some essential oils such as Levisticum spp. and eryngium spp. are heavy and we gathered them in the bottom of clevenger apparatus. what are other plants
Can you frame your question in quantitative terms to understand what you mean by "heavy essential oils"? Are you referring to their specific gravity, their relative predominance when characterizing the composition, etc., of the plant in question?
There are many research papers on this topic. Please consult. Many plant extracts and essential oils contan heavy metals like arsenic, mercury, lead, cadmimum, etc.
A SciFinder search yielded more than 500 essential oils yielding plants.
A webcrowler search gave this link for essential oils

Vetiver roots yield an essential oil that is heavier than water and settles at the bottom of the collecting vessel.
All the aromatic plants have heavy metal, but different the levels.
As for your question, the essential oil of plants have not heavy metal

example for plant with heavy essential oils are cinnamon leaf, clove they contain more than 75 % of eugenol and therefore heavier than water
Essential oils that content more than 50% of safrol, apiol and related compounds from some species of Lauraceous and Piperaceous plants are heavier oils.
yes other than eugenol content, what is given in Andria answer is correct
The plants Cinnamomum officinale, Salvia officinalis, oriandrum sativum, Eugenia cariophyllus,Eucalyptus globulus and peel of citrus limonis fruit contain heavy essential oil.
Laurelia sempervirens, contains 85% of safrol ( D:1,10 g/cm³) in the EO
which kinds of essential oils can be recognize as pure essence? by having more than 70% of one component?
Talking about essential oil, it should concern to a natural formula. All of chemical constituents in an essential oil has a contribution to produce a specific aroma of the oil, event their appear in a trace amount in the oil. That is the reason why the natural essential oil aroma is almost impossible to produce synthetically. This also applies to their pharmacological effects.
The heavier essential oils that extend the life of the more volatile oils are called fixing oils or fixatives. Some of the best known fixatives are Ylang Ylang, Pachouli, Myrrh and Sandalwood Essential Oils.
