vanda coerulea/抗氧化剂

A droplet-vitrification cryopreservation protocol has been successfully developed for Aranda Broga Blue orchid hybrid using protocorm-like bodies (PLBs). However, maximum growth regeneration percentage was recorded at 5% only based on previous report. Thus, to improve growth recovery of

BACKGROUND Alzheimer's disease (AD) is a progressively developing neurodegenerative disorder of the brain in the elderly people. Vanda roxburghii Rbr. root has been used traditionally in Bangladesh as tonic to brain and in the treatment of nervous system disorders including AD. Therefore, we aimed

BACKGROUND In our investigations towards the isolation of potentially biologically active constituents from Orchidaceae, we carried out phytochemical and biological analyses of Vanda species. A preliminary biological screening revealed that Vanda coerulea (Griff. ex. Lindl) crude hydro-alcoholic

Throughout the cryopreservation process, plants were exposed to a series of abiotic stresses such as desiccation and osmotic pressure due to highly concentrated vitrification solution. Abiotic stress stimulates the production of reactive oxygen species (ROS) which include hydrogen peroxide,

Orchidaceae is the largest family of flowering plants with over 35,000 species and 850 genera. About 3300 species of orchids are found in Malaysia and the diversity is highest in the Main, Keledang, Bintang and Tahan Ranges. Apart from being prized for their beauty, orchids have long been used by

The essential oil, different extracts, and isolated compounds of Angelica pancicii Vandas (Apiaceae) were investigated for the first time. The GC-FID and GC-MS analyses revealed sesquiterpenoids as the main constituents of A. pancicii essential oil of aerial parts with bornyl acetate (8.08%),

BACKGROUND The genus Vanda (Family: Orchidaceae) comprises about 73 species mainly distributed in Southeast Asia. Plants belonging to this genus are being used in the traditional medicine systems in Asian countries specially in India, Nepal, China and Bangladesh. OBJECTIVE The aim of this work was
