“…Borkowski and Drost (1965) showed the presence of four compounds in the herb of B. scoparia and B. laniflora (formerly classified as B. arenaria) (Borkowski and Drost 1965). B. indica was also reported to contain three alkaloids, which accumulate in seeds (512 mg/100 g dw), pericarp (387 mg/100 g dw), shoot (up to 294 mg/100 g dw) and roots (85 mg/ 100 g dw) (Zahran et al 1982). The research carried out at that time was mainly based on the reaction of the isolated substances with Dragendorff's reagent and did not lead to the determination of the structure of alkaloids (Zahran and Wahid 1982).…”

Only Drost-Karbowska (1978) on the basis of spectroscopic techniques (UV, MS, NMR) showed that compounds found in aerial parts of B. scoparia are harman and harmine, belonging to the indole alkaloids with βcarboline skeleton (Drost-Karbowska et al 1978).…”

Current knowledge on genus Bassia All.: a comprehensive review on traditional use, phytochemistry, pharmacological activity, and nonmedical applications

Bassia All. is a genus from the Amaranthaceae family, which was created by merging selected species belonging to the former Bassia and Kochia genera with those classified to Chenolea, Londesia, Kirilowia and Panderia. The reorganised Bassia genus currently comprises around 20 species, which are annual herbs or perennial subshrubs native to Eurasia and Africa. Bassia plants are well known for their therapeutic applications in folk medicine and traditional medical systems, and they are also used for nonmedical purposes. Some members of this genus, such as Bassia scoparia (syn. Kochia scoparia) is of great medical importance and economic value. The plant is cultivated in some regions of Asia as a crop to collect Kochiae fructus, which is used for both curative and food purposes. Phytochemical studies carried out on Bassia species indicate that these plants synthesize metabolites belonging to different groups of compounds (e.g., triterpene saponins, sterols, flavonoids, fatty acids, lignanamides, alkaloids, organic acids). Some of the structures are rarely found in the plant kingdom. Biological activity studies carried out on Bassia plants revealed various effects exerted by extracts and isolated compounds, including anti-inflammatory, cytotoxic, antioxidant, antimicrobial, hypoglycemic, anti-obesity, etc. Modern research explained some of the mechanisms of action. This review covers literature from 1935 to 2022, and assembles and discusses data on phytochemistry, biological activity, as well as medical and nonmedical use of the representatives of the genus Bassia. In this review we present the current state of knowledge about the plants of the genus.

“…Consequently, a relatively large part of seed coat is in contact with the soil water. Further, the seeds of K. indica have high (10.86 %) moisture content (Zahran and Wahid 1982) which may also contribute to higher germination of seeds at low soil moisture.…”

Seven plant species including three chenopods: Suaeda fruticosa, Kochia indica, Atriplex crassifolia and four grasses: Sporobolus arabicus, Cynodon dacfylon, Polypogon monspeliensis, Desmostachya bipinnata, varied greatly in their seed germination and growth responses to soil moisture or salinity. The germination percentage of each species was significantly lower at soil moisture level of 25 % of water holding capacity than at the levels ranging from 50 to 125 %. Increase in salinity resulted in gradual decrease in seed germination of each species. Growth responses of species to salinity varied widely from significant decrease with slight salinity to stimulation up to salinity levels of 20 dS m -1. Higher K+/Na + ratios in plant shoots of all species compared to that in the root medium indicated selective K + uptake. Higher tolerance in chenopod species seems to be attendant on their ability for internal ion regulation.

“…Such high reserve accumulation is noteworthy when compared to some other halophyte seeds. For instance, sugar accumulation in the propagules of A. marina was about 3-fold higher than in the seeds of Halophyrum mucronatum (L.) Stapf [21] and 75-fold higher than in the seeds of Kochia indica Wight [22]. The high sugar content in the A. marina propagules is considered as an avoidance mechanism that reduces water loss from the propagules by the high ambient osmotic pressure [5].…”

Avicenna marina (Forssk.) Vierh is a halophytic mangrove. The reproductive unit is green and has photosynthetic propagules. Mangroves are naturally exposed to fluctuations in some abiotic factors at the soil surface, including salinity and alkalinity. The objective of this study was to determine the effects of two salts including NaCl and NaHCO 3 on germination processes and discuss the relationships between cotyledon photosynthesis and embryo axis growth in A. marina propagules. These propagules came from Al Birk, located on the shoreline of the Saudi Red Sea. The results showed that the studied salts did not affect neither the final germination percentage nor the embryo axis growth. However, rooting and root growth were delayed by both salts at 300 mM and were strongly inhibited by 600 mM NaHCO 3 . Both NaCl and NaHCO 3 reduced the photosynthetic activity. These two salts did not affect the other photosynthetic parameters, including stomatal conductance, net transpiration, and intercellular CO 2 . Thereafter, the reduction in net photosynthesis was not related to any limitation of stomatal conductance. The early germination phase was independent of cotyledon photosynthesis, whereas rooting and root growth may be limited by reduced photosynthesis under NaCl and NaHCO 3 .
