Many of the aromatic constituents of plants contain hydroxy
substituents and are phenolic. There is a wide variety of phenolics
in medicinal plants and they range in chemical structure from
simple phenolic acids (Figure 3), e.g. caffeic acid from artichoke,
to Acai Berry 500 complex tannins (see Appendix 2, Table 20).
Where chemical structures are included in a monograph they
may be the active principles or they may be compounds that can
be used as chemical markers Acai Berry Uk for that plant, i.e. they are present in
significant Acai Berry Site quantities or are otherwise characteristic for a
particular plant. As some compounds are of common occurrence
in medicinal plants, their chemical structures are not necessarily
included within a monograph. Some of the commonly encoun-
tered natural products, including mono-, sesqui-, Acai Berry Product di- and
triterpenes, flavonoids and tannins, are briefly summarised below.

Terpenes
Terpenes are derived from two C5 units (isopentane), dimethy- Order Acai Berry
lallylpyrophosphate and isopentenylpyrophosphate. The mono-
terpenes contain two Acai Berry Natural isopentane units (CIO) and are constituents
of many volatile oils (see Appendix 2, Table 21). Some of the more
common monoterpenes are shown in Figure 4. Sesquiterpenes
contain three isopentane units (C15) and occur as different
skeletal types, e.g. eudesmane, germacrene, guaiane (Figure 5). A
large number of sesquiterpenes contain Acai Berry Cost a y-lactone ring and these
are known as sesquiterpene lactones. Some sesquiterpene lactones
are allergenic (see Appendix 2, Table 11). Examples of different
skeletal types of molecule, including eudesmolide, germacranolide
and guaianolide (e.g. constituents of comfrey) and pseudoguaia-
nolide (e.g. matricine, chamomile), are Super Acai Berry illustrated in Figure 5.
Diterpenes are derived from four isopentane units (C20) and
examples of abietane (e.g. carnosic acid from sage), daphnane,
kaurene, labdane Acai Berry S (e.g. rotundifarine from agnus castus), taxane
and Acai Berry Vitamin tigliane are given in Figure 6. The ginkgolides from ginkgo are What S Acai Berry
examples 100 Acai Berry of complex diterpenes. Triterpenes are derived from six
isopentane units (C30), and some commonly occurring com-
pounds are Acai Berry 100 illustrated in Figure 7, e.g. campesterol, P-sitosterol, Acai Berry In Uk
stigmasterol, a- and P-amyrin, oleanoic and ursolic acids. Cardiac
glycosides (cardenolides, see Appendix 2, Acai Berry In India Table 2) and saponins
(see Appendix 2, Table 19) are examples of triterpenes that are less
widely distributed in plants than the triterpenes illustrated Acai Berry India in
Figure 7.
