“…Although macroscopic and microscopic observations of flowers [45][46][47][48][49][50][51][52][53][54] and leaves [55] of several Asphodelus species have been documented, data regarding the anatomy of root tubers are scarce.…”

Root tubers of Asphodelus bento-rainhae subsp. bento-rainhae (AbR), an endemic species with relevant interest due to conservation concerns, and Asphodelus macrocarpus subsp. macrocarpus (AmR) have been traditionally used for culinary and medicinal purposes, mainly associated with skin infection and inflammation. The present study aims to establish the quality control criteria for the proper characterization of dried root tubers of both species as herbal substances, together with their preclinical safety assessments. Botanical identification using macroscopic and microscopic techniques and phytochemical evaluation/quantification of the main classes of marker secondary metabolites, including phenolic compounds (flavonoid, anthraquinone, condensed and hydrolysable tannin) and terpenoids were performed. Additionally, in vitro genotoxicity/mutagenicity was evaluated by Ames test. Evident morphological differences in the development of tubercles (3.5 × 1 cm in AbR and 8.7 × 1.4 cm in AmR) and microscopicly in the arrangements and characteristics of the vascular cylinder (metaxylem and protoxylems) were found. Anatomical similarities such as multiple-layered epidermis (velamen) and the cortex area with thin-walled idioblasts (134 ± 2.9 µm and 150 ± 27.6 µm) containing raphide crystals (37.2 ± 14.2 µm and 87.7 ± 15.3 µm) were observed between AbR and AmR, respectively. Terpenoids (173.88 ± 29.82 and 180.55 ± 10.57 mg OAE/g dried weight) and condensed tannins (128.64 ± 14.05 and 108.35 ± 20.37 mg CAE/g dried weight) were found to be the main class of marker secondary metabolites of AbR and AmR extracts, respectively. No genotoxicity (up to 5 mg/plate, without metabolic activation) was detected in these medicinal plants’ tested extracts. The obtained results will contribute to the knowledge of the value of the Portuguese flora and their future commercial cultivation utilization as raw materials for industrial and pharmaceutical use.

“…The successive/simultaneous cytokinesis dichotomy has been useful to distinguish Anthericaceae (now placed within Agavaceae, APG II, 2003), displaying successive cytokinesis, and Asphodelaceae, which have simultaneous cytokinesis (Dahlgren et al, 1985;Stedge and Nordal, 1994;Kativu, 1996). Monosulcate pollen is found as the usual condition in most families in the lower asparagoids, from Hypoxidaceae (Rudall et al, 1997) to the better documented Asphodelaceae (Diaz Lifante, 1996;Xiong et al, 1998;Kosenko and Sventorzhetskaya, 1999), but also in Iridaceae (Goldblatt et al, 1991;Le Thomas, 1992, 1993;Pinar and Do ¨nmez, 2000). The higher Asparagales also mainly have monosulcate pollen (Rudall et al, 1997).…”

“…In a recent palynological study of all species of Aspliodeliis (Diaz Lifante, 1996), important taxonomic and phylogenetical inferences at sectional level have been obtained. Pollen grains of Asphodelirs section Asphodelits were described as heteropolar, isobisymmetrical, with exine surface psilateperforate and markedly undulate in the distal face.…”
