Abstract
Coastal plants are recognized to yield secondary metabolites including polyisoprenoid alcohols. Coastal plants have been shown to have biological and phytochemical activities. The present study reports the search for polyisoprenoids composition from flowers and fruits of selected coastal plants,Amorphophallus paeoniifolius, Guettarda speciosa, andJatropha curcas. A two-dimensional thin layer chromatography (2D-TLC) was used to analyse the composition and occurrence of polyisoprenoid alcohols (polyprenols and dolichols) in coastal plants. The distribution of polyprenols and dolichols in the flowers and fruits were detected and classified into one type only, type-II. Type-II, having the presence of both polyprenols and dolichols, was found in all samples investigated: in the flowers and fruits ofA. paeoniifolius, G. spiciosa, andJ. curcas. It is interesting to note that no dominating dolichols over polyprenols (type-I) or predominance polyprenol over dolichols (type-III) detected in this study. The present study, therefore, suggested the diversity of polyisoprenoids in the generative tissues of tropical coastal plants.
Highlights
Indonesia has the most significant mangrove area global, which is 22.6 percent of the worldwide total, with the length of shoreline close to at 95,181 km [1]
The selected coastal plants, namely A. paeoniifolius, G. spiciosa, and J. curcas for searching the long-chain polyisoprenoids was investigated by 2D-TLC [3]
The quantity of PI was highest in G. speciosa flowers (121 mg/g dw) and A. paeoniifolius fruits (12 mg/g dw)
Summary
Indonesia has the most significant mangrove area global, which is 22.6 percent of the worldwide total, with the length of shoreline close to at 95,181 km [1]. Mangrove forests in Bali province primarily widespread in Tanjung Benoa and Forest Park Conservation Area Ngurah Rai, Nusa Lembongan, and National Park Bali Barat [2]. Mangrove plants along with coastal plants are important to yield secondary metabolites including polyisoprenoid alcohols [3-6]. The antioxidant activity of A. paeoniifolius correlated to phenolic content [10], antiseizure activities of G. speciosa [8], and antimetabolic constituents of J. curcas [9]. These studies suggested that these mangrove associates are regarded as medicinal values
