Abstract

Forage plants are one of the main aspects in the conservation management of the Sumatran elephant. Anatomical studies of elephant food plants can provide reference data needed in identifying the diversity of elephant food plants, especially in the studies with faecal samples. This study aims to provide anatomical data of Sumatran elephant feed plants. The observed samples consisted of leaf samples from 24 species and stem samples from four species. Samples were prepared for microscopic paradermal section using the wholemount method. The results showed that rectangular epidermal cell shapes were found in samples of Poaceae leaves, Cyperaceae leaves and stems, and Arecaceae leaves. Stomata with dumbbell-shaped guard cells were only found in Poaceae leaf samples and Cyperaceae leaf and stem samples. The presence of silica cells and cork cells distinguished the Poaceae samples from Cyperaceae. Other leaf samples had qualitative anatomical characteristics that varied based on anticlinal walls of epidermal cells, type of stomata, and trichomes. Quantitative characterization of epidermal cell size; stomatal size, density, and index; and trichome density are used to complete the species description and distinguish species that have the same qualitative characteristics. Keywords: epidermis, paradermal leaf section, stomata, trichome, wholemount method

Abstract

Hyptis capitata Jacq. (common name: Knobweed or False Ironwort) belongs to Lamiaceae family and is among known traditional medicine. The Anak Dalam Tribe of Jambi Province uses the leaves of H. capitata to cure external and internal wounds. This study was aimed at identifying and analyzing secretory structure, histochemistry and phytochemical content of H. capitata leaves.  The results showed that H. capitata leaves have secretory structures in the form of peltate, capitate and uniseriate glandular trichomes on the upper and lower leaf surfaces, with idioblast cells scattered throughout the leaf mesophyll. Histochemical tests indicated that the peltate trichomes have four head cells, containing alkaloids and terpenoids. This study classified capitate trichomes into two types: 1. type I has one stalk cell and two head cells, all containing  alkaloids, terpenoids and lipophilic compounds; 2. type II has long stalk cells consisting of seven to ten cells with one head cell, all containing alkaloids and terpenoids. Uniseriate glandular trichomes of H. capitata leaves consist of four to eight cells containing alkaloids and terpenoids. The idioblast cells are round-shaped and contain lipophilic compounds. GC-MS analysis showed that H. capitata leaves  contain terpenoid compounds assumed to serve as anti-infective agents, including l-limonene, eugenol, farnesol isomers A, d-nerolidol, hexahydrofarnesol and neophytadiene.
