Encompassing approx 6000 medicinal plant species, the medicinal flora of Asia and the Pacific comprise a fantastic source of pharmacologically active products, and the number of plant species principally used for the treatment of inflammation can be estimated to be more that 380. This chapter will focus on the potentials of medicinal plants of Asia as a source of original anti-inflammatory drugs, with particular interest payed to inhibitors of phospholipase A2, COX, lipoxygenases, elastase, and NOS. [Pg.17]

In this example different methods of cluster analysis are applied to terpene data from wild growing, flowering Hyptis suaveolens originating from different locations in El Salvador (Grassi et al. 2005) it is a frequently used aromatic and medicinal plant of Central America. The collected plants were hydrodistilled and the resulting... [Pg.286]

The risks associated with pesticides that are in use in organic farming have hardly been investigated. Most pesticides allowed in organic farming are of natural origin such as silicates or extracts of medicinal plants. As far as active ingredients are concerned, only three are permitted Rotenone, pyrethroids and copper. [Pg.51]

The ancient Chinese wrote extensively on medical subjects. The Pen Tsao, for instance, was written about 2700 B.c. and contained classifications of individual medicinal plants as well as compilations of plant mixtures to be used for medical purposes. The Chinese doctrine of signatures (like used to treat like) enables us to understand why medicines of animal origin were of such great importance in the Chinese pharmacopoeia. [Pg.3]

Garlic (.Allium sativum) and onion (Allium cepa) are among the oldest of all cultivated plants and originated in central Asia. Garlic has been used as a spice, food, and folklore medicine for over 4000 years and is the most widely researched medicinal plant (see Ali et al., 2000). [Pg.477]

Aloe (Aloe arborescens) is a medicinal plant rich in aromatic polyketides such as pharmaceutically important aloenin (a hexaketide pyrone), aloesin (a heptaketide chromone), and barbaloin (an octaketide anthrone) (Fig. 4a). Pentaketide chromone synthase (PCS) and octaketide synthase (OKS) are novel plant-specific type III PKSs, which were obtained from the aloe plant by RT-PCR cloning using degenerate oligonucleotide primers based on the conserved sequences of known CHS enzymes [30-33]. The deduced amino acid sequences of PCS and OKS are 91% identical (368/403), and show 50-60% identity to those of other CHS superfamily type III PKSs of plant origin OKS shares 60% identity (240/403) with CHS from... [Pg.47]

A series of new examples has recently emerged in the literature. Aquaticol (10), an unusual cuparane-type bis-sesquiterpene isolated from the medicinal plant Veronica anagailis-aquatica, can be derived from a Diels-Alder cyclodimerization of the ortfco-quinol 11, itself derived from an enantiospecific oxidative hydroxylation of (—)-d-cuparenol (12) (Figure 5) [37, 38]. Sorbicillinoid members of the vertinoid polyketide class of natural products also present the same chemical filiation inasmuch as they appear to originate biosynthetically from the sorbicillinol (13)-derived ortho-quinol 14 (Figure 6) (Section 15.3.3) [39, 40]. [Pg.544]

In this chapter, we summarize the current knowledge of interesting terpenes found in Mexican medicinal plants, with special emphasis on the zoapatle (Montanoa tomentosa), a plant originally called "cihuapahtli." This means woman s medicine, and it was used to assist women during difficult labor because of its specific uterus contraction effect caused by the diterpene active substances. Finally, some aspects of the current use of medicinal plants in different cultural environments will be discussed. [Pg.286]

This chapter summarizes the current knowledge of a small part of the Aztec knowledge concerning some sesqui- and diterpenes from Mexican medicinal plants. New anti-inflammatory drugs are being designed based on the mechanism of action of some of these, and other medicines are still to be developed once are able to elucidate their mechanisms. Finally, the current cultural differences produced by the use and abuse of these plants outside of their original cultural context is discussed. [Pg.305]
