Syzygium Aromaticum, Curcuma Longa, and Lavandula: Volatile Components and Antioxidant Activities
Published in Amit Baran Sharangi, K. V. Peter, Medicinal Plants, 2023
Characteristic volatile components were obtained not only from flowers but also from herbs, and they were affected by cultivar type, plant part, and growth season. Camphor, which activates sympathetic nerves, was identified from LX flowers in the plant garden. In both species, the number of volatile components from flowers in summer was greater than that in autumn. In summer, plants produce more volatile components to attract the insects essential for pollination. The number of volatile compounds originating from herbs varies with the growth season, with the fewest produced in winter.

All the plants of the area are identified. A list of the local plants classified into anemophilous, entomophilous and amphiphilous on the basis of their mode of pollination is made. Pollination is the transfer of the male reproductive structures (pollen) to the female structures of the same species. Pollination is accomplished by several methods. Most flowering plants are pollinated by insects (entomophilous). In such plants, the flowers may be colorful, fragrant and attractive to the pollinating agents. The pollen wall is covered by sculptures and often has a sticky coating. The pollen of importance in aerobiology are from plants in which the wind is the pollinating agent (anemophilous). In these plants, the flowers are usually small, inconspicuous, numerous and odorless. Pollen in these flowers are mostly small, smooth and non-sticky and so get airborne easily. In some plants the pollination may be by wind as well as by insects (amphiphilous).

The Sapindus emarginatus tree is 10 m high with a dim, dark-colored bark. Leaves are paripinnate, alternate, forceful, tomentose, and swollen at the base (Arora et al. 2012). Its seeds are yellow and brown in color. Pollination of the flowers is done by insects. Blooms are polygamous, greenish-white.

Greater plantain (Plantago major L.) is a perennial herbaceous polycarpic plant of the family Plantaginaceae Juss. The generation time for this plant species is July–August. The species is diploid (2n = 12), wind pollinated, and characterized by a high level of self-pollination and high seed productivity (van Dijk and van Delden 1981). These features make P. major a convenient species for transgenerational research. It reproduces mainly by seeds, the spread of which is involuntarily promoted by humans (anthropochoria) (Zhukova 1997). The seeds can be transported over considerable distances on shoes, clothes, and on the wheels of cars. P. major is well studied for its genetic and biochemical characteristics since it is used as a medicinal plant (van Dijk and van Delden 1981; Samuelsen 2000; Squirrell and Wolff 2001).

Pollination is a key ecological service, crucial for preserving a healthy ecosystem (Potts et al.2006, Klein et al.2007). Among various pollinating agencies, animal-mediated pollination (through bees and other pollinators) contributes to pollinating one-third of crops utilized by humans (IPBES 2016). This means that globally 87 out of 115 major crops (Klein et al.2007, Hu et al.2008) and around 90% of wild flowering plants (Ollerton et al.2011) get benefited from pollinators’ visits. The estimated value of this service, adjusted for inflation in March 2020, ranged from 195 (Bauer and Wing 2016) to 387 (Lautenbach et al.2012) billion US$ annually. The importance of pollinators gained significant importance because the area under pollinators’ dependent crops has increased by 4-folds (Aizen and Harder 2009). Reduction in pollinators’ population will surely affect the economy of an area like California where almonds, a highly pollinator-dependent cash crop, is grown. Worldwide, there are 20507 bees' species (Ascher and Pickering 2021) that contribute a significant role in this essential service. Among these, Apis mellifera Linnaeus is a very important bee species. It is due to the standard practices developed for hiving of this species that facilitated successful migration of the colonies to the desired area for accomplishing the pollination.

The importance of beekeeping to society is enormous. According to 24, the primary insect species responsible for crop plant pollination around the world is Apis mellifera, which is also domesticated for the production of wax, honey, and royal jelly. Beekeeping has been practiced in different parts of Nigeria. However, there have been speculations that the continued existence of Nigerian honeybee colonies is related to the environment they live in. Similarly, bacterial and fungal associations with honeybees have been used as an indication of how healthy the honeybee colony is [13]. The report of 25, also affirmed that gut microbial load count and digestive enzymes are useful tool of evaluating the health status of invertebrate organisms. Therefore, in an attempt to monitor the health of the Nigerian honeybee, Apis mellifera adansonii, gut digestive enzymes and gut and body surface microbial (fungal and bacterial) association of honeybee workers from the rainforest, guinea savannah, and derived savannah zones of Nigeria were evaluated in this study.
