“…The fruit of E. lacunosus was used by the Dulong people to treat traumatic injury. Studies have shown that the fruit of E. ganitrus could act as opioid receptor antagonists to reduce the secretion of neurotransmitters such as acetylcholine, norepinephrine, and dopamine, showing good analgesic effects ( Katavic et al, 2007 ; Hong et al, 2019 ; Prasannan et al, 2020 ). The Dulong people use the fruit of Vaccinium gaultheriifolium to treat rheumatism.…”

The Dulong, an ethnic group living in the isolated Northwest Yunnan of Southwest China, have directly used a wide of plants to serve their needs and have accumulated rich traditional knowledge about medicinal plants over years. Unfortunately, little has been reported about the medicinal plants used by the Dulong people. Ethnobotanical data were collected through semi-structured interviews, guided field trips, and quantitative analysis. Prior informed consent was obtained before each interview. The surveys allowed for the collection of sociodemographic data and traditional knowledge about medicinal plants and their uses. This study used relative frequency of citation (RFC) to identify the most culturally significant medicinal plants and used informant consensus factor (FIC) to evaluate agreement among informants. A total of 105 medicinal plant species belonging to 69 families were recorded. Amongst these 69 families, Asteraceae (8 species), Polygonaceae, Ranunculaceae, and Rosaceae (4 species each) were the dominant families. The whole plants were the most frequently used part in the preparation of medicines. The most common preparation method was decoction and the most frequent application route was oral administration. Coptis teeta (0.15), Acorus calamus (0.12), Ophiocordyceps sinensis (0.11), Tanacetum tatsienense var. tanacetopsis (0.11), and Paris polyphylla var. yunnanensis (0.08) were shown to be the most useful plants as indicated by their relatively high RFC values. Among the usage types of medicinal plants, the highest FIC values were recorded for the circulatory system (FIC = 0.91), the immune system (FIC = 0.89), and the nervous system (FIC = 0.85). Furthermore, sixty-two medicinal plants utilized by the Dulong for medicinal purposes also have dietary use. Traditional knowledge associated with medicinal plants has been seriously threatened in recent decades. In the future, modern approaches should be used to demystify traditional medicine. However, significant measures need to be taken to protect from loss the important traditional knowledge gained by the Dulong through their experience and inheritance. A collective effort should be made to promote and conserve the important traditional medicinal knowledge and outline a plan for sustainable use of medicinal plants and improve local economic development under the premise of protection.

“…The presence of water‐storage cells only in the stellar region of E. variabilis suggests that this feature can be used to distinguish E. variabilis from E. angustifolius , and E. tuberculatus . The morphological differences between the species of the genus and its related species was not adequately recorded and still not completely monographed, despite the taxonomical importance of the genus (Prasannan et al, 2020). So, identifying the species using morphological characters is very difficult and therefore, the anatomical key probably could augment the identification of three Elaeocarpus species.…”

“…Moreover, the phylogenetic relationship between Elaeocarpus species are poorly understood, and only a few molecular studies have been undertaken so far, with the number of loci and taxon sample being limited (Prasannan et al, 2020). In addition, some of the taxonomic studies carried out in the past (Irudhayaraj & Ramasubbu, 2014; Irudhyaraj & Ramasubbu, 2017; Meijer, 1995; Murti, 1993; Ramamoorthy, 1976; Ramasubbu & Irudhyaraj, 2016; Saldanha, 1984; Vijayan, 2017) had also assisted in the identification of the genus in the Indian subcontinent.…”

“…The family Elaeocarpaceae comprises of nearly 615 species belonging to 12 genera (Christenhusz & Byng, 2016). Among them, Elaeocarpus L. is the largest genera comprising of 360 species (Prasannan et al, 2020) and is found from Madagascar in the west through India, Southeast Asia, Southern China, and Japan, Australia to New Zealand, Fiji, and Hawaii (Coode, 2007). Elaeocarpus commonly occurs in humid and subtropical regions and includes both shrubs and tree species.…”

The vegetative anatomy of Elaeocarpus angustifolius Blume, Elaeocarpus tuberculatus Roxb., and Elaeocarpus variabilis Zmarzty were investigated to illustrate anatomical variations. Plant materials were free-hand sectioned using a razor blade and stained with different staining solutions. The maceration technique was used to assess stomatal characteristics. Elaeocarpus leaves have abaxial epidermis with paracytic stomata and curved anticlinal walls in E. angustifolius, straight walls in other two species. Trichomes were absent in E. angustifolius.hav Mesophyll dorsiventral, midvein cortex contains starch grains, and vascular tissues enclosed by thick-walled sclerenchymatous cells. The petioles of all the three species possess unicellular epidermal hairs, collenchymatous hypodermis, and cortex containing druses and crystals, and vascular tissue enclosed by sclerenchymatous fibers. Water-storage cells are absent in petioles of E. angustifolius. Anatomical features of Elaeocarpus stem include epidermal hairs, epidermis covered by thin cuticle, the collenchymatous hypodermis and vascular integrity with entire cylinder enclosed by sclerenchymatous fibers. Pith contains water-storage cells. Starch grains absent in the pith cells of E. tuberculatus. The roots of Elaeocarpus possess unicellular root hairs, cortex 12-14 layered in E. tuberculatus and E. variabilis and 10-12 layerd E. angustifolius, Endodermis O-thickened and pericycle single-layered in all the examined Elaeocarpus species. Vascular bundles are arranged radially. Lignin deposition occurred in stellar region of roots. Water-storage cells present in the stelar regions of E. variabilis.The study revealed significant anatomical differences between the three Elaeocarpus species and most of these anatomical features may be used as markers for the identification of these species. Research Highlights• Comparative anatomy of three south Indian Elaeocarpus was studied.• Leaf mesophyll layers varied in all the Elaeocarpus species.• Crystals was present in petiole of all examined Elaeocarpus species.• Starch grains was absent in stems of E. tubercuatus, but present in E. variabilis.• Water-storage cells observed in stellar region of E. variabilis.

Meanwhile, the treatment with 7.5 mg/L picloram or 2.5 mg/L 2,4-D in E. grandiflorus culture media grows calli optimally and increases the total phenol concentration as a leading bioactive compound group. 13 High bioactive productivity, represented by secondary metabolite profile including content composition and concentration. Optimization of the picloram and 2,4-D concentration in the cell cultures still needs to be conducted. It is necessary to determine the optimal doses of synthetic-auxin to increase secondary metabolite productivity in E. grandiflorus cell suspension cultures. Therefore, this study aimed to analyze the effect of picloram and 2,4-D on the secondary metabolite profile of E. grandiflorus cell suspension cultures. Materials and MethodsThis research was an experimental study using E. grandiflorus cell suspension culture. A 2-year-old E. grandiflorus plant was collected from Bali Botanical Garden,
