“…Higher concentrations of solutions of the studied agents, as in medicine with pharmaceuticals, had a depressing effect on a living organism-silkworm grena. In cases using higher concentrations of extracts (2,4), a slight increase in revitalization (ATEN 1.0-1.25%) or a serious decrease (AANN 1.0-8.25%) was recorded. In variants (1,3,5), where grena was treated in solutions of agents with a lower concentration, an increase in the yield of caterpillars (revitalization) by 4.50-8.75 absolute percent was observed.…”

“…To date, as a result of the studies, one of the effective biostimulants for increasing the yield of rice are natural sesquiterpenoids α-santonin, zerumbon and C 16 -guayanolide, isolated from various plants, increase the yield of rice after one-day soaking of seeds in their solutions at a dilution of 1:10000 compared with control at 14.17% (santonin, zerumbon) and 7.5% (C 16 -guayanolide) [4,5].…”

This chapter is devoted to the phytochemical study of sesquiterpene lactones of some plants of the Asteraceae family and their biological activity. At the same time, the effective growth activity of sesquiterpene lactones isolated by us from plants of the genus Artemisia was established, which improves the quality and increases the yield of rice, cotton and the productivity of mulberry cocoons. Also, a clear mutagenic, anti-nosema, antiviral and insecticidal activity of the amount of lactones isolated from plants of the genus Centaurea, Acroptilon and Handelia was revealed. A technology has been developed for obtaining biologically active compounds from plant materials and methods for the quantitative and qualitative determination of sesquiterpene lactones in plant materials and extracts.

“…The growth-regulating activity of a number of sesquiterpenoids was described in [7,8], and it was found that α -santonin (1), zerumbone (2), and C16-guaianolide (3), (Fig. 1) when rice seeds were soaked for 24 hours in solutions of the above compounds at a dilution of 1:10000 increase the yield of rice compared to the control by 14.17% (α-santonin and zerumbone) and 7.5% (C16-guaianolide).…”

As a result of the conducted phytochemical studies of sesquiterpene lactones of some plants of the genus Artemisia, Centaurea, Jurinea, and Handelia of the Asteraceae family and the study of biostimulating, mutagenic, and insecticidal activity of isolated individual lactones and total preparations in rice farming, cotton growing, as well as against termites, the following biologically active environmentally safe natural remedies have been created: an effective stimulant that, when soaking rice seeds, increases the yield 12-14 quintals per hectare as an average, promising mutant lines and two new cotton varieties have been created on the basis of the polar lactone sum (PLS), and anti-termite sesquiterpene lactones have been isolated, which at low concentrations destroy termites by 90-96%.

“…Since 1, the principal component, shows a variety of physiological effects, e.g., anti-cancer, 28,29) HIV inhibitory, 30) anti-inflammatory, 31) plant growth regulatory, 32,33) and Epstein-Barr virus-inhibitory effects, 28) it was anticipated that the zerumbone derivatives might exhibit useful biological activity. It is notable that 1 has much biological activity, but it is important that the compound, which has a cyclic system, was changed dynamically by the structural transformation and showed biological activity that 1 did not have.…”

Zerumbone is a cyclic seaquiterpene and, a potential resource for natural materials-related diversityoriented synthesis (NMRDOS). Zerumbone, the main component of the essential oil of a wild ginger, Zingiber zerumbet Smith, showed strong reactivity with good chemo-, regio-, and stereoselectivity. To build the foundations for the industrial use of zerumbone, we examined conjugate addition, transannular reactions, ring cleavage, ring expansion, and asymmetric induction. The biological activity of zerumbone derivatives was also studied.
