Petiole in Protein Metabolism of Senescing Betel (Piper betle L.) Leaves.
Effects of depetiolation on protein metabolism during senescence of detached betel (Piper betle L.) leaves have been studied. In normal petiolated leaves, the level of chlorophyll and proteins and extent of protein synthesis declined, while the protease activity registered manifold increase with the advancement of senescence. All of these changes were delayed by depetiolation/de-midribbing trea...
متن کاملScanning Electron Microscopic study of Piper betle L. leaves extract effect against Streptococcus mutans ATCC 25175
INTRODUCTION Previous studies have shown that Piper betle L. leaves extract inhibits the adherence of Streptococcus mutans to glass surface, suggesting its potential role in controlling dental plaque development. OBJECTIVES In this study, the effect of the Piper betle L. extract towards S. mutans (with/without sucrose) using scanning electron microscopy (SEM) and on partially purified cell-as...
